Environmental activism, climate-change activism, has become a belief system, a religion. The genesis of the environmental movement was science-based and sought to protect threatened species and the vital qualities of air and water. The religion of environmentalism focuses on the harmful effects of mankind, mankind as the enemy of the earth.
