To Reveal a Product’s True Cost An Environmental Tax?
Posted on September 29th, 2009 No comments
To Reveal a Product’s True Cost An Environmental Tax?
Sometimes, simple acts such as going to the grocery store can turn into a moral dilemma. Is it better to choose the piece of organic fruit produced on the other side of the country or the non-organic version grown locally, 50 miles away? Are the benefits of chemical-free shampoo worth an extra 5 bucks a bottle? Will I really be able to enjoy a cheap chocolate bar knowing that the growers of the cocoa beans were likely not fairly compensated?
As much as I’d like to say that I always buy the product that is environmentally safe and sustainably produced, in reality, that’s not always the case. First, the sheer amount of information required to be able to distinguish between products is staggering. You need facts regarding environmental impact, transportation costs, and fair trade practices, to name just a few. And there are plenty of misinformation and greenwashing campaigns out there to steer you in the wrong direction.
Second, of course, there are times when the high cost of an ethically made product turns me off from buying it. Even consumers with the best of intentions have their breaking points.
The thing is, companies who go out of their way to implement sustainable practices endure a greater cost of production. Sure, they can sometimes capitalize on this by marketing to conscientious consumers who are willing to pay a bit more, but the fact remains that in today’s system, environmentally minded production is punished.
On the other hand, companies who move their factories (and jobs) to developing countries with lax environmental standards and cheap labor are able to make products at a fraction of the cost and undercut their competitors (while shipping materials and finished goods all around the world and adding to our greenhouse gas problems).
The way it’s set up, high environmental standards in one country drive companies to relocate in places where it’s permissible to pollute in order to compete in the marketplace. Chaco, the Colorado-based athletic sandal company, is a prime example of even a well-intentioned company being forced to follow suit to maintain competitive pricing on their products. In fact, 95% of all footwear in the world is produced in China, whose poor environmental regulation and sometimes dangerous environmental problems are well known.
With current talk about cap and trade emissions programs, this phenomenon may only get worse.
So how do we even the playing field and reward companies for good business practices?
When I think about this problem, I keep coming back to an idea I encountered in a casual conversation with a stranger while traveling. I can’t remember his face or his name, but his idea has stuck with me and festered in my mind for the better part of a year. His take was that putting the financial burden of environmental responsibility on the companies just doesn’t make sense for the reasons I’ve given above. In a global marketplace, it renders companies less competitive than those that operate free of environmental and labor regulations.
Wouldn’t it make more sense to put an “environmental impact” or “ecological footprint” tax on the product itself?
Ugh, a tax?
Initially, I didn’t warm to the idea either. But think about it: adding a tax proportionate to a product’s ecological and social footprint eliminates the cost advantage of irresponsible production. All those environmental costs that are currently not included in our economic system would be factored in and would increase the price of unsustainably made products.
This, in turn, would make moral dilemmas at the grocery store much easier. Is it more sustainable to buy distant, organic produce or local, non-organic produce? The tax-adjusted pricing should inform my decision. Can I afford the chemical-free shampoo? Yes, because the price of its chemical-laden competitors would be raised through the environmental impact tax and eliminate the cost advantage of choosing that product.
The money raised from the tax could fund its implementation and other sustainable programs such as public transportation (high speed rail, anyone?) and alternative energy. Perhaps it could even make a dent in our gaping budget deficit.
Won’t this cost me money?
You may be thinking, “Sure, that’s a good idea in concept, but that will raise my bills - grocery, clothes, everything.” Well, yes, that’s true. But maybe if we see the true cost of the products we casually consume, we can make a more informed decision about what is really necessary to our lives.
Additionally, programs such as this often have the greatest impact on the poor. But this could be compensated for by using some of the tax revenue for need-based assistance programs.
Regardless, running an economic system on the assumption of infinite resources is fundamentally flawed. Currently, environmental impacts such as air pollution, water pollution, and deforestation are not factored into the cost of a product: they are considered “externalities.”
These costs need to be included in the system in a way that does not punish those who engage in sustainable business practices. By taxing a product’s environmental impact, it levels the playing field for the consumer.
