America’s transportation system has emerged as Climate Enemy #1, with cars, trucks and other vehicles now representing the nation’s largest source of carbon pollution, and America producing more transportation carbon pollution per capita than any other major industrialized nation.
American solar energy is booming. Hundreds of thousands more Americans each year are experiencing the environmental and consumer benefits of clean energy from the sun, often generated right on the rooftops of their homes or places of business.
Pollution from agribusiness is responsible for some of America’s most intractable water quality problems – including the “dead zones” in the Chesapeake Bay, the Gulf of Mexico and Lake Erie, and the pollution of countless streams and lakes with nutrients, bacteria, sediment and pesticides.
Today’s agribusiness practices – from the concentration of thousands of animals and their waste in small feedlots to the massive planting of chemical-intensive crops such as corn – make water pollution from agribusiness both much more likely and much more dangerous.
America has made progress in cutting pollution from cars and trucks over the last decade as a result of improved vehicle fuel economy and slower growth in driving. But eliminating greenhouse gas emissions from our urban transportation systems is going to require more than incremental change – it will require transformation.
