Impacts on Birds & Wildlife

Breeding Bird Surveys from 1947 through the 1970s, revealed that the yellow-billed cuckoo and yellow-throated vireo — as well as the northern parula, black-and-white warbler, Kentucky warbler, and hooded warbler — were disappearing. Six other migrant song birds —Eastern wood-pewees, Acadian flycatchers, wood thrushes, red-eyed vireos, ovenbirds, and scarlet tanagers — had declined by more than 50 percent.  What was going on?

The destruction of the natural world we see across the globe today is "fallout" from the human population explosion that has occurred over the course of the last 50 years. In order to satisfy the needs and wants of ever-increasing numbers of people all over the globe, humans chop down forests, bulldoze mountains, divert streams, spray poisons, introduce invasive species, take out wild animal populations, and pave over land upon which wild creatures depend.

"I understand more and more how population is the problem. I was asking almost every peasant I met how many children they have.

Population growth is a core environmental issue.  The world's forests, rivers, oceans, and wild creatures are perishing at the hands of people. Across the globe, wildlife habitat is being destroyed by chainsaws, bulldozers, and chronic pollution. Much of the destruction of the natural world we see across the globe today is "fallout" from the human population explosion that has occurred over the last 50 years.
