Why have many wildlife species become endangered and rare? Give reasons

1) Pollution: Oil spills, acid rain, and water pollution have been devastating for many species of fish and birds.

2) Hunting and fishing: Many animals are over-hunted because their meat, fur and other parts are very valuable.

3) Destruction of habitat: Humans destroy precious habitat, the natural environment of a living thing, when they fill swamps and marshes, dam rivers and cut down trees to build homes, roads, and other developments.
