How big is the problem?
According to the Intergovernmental Panel on Climate Change (IPCC), if current trends of fossil fuel use continue, the world could see more frequent severe weather conditions and damage to many natural ecosystems. It could also alter the atmosphere leading to extreme temperatures, a rise in sea level, loss of habitat and biodiversity and an increase in the spread of health risks and diseases.
The Environmental Protection Agency(EPA) says the pollution of our water resources can have serious and wide-ranging effects on the environment and human health. Pollution poisons and deforms fish and other animals, unbalances ecosystems and causes a reduction in biodiversity. Ultimately, these effects take their toll on human life. Drinking water sources become contaminated, causing sickness and disease. Pollutants accumulate in food, making it dangerous or inedible. The presence of these toxic substances in our food and water can also lead to reproductive problems and neurological disorders. The EPA studies and monitors the effects of water pollution and uses this information to set healthy emissions standards and enforce environmental regulations.
Accidents, spills, leaks, and past improper disposal and handling of hazardous materials and wastes have resulted in tens of thousands of sites across our country that have contaminated our land, water (groundwater and surface water), and air (indoor and outdoor). Some of the more common categories of contaminants include: industrial solvents, petroleum products, metals, pesticides, bacteria, and radiological materials. These contaminated sites can threaten human health as well as the environment, in addition to hampering economic growth and the vitality of local communities.
The federal government has initiated a program called Superfund to clean up the nation's uncontrolled hazardous waste sites - sites containing asbestos, lead, mercury and radiation.
S. David Freeman, former federal energy official and author of "Winning Our Energy Independence" said in a recent interview when asked about nuclear power projects:
"In 50 years, we haven't found a safe place to put the waste, and the risks of an accident are still so great that private insurance companies won't insure them. Big solar and wind backed up by natural gas is a safer, cheaper alternative for society."
Freeman also noted:
"It will take government tax credits and regulations to require mass production of plug-in hybrids, biofuels and renewable hydrogen-fuel-cell cars to achieve energy independence."*
