If there are only 1 male and 1 female left on the earth, how long will it take to multiply to 7.6 billion people? The answer is cruel

Once the population growth rate slows down, effective countermeasures must be taken and the focus will begin to shift. If we remain indifferent, the consequences will be disastrous. India is the representative.

Which species will be inscribed on the last gravestone in the world's extinct animal cemetery?
Throughout the history of the development of the universe, we find that the extinction of a species is not a rare event. In the long history of the past 450 million years, the earth has experienced five historical periods in which the species and number of organisms have declined sharply. These events are called "five mass extinctions". The most famous is the fifth extinction, 96% of marine life and 75% of land life suffered mass extinction, including the dinosaurs that dominated the world for 140 million years. Due to the extinction of dinosaurs, mammals also began to multiply, and primitive humans began to multiply.
