Mural reads: Positive Effects of Climate Change: Hey, more fresh water for everyone! Positive Effects of Environmental Destruction: Hey, my allergies are gone! Positive Effects of Overpopulation: At least the economy is on the rise because there are more people to tax!
These small positive effects are nowhere near equal compensation for the environmental losses occurring in these situations. Climate change causes the polar ice caps to melt, which causes the earth to warm faster, sea levels to rise, and ice-dependent animals to go extinct. Clear-cutting forests removes a carbon sink, an air filter, a habitat, a potential source of income, and it removes the tree roots that hold the soil in place to decrease erosion. Overpopulation uses too many of the world's resources to support the human population, causing other species and the planet to suffer.
