Even though a higher population can provide more workers, families must be aware of the amount of children they can can support and the amount of resources available. While many large wealthy families can sustain a happy lifestyle, poorer families mustn't surpass the amount of children that they can afford to have. The main reason a population remains happy is because of the amount of food available, and when there are more people, there is a greater demand for food. This correlation between the rise of food prices and the amount of people is the reason that poorer families with more children become less happy. Malthus argues that the human race is becoming endangered because we are getting to big and outgrowing our resources. The earth only has a certain amount of natural resources and our exponentially increasing population will soon be too much for the earth to withstand.
