It causes more diseases to spread and makes them harder to control. Today, that rate has lowered to 7. Overpopulation can further be viewed, in a long term perspective, as existing when a population cannot be maintained given the rapid depletion of non-renewable resources or given the degradation of the capacity of the environment to give support to the population.

Starvation is a huge issue facing the world and the mortality rate for children is being fuelled by it. The effects listed on this page are just some of the main problems associated with or exacerbated by human overpopulation.

Elevated Crime Rate As human overpopulation drives resources and basic necessities, such as food and water, to become scarcerthere will be increased competitiveness for these resources which leads to elevated crime rates due to drug cartels and theft by people in order to survive.

Some scientists warn that if present trends continue, as many as 50% of the world’s wildlife species will be at risk of extinction. As population densities increase, laws, which serve as a primary social mediator of relations between people, will more frequently regulate interactions between humans and develop a need for more rules and restrictions to regulate these interactions.

Human overpopulation
