- Malnutrition, Starvation and Famine.
- Water Shortage.
What effect would uncontrolled population growth have on land?
The population increases so that the demand for food increases, lack of arable land leads to intensive cultivation, reclamation to expand cultivation land on sloping hills increases soil erosion, causes degradation, infertile soil.
What are some solutions to overpopulation?

What is the optimal, sustainable population size of humans?
From an anthropological point of view, there really is no ideal population size. If we look at the world 20,000 years ago, our best estimates suggest fewer than 10 million people lived in the whole world at that time. For every one of those people 20,000 years ago, there are 1000 people today.
