   ❖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.

   ❖One of the major consequences of population growth is the potential for widespread food shortages.

  ❖ Most scientists agree that humans and human population growth are causing climate change by emission of the greenhouse gas carbon dioxide (CO2).

 ❖  International treaties to limit greenhouse gas emissions have not been ratified by every country due to economic and political concerns.
