In making the recommendation EPA Chair Dr Tom Hatton said changing the technology from a gasification process to a combustion process, which is widely used around the world, did not bring any further risks to the surrounding environment or communities. Overall, the review found stakeholders were supportive of the new framework.
With all the talk of desalinization of ocean water for drinking, what do we know about the impacts this might have on climate, ocean salinity and other natural processes? Sourcing fresh water from streams, rivers, lakes and underground aquifers and adhering to strict water conservation measures are much more viable for both economic and environmental reasons in most situations, although some desert regions with thirsty and growing populations may not have many such options.
The relationship between desalinization and climate change is complex. Global warming has increased droughts around the world and turned formerly verdant landscapes into near deserts. Some long held fresh water sources are simply no longer reliably available to hundreds of millions of people around the world.
Meanwhile, expanding populations in desert areas are putting intense pressure on existing fresh water supplies, forcing communities to turn to desalinization as the most expedient way to satisfy their collective thirst.
But the process of desalinization burns up many more fossil fuels than sourcing the equivalent amount of fresh water from fresh water bodies.
Beyond the links to climate problems, marine biologists warn that widespread desalinization could take a heavy toll on ocean biodiversity; as such facilities' intake pipes essentially vacuum up and inadvertently kill millions of plankton, fish eggs, fish larvae and other microbial organisms that constitute the base layer of the marine food chain.
And, according to Jeffrey Graham of the Scripps Institute of Oceanography's Center for Marine Biotechnology and Biomedicine, the salty sludge leftover after desalinization for every gallon of freshwater produced, another gallon of doubly concentrated salt water must be disposed of can wreak havoc on marine ecosystems if dumped willy-nilly offshore.
For some desalinization operations, says Graham, it is thought that the disappearance of some organisms from discharge areas may be related to the salty outflow.
To date there are about desalinization plants in the United States, with in Florida and less than 40 each in Texas and California. Some 20 additional plants are planned for the coast of California in the coming years, unless environmentalists extolling the virtues of conservation and wielding low-flow shower heads and toilets prevail.

Effect of the Environment on Western Settlers As the country grew and expanded, the American people where always one to push their bounds.
In , we proudly, defied England's proclamation of the year, and settled west of the Appalachian mountains. The globalization of Western eating habits is bad for human health and for the environment, according to a new study in the journal Nature.
In the study, David Tilman, a University of Minnesota. Landslides impact the following aspects of the natural environment of the Western Hemisphere: (1) topography/morphology of both the subaerial and submarine surfaces of the earth, (2) rivers, streams, forests and grasslands, and (3) the habitats of native fauna, both on the Earth’s surface and in its streams and oceans (Schuster, in press).
