Extreme Environments: Extinction (2008)

Episode 22
Available worldwide

Our planet’s untouched natural environments are shrinking, due to pressure from human populations. As these areas decline, the creatures adapted to live in them face a decline in numbers, and sometimes even extinction altogether. Many biologists believe that if we don’t act quickly, half the world’s species will be gone in 100 years. A report called the Living Planet Index reveals that from 1970 to 2000 populations of terrestrial and marine species dropped by 30 percent, while freshwater populations went down by a massive 50 percent.
