The red curve shows the evolution of population in the world.

If we make a comparison , we see that the population increases more rapidly than the resources. Malthus believed that the size of a population was limited by its food supply. For Malthus , the growth of population is dangerous for the subsistence of the world such as the famine. So , he purposes a volunteer restriction of the births . This theory was based on two principles :
