“ Climate change presents a serious test for humankind, but it also provides an opportunity for great innovation and adaptation. The United States has risen to such challenges before, and Earth Day inspires us to transcend differences among nations so we may lead the world in protecting our planet from this global threat. Americans across the country are working hard to help limit the pollutants that cause climate change and reduce their impact on the environment, but we must do more. ”

“ My Administration is committed to increasing fuel economy standards and putting more Plug-In Hybrid cars on the road, weatherizing millions of homes, and catalyzing private efforts to build a clean energy future. My Administration is also working to achieve a comprehensive energy and climate policy, one that will lessen our dependence on foreign oil, make the U.S. the global leader in clean energy technology, and prevent the worst impacts of climate change. ”

“ President Theodore Roosevelt emphasized our obligation to future Americans, saying, "of all the questions which can come before this nation, short of the actual preservation of its existence in a great war, there is none which compares in importance with the great central task of leaving this land even a better land for our descendants than it is for us." ”

“ Through investments in scientific research and development, and the vigorous pursuit of alternative and renewable energy, we can create millions of green jobs that allow us to reduce greenhouse gases and excel in a competitive global economy. ”

“ Individuals and organizations can plant trees, use energy efficient lightbulbs, drive fuel efficient cars, hold clean-up drives, and teach young people about environmental preservation. Small changes in our daily lives can have a big impact on our environment. ”

“ American families can also save money by choosing energy efficient products, turning lights off, unplugging appliances, and cutting back on heating and air conditioning. Government and business alike must also take serious and sustained action to protect our valuable natural inheritance. ”

“ To achieve these ends, no issue deserves more immediate attention than global warming. Scientists have already observed alarming shifts in the natural world, including thawing permafrost, melting glaciers, and rising sea levels. ”
