Animals are disappearing at rapid rates: Extinction by the numbers

The planet in the middle of a mass extinction — the sixth time in Earth's history that a wide swath of species are experiencing a major collapse in their populations.Human activities are to blame: Pollution, farming, and deforestation are destroying natural habitats.According to a new report from the United Nations, up to 1 million plant and animal species are threatened with extinction, many within decades.