Disclaimer
Of course, I am not an economist or policy guru. I don’t know how to implement such a tax or if it would even be possible (though compared to creating a carbon trading market, perhaps it’s not that difficult). This is only the musing of a concerned, intelligent citizen trying to brainstorm ways to make our economic system fit within the bounds of our ecological constraints.
What do you think? Would such a tax have a beneficial effect on our production system? Join the conversation over at our website!

The Global Warming Theory
Posted on September 29th, 2009 No comments
The Global Warming Theory
We have all heard about Global Warming, where the planet’s atmosphere is supposedly heating up. Of course, we as common citizens have no real proof, only what our scientists tell us, along with the Think Tanks and mass media. But how can we trust this when Global Warming researchers have been paid 100s of millions of dollars, and they know if they disagree with global warming theory the money stops being funded and they are out of work?
One of the most fascinating debate points for Global Warming goes something like this; “The majority of scientists say global warming is real and we are already seeing its impact (the drought in the Western USA and the long term drought in Australia.”
This is seriously a flawed argument and let me tell you why. You see it is irrelevant and may not even be true. After all, 55% would be most of the scientists and thus the majority, still leaving a huge contingency of doubters, with plenty of data and research to back up the opposite point of view.
Likewise, during Copernicus’ day only one man believed the world was round, everyone else said it was flat; so the “majority of scientists” argument is irrelevant; majorities don’t mean anything. If you were one of a 100 people and they all jumped off a bridge because they agreed to, would you jump too? That is illogical.
Now then, the second part of the argument has to do with droughts in the world. And we all know that droughts come and go. Remember the Dust Bowl “Grapes of Wrath” in the US? And in the 1950s Australia had a drought just as bad during the same period, same as the one they are having now. This one we notice more because there are more people demanding the same amount of water.
In California, the snowpack this year is normal and anymore puts us above normal, thus, the drought theoretically is over? So, does that mean this so-called Global Warming is over? Of course, not the powers that be, behind global warming will continue to pursue this until it’s no longer in their interests. Think on this.

Go Green With Natural Finishes
Posted on September 28th, 2009 No comments
Go Green With Natural Finishes
Finishes are coatings that are applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear. They also improve the appearance of the structure and are used to enhance the design of rooms.
Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource. There are now paints and finishes on the market that are derived from a renewable resource, which in a small way, helps to reduce dependence on oil, and contributes to a more sustainable world.
The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD). This increases the burden on waste treatment facilities, and can also pollute our natural water sources. In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.
When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world. And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.
Low and no VOC paints have less smell and less impact on air quality. EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.
Switching will not cost you more. Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused. The paint is still washable, and is far less harmful to you, your pets, and the environment.

Both Man and Nature Cause Global Warming
Posted on September 27th, 2009 No comments
Both Man and Nature Cause Global Warming
It will take all of us to make a significant impact in the world against global warming. The earth is in trouble because of the pollution that we may have caused. It would seem that we are apathetic to the earth’s plea for help. Every natural disaster that is happening to the world, to us, is caused by us. We may have caused it directly or indirectly.
One of the more significant effects of the damage that we have caused this planet is global warming. We may have been feeling how it is a little warmer, how the seasons are all in disarray. It is cold when it should have been hot and it is hot when it should have been cold. Typhoons are also stronger than ever before, aside from the fact that it is more frequent. And haven’t you noticed how a little rain could cause floods? Don’t you find that weird? Well, these are all the effects of global warming and we should be alarmed by it.
That is why natural and environmental causes such as the earth day should be supported because aside from minimizing the use of electricity which is by the way one of the causes of global warming. It brings about social awareness to inform those who are oblivious to what is happening to the world and it re-educates those who are aware. Information is the key and it may be the cure if we do it together. Great things are going to happen. Just the recent earth day brought about great changes that will be felt by the people for generations to come. Can you just imagine the positive effects that this will bring to mankind? Earth will benefit if it continues yearly. Who knows maybe one day global warming will no longer be a problem.

