Fewer than 800 million people populated the Earth in the mid-18th Century. Today, barely 250 years later, we are more than 7.7 billion and will continue growing until 2050 by at least another 2 billion.

Taking into account the fact that human beings appeared on Earth more than four million years ago, what happened in our recent history for the number of inhabitants on the planet to start multiplying exponentially?

The tipping point was generally accepted to be the Industrial Revolution, but there are many smaller revolutions that contributed to population take-off which have brought the planet to its current dangerous overpopulation: revolutions that are medical, technological, agricultural, financial, transport and demographical in nature, among others.

Following are the main causes of overpopulation:

  • Falling mortality rate

Falling mortality rate, mainly due to medicine: the Industrial Revolution brought with it a revolution in the world of medicine. Scientific progress allowed us, from then onward, to overcome diseases that previously could only end in death. The invention of vaccines and the discovery of antibiotics such as penicillin saved thousands of lives and were a key factor in unfettered population growth. As the number of annual deaths fell, while births remained constant, so the population increased.

  • Progress in food production

For its part, scientific research and technological improvements saw more efficient agricultural production, resulting in year-round crops, more resistant seeds, pesticides, and so on…. these are the aspects that Malthus had not taken into account when putting forth his catastrophic theory condemning the human race to disappear. Improvements In fishing and livestock methods also contributed to the provision of more food with which to nourish the population.

  • Migration and urban concentration:

in certain countries, the impact of migration and accumulation of the population in cities was very important, but not only with respect to demographic growth, but also in relation to wealth generation. n certain countries, the impact of migration and accumulation of the population in cities was very important, but not only with respect to demographic growth, but also in relation to wealth generation.

These are some of the main causes of overpopulation. As you can see, the impact of overpopulation is tremendous. Overpopulation is one of the biggest challenges humanity is facing and threatens the near future of the planet in economic, environmental and social terms.
