  1. Global warming will make this a lot worse, as large areas of the planet become uninhabitable due to climate change or are inundated by rising sea levels. Wars will increase as nations fight over dwindling natural resources. Positive feed back will see these problems increase at an exponential rate. Only a collapse in the size of the human population might halt the process. This may happen as a result of nuclear war, famine or pandemic disease.