Plasma Gasification Plant Benefits
Posted on September 22nd, 2009 No comments
Plasma Gasification Plant Benefits
Plasma Gasification Plant (PGP) projects are being developed by at least five gas plasma technology companies, and there are real benefits to be obtained from this technology for the destruction of Municipal Solid Waste (MSW).
There is some debate still whether the process has been demonstrated to be a vaible technology which can be reliably operated by our waste management companies at reasonable cost and in compliance with all emissions regulations. However, the consensus seems to be largely in acceptance now that the technology is largely proven and inherently cleaner than incineration.
Although, gasification is used as a power generating technology, and gas plasma plants do provide a power feed-in to the local power grid, it should be realised by all that the purpose of selecting plasma gasification is currently that of achieving maximum waste mass destruction. The intent of the PGP is primarily to provide an efficent and clean method of dispoing of large quantities of residual MSW. Plasma gasification, although it does produce energy from waste is not primarliy an Energy from Waste (EfW) or Waste to Energy technology. There are other better proven, more efficient, and potentially always also cheaper ways to produce Energy from Waste, such as incineration.
PGPs suffer a high sacrificial load from the use of power at the electrodes to generate the plasma, and energy is also expended before the MSW reaches the plasma zone in the gasifier in chopping up and ensuring that the particle size of the waste is quite small. For this reason they do expend a large proportion of the power generated just in maintaining their own internal power demand.
However, as a waste destruction method producing an inert residue without creating at the same time high levels of toxic gaseous emissions the gas plasma process excels according to reports made to date. It has every reason to be cleaner as well because the reactions which take place in the plasma state take place so quickly and completely that the toxic organic chemicals produced in other combustion processes simply don’t get a change to be produced.
For a waste management process PGP therefore holds a very good prospect of adoption, as it is a process which is very efficient at diverting waste away from landfill, and thus scores highly among local authority waste disposal engineers who are constantly seeking to comply with regulations to reduce the amount of organic waste sent to landfill.
The PGP process however, also holds another merit and that is that it is being viewed more favourably by the public than incineration, and one main reason for that would be its clean emissions record when compared with incinerators historically.
Throughout Europe the requirement for BMW to be reduced by ever larger percentages necessitates the use of new technology to achieve this high rate of waste diversion, even after high recycling has also been achieved.
Look out for a plasma gasification plant appearing in a district near you soon, and look favourably upon it!
Steve has built a great web site where there are a lot more facts about gasification. This is a hot subject indeed for this technology which has become an essential read for all those who appreciate renewable energy issues and are interested in taking action to reduce the impact of climate change.Article Source: http://EzineArticles.com/?expert=Steve_D_Evans

A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions
The United States and a host of other foreign countries are focusing on fugitive emission tracking for certain industries. The goal is to identify the amount of substances that are emitted into the atmosphere when a refrigerant gas leak occurs. This will give government officials at the EPA a better understanding of the amount of greenhouse gases harming the environment each year and contributing to global warming due to the ineffective management of refrigerant gases.
Fugitive emission takes place when an unexpected leak of a hazardous substance occurs in a system and the discharge is not contained in a vent, stack, or duct. This may be caused by a component failure, poor servicing, or a breakdown in some industrial process. When a system containing refrigerant leaks, these high global warming potential substances cause damage to the atmosphere. Certain refrigerant gases are not broken down in the atmosphere and end up entering the stratosphere and destroying the protective ozone layer over time.
Across the U.S. economy, refrigerant gases or fugitive emissions equal over 300K tons of carbon dioxide each year. Other countries have similar or worse outputs. Many environmental regulations, such as The Montreal and Kyoto Protocols, exist to reduce the escape of harmful substances, like refrigerants, into the atmosphere over time. There are additional goals to reduce the potential for global warming in the near future and to improve air quality in the long term by reducing the emissions refrigerant gases.
A select few refrigerant gases have multiple detrimental effects on the environment. Not only are they ozone depleting substances but they are also chemicals with a high global warming potential (GWP) which places them into the category of greenhouse gases which lead to global climate change. For many reasons, it is important to effectively monitor, track, and report refrigerant gas usage.
