From Kerry's website
"John Kerry will enter into a "Conservation Covenant" with the American people to tread lightly on the public lands and protect and restore our nation's parks and other treasures for the benefit of future generations. As part of the covenant, John Kerry will implement the Endangered Species Act in a cooperative manner that extends the benefits of wildlife and habitat protection to public and private lands. He will put new teeth into requirements that private companies who lease public lands return the land to its original state. The Covenant will reinvest royalties obtained from extracting resources from public lands back into protecting our lands, and require that before remote public lands are opened up to new resource development, the federal government evaluate the long term economic and environmental costs associated with such actions."
Check out more of his environmental policies. He really isn't like Bush at all in this crucial area. For example, his energy plan doesn't involve invading countries with oil, as Bush/Cheney's plan does. Here's his website summary of his energy plan.
"John Kerry has outlined a comprehensive energy plan that will tap America's initiative and ingenuity to strengthen our national security, grow our economy, and protect our environment. Kerry's plan will increase and enhance domestic energy sources and provide incentives to help Americans use energy more cleanly and efficiently. When sixty-five percent of the world's oil reserves lie beneath the Persian Gulf states and only 3 percent lie beneath America, we cannot drill our way to independence. We can, however, develop and deploy clean energy technologies that will make us more efficient and allow us to capitalize on domestic and renewable sources of energy. John Kerry's plan for a renewable energy trust fund to invest in the development of renewable energy will reduce our oil dependence by more than 2 million barrels of oil a day - about the same amount we import from the Persian Gulf. Kerry's plan will also create 500,000 new jobs over the next decade and work toward producing 20 percent of US energy from renewable fuels by 2020."
That is also radically different than Bush's platform.
In terms of the environment, Kerry is nothing like Bush at all.
