The global environmental movements have been in existence for over 50 years, a period marked by profound notable wins.

A good example is the regulation of DDT pesticides. Thanks to these movements, the U.S. Environmental Protection Agency in 1970, and in 1972 issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. The Stockholm Convention on POPs, which bans DDT for all uses except for malaria control. However, we're witnessing a sudden decline in the voices for nature. The damming of rivers and encroachment of wetlands is going on unquestioned.
