Read the passage from a letter that President Jimmy Carter wrote to Congress in 1977.This message brings together a great variety of programs. It deals not only with ways to preserve the wilderness, wildlife, and natural and historical resources which are a beautiful and valued part of America's national heritage: it deals also with the effects of pollution, toxic chemicals, and the damage caused by the demand for energy. Each of these concerns, in its own way, affects the environment; and together they underscore the importance of environmental protection in all our lives.
