Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects [3] [4] including global warming, [1] [5] [6] environmental degradation [1] (such as ocean acidification [1] [7]), mass extinction and biodiversity loss, [8] [9] [10] ecological crisis, and ecological collapse.
Environmental issues are harmful aspects of human activity on the biophysical environment. This alphabetical list is loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
This trade can be devastating to both humans and animals. It has the capacity to spread zoonotic diseases to humans, as well as contribute to local extinction. The pathogens to humans may be spread through small animal vectors like ticks, or through ingestion of food and water.
