These are photographs that I have taken in the area around me. The prove that there is a concern with human overpopulation, but if you do not understand the connection I will explain it below.
If the planet was not overpopulated the forests would be preserved, thriving, and being the lungs of the planet and the home of wildlife. Instead we rape the forests for wood or chop them up and burn them to make room for agriculture to grow food for people or food for livestock.
The trees in the distance of both of these photos are not forests, rather they are rows of trees about 30 feet wide, not much more; a poor replacement for all the trees that used to cover the land.
Now I know there are some people who do not see this as an indication of human overpopulation but I ask "When does it stop?" At what point do we say "Ya, enough trees have been chopped, it cannot all be farm land, we need forests?" To me the fact that we are not sustainable and are still cutting trees to make more farm land is proof that we are overpopulating the planet.
I only had one child, that was plenty for me. I live rurally and am allowing trees to reclaim part of the area in front of my house which was once known as a "lawn". We need to stop the destruction of our environment and the only way to do that is to slow our population growth.