The EPA has finalized its rules pertaining to any fugitive emission occurrence, whether through evaporation or a leak. The regulations apply to several industries, including existing and newly constructed facilities with systems using refrigerant gas in their workplace heating and cooling systems. Other industries are industrial chemical manufacturing, electric services, pulp and paper mills, and petroleum refinancing.
Tracking fugitive refrigerant gases is required by facilities owning or operating HVAC-R systems or by manufacturers who produce them. The EPA has identified a number of dangerous compounds, among them chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform, and carbon tetrachloride.
A particular concern for fugitive emission problems is with refrigerant gas, because it contains chloroflurocarbons and hydrofluorocarbons, two primary contributors to the weakening of the ozone layer and the increase in greenhouse gas volumes. Furthermore, refrigerant gas is used across many industries in refrigeration and cooling units, ventilation and air conditioning systems, and fire protection systems.
When a fugitive emission occurs, businesses are required to track the refrigerant leak rates and report annul refrigerant usage it to the EPA. One of the primary emissions scopes, fugitive refrigerant gas emissions are an integral part of an organizations carbon management requirements. Of the utmost importance is the determination of the HVAC-R system that is leaking and the capturing of the service event detail related to fixing the leak. Systems containing refrigerant gases must be inspected by EPA certified technicians and all service events must be logged when refrigerants are handled.
The new fugitive emission regulations provide a more standardized approach to thresholds identified by the U.S. Clean Air Act at the direction of the EPA. These include continuous monitoring, tracking of leaks, and reporting of leak repair, and containment.
Web applications and specialized tools can increase an organization’s efficiencies related to HVAC-R system maintenance, improve accuracy of refrigerant inventories thus saving money, and turn manual processes into a centralized, automated work flow. Development firms who specialize in the area. They ensure compliance and reduce the likelihood of substantial fines.
Daniel Stouffer, Product Manager at Verisae, has more information about fugitive emissions management. Refrigerant Tracker makes it easy to monitor, manage, and report refrigerant gas usage across multiple locations. Learn more at: http://www.Refrigerant-Tracker.com

THE 3 Rs - Reuse and Recycle, Lazy Ways to Reduce
The 3 Rs (Reduce, Reuse, and Recycle) is no longer simply a mantra for environmental activists, it’s a ticket to saving you money while you consider the planet. The 3Rs ask you to buy less, reuse more, and recycle products at the end of their useful life-wonderful guiding principles for reducing our environmental footprint and bringing our lifestyles into balance with nature. But in practice, how many of us are really willing to cut back on the stuff we want to own, to reuse what we’d like to throw out, and to recycle when doing so is often incredibly inconvenient? Fortunately for budget-conscious Lazy Environmentalists, the 3Rs are receiving a twenty-first-century facelift, making them easy to implement and even easier on the wallet.
Reduce, the first of the 3Rs, releases you from the hassle, expense, and waste of unwanted stuff while helping you use less energy and create less trash. And while most of us can’t imagine life without our most prized four-wheeled possession, the first place to embrace Reduce is with our cars. That’s because our automobiles generate about half of our personal greenhouse gas emissions-the other half comes from our homes.
Today, you can enjoy the freedom of being in the driver’s seat while eliminating all of the expense of owning-or leasing-and maintaining a car by joining a car-share service. Zipcar is leading the way. Available in more than 40 U.S. cities, Zipcar lets members locate cars conveniently parked at designated spots around the city and reserve them for an hourly fee (typically between $10.50 and $16.50). Members arrive at the parking spot, swipe their membership card over the windshield sensor to unlock the door, hop in, and go. There’s no need to pay for gasoline or insurance; Zipcar has got you covered. You won’t sacrifice your ride either; Zipcar lets you choose from models like the BMW 325, Mini Cooper, Honda Fit, Volkswagen Jetta, Toyota Prius, Honda Civic Hybrid, Volvo S40, Mazda 3, and Subaru Outback. According to the company’s surveys, over time Zipcar members reduce their car usage by as much as 50 percent. Zipcar estimates that each of its cars removes the equivalent of about 15 privately owned vehicles from the road. Other car-sharing services are popping up across the country and around the world. Visit Carsharing.net for a comprehensive list.
