Population growth can have negative effects on housing, food and water access, waste control, and natural resources. Poor management of these issues can lead to disease, famine, and environmental damage. Effective strategies are needed to address these problems.
The effects of population growth are varied and vast. While population growth, of any species, can be beneficial to some degree, there may come a time when population numbers exceed the natural resources available to support it. There is talk of overpopulation. The consequences of such an event are serious and serious.
The population growth of any animal, if left unchecked, can become burdensome. Farmers have noticed, for many centuries, what the effects of a population of uncontrolled predators can do to livestock. Once their natural prey runs out, or is harder to find, predators may turn to pets, despite the risks. This can cause severe hardship for any family that depends on those animals for survival.
However, when most think of a growing population, they don’t think of other animals. The main fear in most people’s minds is the population growth of their own species. Because humans leave a much larger footprint in the environment than any other creature, unchecked overgrowth can be particularly devastating.
First, as population increases quality opportunities, housing availability can become an issue. More people crammed into less space is not a good combination in any location. As space is taken up, it becomes more valuable. Eventually, it starts hitting the poorest in the area. The long-term effect of population growth can be poor housing or homelessness.
In other cases, access to food and clean water may be the main problem. This is an even more immediate problem than housing. As more and more people are faced with unsanitary food sources, disease and famine begin to take root. If left unaffected, it will wipe out an entire population. In some cases, entire countries may be affected by the situation. Finding a solution often requires a multinational effort.
Another negative effect of population growth is waste control. When there are relatively few people around, litter control is a much easier task. However, as populations grow, waste increases dramatically. Finding a place for this waste, or treating it in a way that doesn’t poison the environment, is of paramount importance. Regions of the world that don’t have the capacity to do this will find that it leads to a number of other serious problems and becomes a huge public health problem.
In general, the problem is not population growth per se, it is poor management of natural resources and wastes that cause most of the problems. Many places have found effective strategies to deal with such problems. Other localities, usually due to a lack of relative wealth, and possibly engineering knowledge, lagged behind.
