Ecological Disturbance

Ecological Disturbance
Animals and plants are living creatures that are difficult to avoid the effects of warming because most of the land has been controlled by humans. In global warming, animals tend to migrate toward the poles or to the mountains. Plants will change the direction of growth, seeking new areas as old habitats grow too warm. However, human development will prevent this movement. The species that migrate to the north or south is blocked by the cities or agricultural lands may be dead. Some types of species that are not capable of quickly moving toward the poles may disappear.
