| Animals are disappearing at hundreds of times the normal rate, primarily because of shrinking habitats.
Habitat loss – driven primarily by human expansion as we develop land for housing, agriculture, and commerce – is the biggest threat facing most animal species, followed by hunting and fishing.
Even when habitat is not lost entirely, it may be changed so much that animals cannot adapt. Fences fragment a grassland or logging cuts through a forest, breaking up migration corridors; pollution renders a river toxic; pesticides kill widely and indiscriminately.
To those local threats one must increasingly add global ones: Trade, which spreads disease and invasive species from place to place, and climate change, which eventually will affect every species on Earth – starting with the animals that live on cool mountaintops or depend on polar ice.
All of these threats lead, directly or indirectly, back to humans and our expanding footprint. Most species face multiple threats. Some can adapt to us; others will vanish.