Reuse-the middle child of the 3Rs-has been a part of our lives before we were “eco” anything (eco-conscious, eco-savvy, even a tentative eco-curious). Think about it: Every day, we reuse items like T-shirts, cereal bowls, and underwear without a second thought. We don’t toss them after one use. We reuse. The secret to twenty-first century Reusing is to discover how to reuse other people’s really cool stuff as well as our own.
Reuse logic is in effect at Goozex.com, where gamers gather to swap their video game. Visit the website, create an account and list the games you own that you’d like to trade. Then Goozex quickly locates other gamers who want them and makes instantaneous matches for you. With each game you mail, you earn Goozex points, which you can then use to acquire the games you want from other members. Instead of spending lots of money on new games (and paying for all that packaging waste), you’ll pay Goozex $1 each time you receive a game. Whether you’re partial to Xbox, Wii, Nintendo, or many other gaming platforms, the Goozex trading community has got you covered. Get your reused copy of Call of Duty 2 or NCAA Football 09 today.
Swapping websites are emerging in all kinds of categories. Bookworms can browse more than two million titles available for trade at Paperbackswap.com. Movie collectors can visit Swapadvd.com to trade both new and classic DVD titles. CD fans (you know you’ve still got ‘em) can tap into more than 130,000 titles available at Swapacd.com. And new and expecting parents can trade for baby strollers, bibs, bedding, bumpers, and more at Zwaggle.com.
Recycle, the last of the 3R trio, is the most transformative of the Rs. When we recycle, we’re giving used products the chance to be reborn as something new. That’s especially the case thanks to companies like Preserve that has partnered with Stonyfield Farm to recycle its yogurt cups-from organic yogurt, of course-into ergonomic plastic toothbrushes, razors, and an assortment of colorful kitchenware (and now also does the same with Brita pitcher filters).
TerraCycle, another green innovator, is on pace to redefine much of America’s relationship with trash. The company that began with its signature Plant Food-made from worm poop, packaged in empty Pepsi bottles and sold at the likes of Home Depot and Wal-Mart-has evolved into an innovation powerhouse that continually introduces new products made entirely from waste. Take the E-Water Trash Cans and Recycling Bins available at OfficeMax for $10.99 each and made from crushed computers and fax machines (that would otherwise end up in a landfill). Or the rain barrels and composters made from Kendall-Jackson oak wine barrels that sell for $99 each at Sam’s Club. They’re both prime examples of a company that sees opportunity where others see garbage. In so doing, TerraCycle helps us make attractive choices that are mindful of the planet and our wallets.

VUE Green Line Hybrid Video Review
Posted on September 17th, 2009 No comments
Yahoo Vs Google - Who’s Greener?
Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment. Google and Yahoo, the search engine giants, are both headquartered in the Valley and have been making headlines by greening their offices, reducing energy consumption, and carbon trading. The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo’s headquarter facilities.
We looked at the ecological services provided by green landscape features such as trees and open space (i.e. grass). Grass and trees are pervious surfaces, meaning they allow water to permeate into the ground. Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live.
In terms of ecological services, trees and grass have been proven to:
1. Remove and store carbon from the atmosphere,
2. Remove certain airborne pollutants,
3. Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and
4. Remove certain waterborne pollutants.
Here is a look at how green Google and Yahoo really are and how the measure up against each other.
