According to the world census, in 2012, there were seven billion people on planet Earth. Currently, the population weight is relatively close to 300 million tonnes. The seven billion contribute to a world that is constantly evolving technologically, medically, socially and economically. Unfortunately, having such luxuries at our fingertips, it's only natural to take things like electricity and even water for granted. We don't look at what will happen in the long term because everyone uses these things as they want. In some places, birth rates are very high, such as Africa, which has the highest birth rates in the world, mainly due to lack of knowledge about family planning and awareness of safe sex. Interestingly, the growth of six to seven billion people has actually slowed down a bit, but that doesn't mean it won't pick up again, perhaps very soon. And that being said, some argue that overpopulation and excessive depletion of natural resources will no longer be a major problem in the future. But the biggest question we seem to face is whether humanity really wants to take this risk, according to the few journalists and scientists who say so? To succeed, we will need to take various precautions and measures to preserve our natural resources that we rely on, such as providing incentives or rewards to families to prevent our population from reaching numbers that we cannot control or maintain. The number of children women need to maintain a reasonable and manageable population is 2.1 live births per woman. Currently, many countries, including the United States, exceed this level of sustainability. On the contrary, in many European countries the birth rate is falling.
