Habitats are where organisms live. Loss of habitat can range
from the removal of whole wetland ecosystems, to the loss of a
small stand of reeds in a swamp or creek.
The effect of habitat loss is invariably a reduction in biological
diversity. This can limit the ability of the environment to
tolerate climatic variation and the effects of human activities.
It can also affect the ability of the environment to recover from
a major event such as a drought, or a significant pollutant discharge.
