How do habitat and wildlife affect me? The loss of or change in species and habitat can threaten ecosystem health and biodiversity, which affect our economic and socio-cultural sustainability. Biodiversity is crucial because ecosystems perform functions that are essential to human existence, such as oxygen and soil production and water purification. Biodiversity also provides us with food, clothing and medicine.

How do habitat and wildlife affect the environment? When habitat and species are lost, biodiversity decreases, resulting in ecosystems that are less stable, are more vulnerable to extreme events and have weakened natural cycles. The naturally occurring results of a healthy ecosystem– such as clean water and air, maintenance of critical nutrient cycles, flood control, pest control and pollination of crops– could be jeopardized as a result of a decrease in biodiversity.
