However, with American economic rapid developing, the problem of agricultural environment went further worsening in the 1950s and 1960s. Especially, chemistry pollutions caused by excessive utilization of pesticide and fertilizer had seriously menaced public health and life safety.In 1962, Rachel Carson published Silent Spring, which initiated grand environmental protection movement in the United States, and made the governing of agricultural environment go forward a new phrase. Henceforce, American adopted some new measures about agriculture environmental protection, such as law and policy, science-technology and engineering project, propaganda and education. At the same time, American government enhanced large-scaled comprehensive governing to other kinds of the pollution. These measures made the governing of agricultural environment problem gain a great improvement.
