I would not worry about that for now. Less than 800 million people inhabited the Earth in the mid-eighteenth century, and today, just 250 years later, we are more than 7,500 million and we will continue to grow until 2050, at which point forecasts indicate that the world population will stabilize. What does this constant growth mean? Several direct consequences such as the depletion of natural resources due to the unequal and excessive consumption of resources. The planet has a limited capacity to generate raw material and each year the deficit of natural resources - consumption of these resources at a faster rate than the planet is capable of generating them - arrives earlier. As a consequence, in developing countries, overpopulation exerts an excessive pressure for control of resources. Territorial conflicts over water supply are in many cases leading to geopolitical tensions that could lead to wars.
Another important consequence to take into account is the degradation of the environment as the excessive consumption of natural resources as well as the growth of energy production from coal, oil and natural gas (fossil fuels) is having a negative impact, on the one hand, consequences such as deforestation and desertification, disappearance of animal and plant species, changes in the water cycle... to which is added the most direct consequence of the emission of large amounts of greenhouse gases, global warming.

To which I conclude that I am not against reducing a little the number of births, since there are few resources, shortage of water, accumulation of many people in a limited space and lack of money, which causes an increase in the cost of life where only a percentage of the population can cover all their needs. Overpopulation is, therefore, one of the greatest challenges that humanity faces and that threatens the future of the entire planet in economic terms , environmental and social.
