The story begins in 1798, Thomas Robert Malthus wrote a 58-page essay on overpopulation. In this essay, he predicted that the world's population would continue to grow and would only be reversed by disease or other natural effects. At the time, it was a success but wasn't supported by too much evidence. Two hundred years later, in the mid-to-late 1960s, his ideas experienced a second surge in popularity, but this time the data was on his side. Immediately, scientists around the world sought to verify his theory with his evidence and many agreed with the results he predicted; a demographic boom that would exceed figures never imagined. In the thousands of years that humanity has lived, such a human population has never been reached and never at this rate. What worried Robert Malthus and these scientists was not the number of people per se, but rather the effects and demands of those people. The fact is that people tend to love living. They tend to like having food, water to drink, a place to live, and any other basic needs. According to the diary written by Malthus, there was not enough to go around; rapid population growth would be too fast for the food production industry to keep up and different states would rush to collect enough to survive. This competition would not stop there since food is not the only resource needed. In short, this would mean that every needed resource would be in competition and war would likely ensue (leading to a state of calamity). Due to lack of resources, it is likely that people will die and the number is estimated in the millions. All the above evidence was believed for a long time until the 21st century brought with it a new way of thinking and a new way of living that changed the game. As the 21st century rolled around, people took a new look at the problem and saw that overpopulation was not going to be as bad as previously thought. For starters, from the late 19th to the early 20th centuries, birth rates fell. Because fewer babies were being born, it first meant that the total expected number of people would decrease, which could mean less competition due to less demand, etc. This has happened because of new birth control methods other than the older ones and, because they are new. this has not been taken into account in previous studies. Since the situation envisaged above will not happen, then what will happen? Even though scientists agree that something as terrible will not happen as previously thought, they still believe that the approximate peak of 11 billion people will pose some challenges. One of these challenges will be water security. According to Live Science, “2.7 billion people currently face some degree of water scarcity in their daily lives. » (Scientific staff live). The increase in population will lead to an increase in water demand and this figure may increase. The good news is that scientists are already finding ways to make.
