World population

The world’s population now exceeds 7.8 billion people. Our population is still growing by more than 80 million people every year and is likely to keep growing until the end of the century, unless we take action.

It took the human population until 1800 to reach 1 billion people – we now add a billion more every 12 to 15 years. Since 1970, our numbers have more than doubled.
