This happens when we use a natural resource faster that it can regenerate. Overexploitation applies to hunting, fishing and cutting down trees for wood.
Human domestic, agricultural and industrial activities generate large quantities of waste which contaminate the biosphere. Water is indispensable for life, but it’s also extensively contaminated by waste.
The introduction of new species can unbalance a habitat. These new animals or plants can act as predators, transmit diseases or compete for food with local species.
Human needs have an impact on the natural environment. For example, when we build a new road through a natural area many animals are killed by cars when they are crossing the road.
Climate change is making temperatures rise on the planet. It affects different species of plants and animals because it endangers their natural environment.
