Environmental degradation

This phrase refers to the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.[1] As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource depleting and polluting technology (T).[2][3] 

Impacts of Environmental Degradation has a good brief summary of what the term means and specific ways we are degrading our environment. Top concerns are water availability and purity, air pollution, and soil desertification and erosion.

Mark Thiessen reported in the Detroit Free Press in 2015 that polar bears were in peril due to global warming.
