Habitat loss is when loggers and fishermen hurts the environment. When loggers cut down trees they are killing the trees that animals live in. Fishermen are catching to much fish and the rivers get decreased in population. today there's laws on how many fish you can take out of a river. The earth has warmed slightly over the past years.
