Danger # 4: Overpopulation

Credit: Kevin Briody, source:

This is another serious danger threatening the Earth and humanity as a whole. The human population is constantly rising at an exponential rate. The time when the Earth wouldn't be able to support us anymore is quite near.

Overpopulation is also aggravating an already serious problem threatening our civilisation: ressource depletion. Our civilization relies on fossil fulels for transportation and various minerals for manufacture. These ressources are not infinite. One day there would be no more left. And unfortunately this day seems to be quite near.

Population Growth Rate in the World

Another consequence of overpopulation is the increase of poverty in the world. This is due to the fact that the population growth is much higher in the poor countries than in the rich ones.

An example of overpopulation: Cairo, Egypt

Only the colonization of space on a massive scale would resolve all these problems in the long term. There is more territory and ressources in space than we will ever need.
