It results in human threats including the evolution and spread of antibiotic resistant bacteria diseases, excessive air and water pollution, and new viruses that infect humans.

We grab all the fish from the sea, wreck the coral reefs and put carbon dioxide into the atmosphere. We have triggered a major extinction event A world population of around a billion would have an overall pro-life effect.

This could be supported for many millennia and sustain many more human lives in the long term compared with our current uncontrolled growth and prospect of sudden collapse If everyone consumed resources at the US level — which is what the world aspires to — you will need another four or five Earths.

Williams [] argue that third world poverty and famine are caused in part by bad government and bad economic policies.

It also depends on how resources are managed and distributed throughout the population. The resources to be considered when evaluating whether an ecological niche is overpopulated include clean waterclean air, food, shelter, warmth, and other resources necessary to sustain life.

If the quality of human life is addressed, there may be additional resources considered, such as medical care, education, proper sewage treatmentwaste disposal and energy supplies.

Overpopulation places competitive stress on the basic life sustaining resources, [] leading to a diminished quality of life.

With the global population at about 7. Weather patterns, elevation, and climate all contribute to uneven distribution of fresh drinking water. Without clean water, good health is not a viable option. Besides drinking, water is used to create sanitary living conditions and is the basis of creating a healthy environment fit to hold human life.

In addition to drinking water, water is also used for bathing, washing clothes and dishes, flushing toilets, a variety of cleaning methods, recreation, watering lawns, and farm irrigation.While public concern about rapid population growth has subsided in recent decades, world population is still growing at about 80 million people a year, or about , people per day.

If current trends persist, there will billion more people on the planet by mid-century, bringing the total to about billion. Apr 01,  · Explaining the evolution of human life history traits remains an important challenge for evolutionary anthropologists.

Progress is hindered by a poor appreciation of how demographic factors affect the action of natural selection. Human overpopulation (or population overshoot) remains a very important issue." A more recent UN projection suggests the population could grow to as many as 15 billion by In , The rate of human population growth peaked in , at about % per year.

Although the global rate of human population growth peaked around , the number of people living on Earth — and sharing finite resources like water and food — has grown by more than two-thirds since then, topping out at over seven and a half billion today, and .
