Change in the local environmental conditions in which a particular organism
lives.
Habitat change can occur naturally through droughts, disease, fire,
hurricanes, mudslides, volcanoes, earthquakes, slight increases or decreases in
seasonal temperature or precipitation, etc.
However, it is generally induced by human activities such as land use change
and physical modification of rivers or water withdrawal from rivers.
