Explanation:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.
In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.
