For now, the world’s population is still increasing in huge annual increments (about 80 million per year), and our supply of vital non-renewable resources are being exhausted. There are many novels such as The Message: A Novel About Overpopulation that provide an absorbing, entertaining and highly original read to take you on a surprising journey, one that will leave you questioning much of what you thought you knew.

what is overpopulation

Many factors contribute to these unsustainable world human being population trends, including falling mortality rates, underutilized contraception, and a lack of education for girls.

Following are the main causes of human overpopulation:

  • Falling Mortality Rate

The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. Global average life expectancy has more than doubled since 1900, thanks to advancements in medicine, technology, and general hygiene. Falling mortality rates are certainly nothing to complain about either, but widespread longevity does contribute to the mathematics of increasing population numbers.

  • Underutilized Contraception 

The global fertility rate has fallen steadily over the years, down from an average of 5 children per woman in 1950 to 2.4 children per woman today, according to the UN Population Division.

These women aren’t using contraceptives for a variety of reasons, including social norms or religious beliefs that discourage birth control, misconceptions about adverse side effects, and a lack of agency for women to make decisions around family planning. 

When addressing overpopulation, it’s crucial to take an approach of providing empowerment while mobilizing against anybody advocating for the use of coercion or violence to solve our problems. The combined efforts of spreading knowledge about family planning, increasing agency among women, and debunking widely held myths about contraception will measurably change the trajectory of the world’s population.
