OVER POPULATION “Whether we accept it or not‚ this will likely be the century that determines what the optimal human population is for our planet. It will come about in one of two ways: Either we decide to manage our own numbers‚ to avoid a collision of every line on civilization’s graph – or nature will do it for us‚ in the form of famines‚ thirst‚ climate chaos‚ crashing ecosystems‚ opportunistic disease and wars over dwindling resources that finally cut us down to size” – Alan Weisman

The Population Problem Two hundred years ago‚ Thomas Malthus‚ in An Essay on the Principle of Population‚ reached the conclusion that the number of people in the world will increase exponentially‚ while the ability to feed these people will only increase arithmetically (21). Current evidence shows that this theory may not be far from the truth. For example‚ between 1950 and 1984‚ the total amount of grain produced more than doubled‚ much more than the increase in population in those 34 years.

We have taken over a vast majority of the land‚ thus decreasing the habitats and removing parts of the food chain that are required to keep an ecosystem stable. Hunting is not only to lower the population of a
