A geographic area where all the biotic and abiotic components interact forms an ecosystem.
Overpopulation leads to scarcity of various resources, like food and habitat.
Human activities also lead to the destruction of the environment.
Urbanization, deforestation, pollution, and the burning of fossil fuels affect other living organisms and also the abiotic components of the ecosystem.
Global warming, soil erosion, scarcity of drinking water, and pollution of air and water are the few effects of human activities on the ecosystem.
