The world should reduce world population. This would reduce our impact on the environment.  The Negative Population Growth organization lays out their strategy below:

"Negative Population Growth, Inc. (NPG) is a national nonprofit membership organization. It was founded in 1972 to educate the American public and political leaders about the devastating effects of overpopulation on our environment, resources and standard of living. We believe that our nation is already vastly overpopulated in terms of the long-range carrying capacity of its resources and environment.

We urgently need, therefore, a National Population Policy with the goal of eventually stabilizing our population at a sustainable level, far below today's. after an interim period of negative growth."