Google Green Report
Google’s headquarters, the Googleplex, covers 44 acres, nearly 50% of which is grass or tree canopy. This is an impressive paved to open space ratio. The grass and trees on the Googleplex remove roughly 2 tons of carbon from the atmosphere per year, or 0.04 tons per year per acre. In addition, 530 lbs. of air pollution are removed per year (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter), or 12 lbs. per year per acre. It was assumed that the parking lot of the Googleplex is asphalt, and not a type of porous pavement, so the cost of managing rainfall runoff from the Googleplex is $4,474 per year, or $103 per year per acre. The abundance of grass and tree canopy on the Googleplex go a long way to offset the water quality impacts of the paved surfaces (mainly the parking lot). On average, the grass and trees reduce water pollution by 6%, as opposed to the entire property being paved.Yahoo Green Report
The Yahoo headquarters, Yahooplex, covers 28 acres, a third of which is grass or tree canopy. This is a classic ratio of paved to open space for large office complexes in California. So far, par for the course. The Yahooplex removes 0.36 tons of carbon from the atmosphere per year, or 0.01 tons per year per acre. 114 lbs. of air pollutants are removed per year, or 4 lbs. per year per acre. In terms of rainfall, the cost associated with runoff is $9,219 per year, or $331 per year per acre. The grass and tree canopy help offset the paved areas with a 2.3% reduction in water pollution as opposed to the entire property being paved.The final green analysis?
Google kicks Yahoo’s butt, largely due to the forethought, or luxury, of the Googleplex having 50% of its property surface providing green services. The good news for both Google and Yahoo is that over time, as trees grow, so will the tree’s canopy and mass, thus storing more carbon and removing more air pollutants.
Green next steps for both Google and Yahoo is to:
- Install porous parking surfaces, allowing up to 80% of rainwater to seep into the ground,
- Install green roofs, absorbing rainwater while reducing cooling costs and energy consumption, and
- Planting larger trees on the south and west sides of the buildings to reduce cooling costs and energy consumption.
While we crunched the hard numbers to settle the Google vs. Yahoo green debate, this report illuminates the great opportunity that awaits these two Silicon Valley giants to harness the ecological services of green surfaces.

However, the consensus seems to be largely in acceptance now that the technology is largely proven and inherently cleaner than incineration.
Although, gasification is used as a power generating technology, and gas plasma plants do provide a power feed-in to the local power grid, it should be realised by all that the purpose of selecting plasma gasification is currently that of achieving maximum waste mass destruction. The intent of the PGP is primarily to provide an efficent and clean method of dispoing of large quantities of residual MSW. Plasma gasification, although it does produce energy from waste is not primarliy an Energy from Waste (EfW) or Waste to Energy technology. There are other better proven, more efficient, and potentially always also cheaper ways to produce Energy from Waste, such as incineration.
PGPs suffer a high sacrificial load from the use of power at the electrodes to generate the plasma, and energy is also expended before the MSW reaches the plasma zone in the gasifier in chopping up and ensuring that the particle size of the waste is quite small. For this reason they do expend a large proportion of the power generated just in maintaining their own internal power demand.
However, as a waste destruction method producing an inert residue without creating at the same time high levels of toxic gaseous emissions the gas plasma process excels according to reports made to date. It has every reason to be cleaner as well because the reactions which take place in the plasma state take place so quickly and completely that the toxic organic chemicals produced in other combustion processes simply don’t get a change to be produced.
For a waste management process PGP therefore holds a very good prospect of adoption, as it is a process which is very efficient at diverting waste away from landfill, and thus scores highly among local authority waste disposal engineers who are constantly seeking to comply with regulations to reduce the amount of organic waste sent to landfill.
The PGP process however, also holds another merit and that is that it is being viewed more favourably by the public than incineration, and one main reason for that would be its clean emissions record when compared with incinerators historically.
Throughout Europe the requirement for BMW to be reduced by ever larger percentages necessitates the use of new technology to achieve this high rate of waste diversion, even after high recycling has also been achieved.
Look out for a plasma gasification plant appearing in a district near you soon, and look favourably upon it!
Steve has built a great web site where there are a lot more facts about gasification. This is a hot subject indeed for this technology which has become an essential read for all those who appreciate renewable energy issues and are interested in taking action to reduce the impact of climate change.Article Source: http://EzineArticles.com/?expert=Steve_D_Evans

A Modern-Day “Roman” Aqueduct For Florida

A Modern-Day “Roman” Aqueduct For Florida
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success - and on successes over the centuries since that time - by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.Let’s see whether anyone steps up to the plate.
