The idea that the way to protect insects, fish and animals is by preventing human beings from having children is part of an approach known as Population, Health and Environment (PHE) which integrates population control into environmentalist initiatives. PHE dates back to the 1980s and is practiced by mainstream organizations such as the World Wildlife Fund. The Smithsonian’s Woodrow Wilson Center, which is funded partly by the US government, aggressively champions PHE eugenics and USAID funds PHE programs and distributes PHE training manuals derived in part from Wilson Center materials.
