With the abundant growth of world population at some point there will no longer be enough resources to go around. At the present rate of consumption, oil and gas supplies will last about forty years. Although there is enough coal to last for four hundred years it is damaging to the environment. With this we will see significant scarcity and poverty. Underlying these is a number of problems. One is discrimination. When resources are scarce, those in power often decide who won't get a fair share, and may discriminate against gender, other races, religions, or economic classes. Limited resources due to overpopulation will cause people to move in search of more resources. There are hundreds of millions of migrant people in the world today, seeking food, water, land and work. Scarcity drives legal and illegal immigration into Canada and other industrialized nations as people struggle to survive and support their families. And when insufficiency is acute, people may fight over resources. As world population and consumption grow, environmental impacts multiply, and the limitations of resources worsen. As more people compete for the same resources, social, ethnic, and political tensions increase. This combination drives political instability, declining social health, and greater migration. The succession of overpopulation, consumption, and scarcity has fuelled more than 150 wars since the end of World War II, and driven tens of millions of people from their homes as economic migrants or refugees.
