What causes animals to become extinct or endangered? Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms.
