the planet is constantly threatened by the presence of man. The latter has evolved over the centuries and has colonized the world, where he is a guest along with other creatures ... although it does not always seem to remember! However, today the issue of safeguarding the Earth is also addressed by global politics, even if the road ahead is still long.
Although significant steps are being taken, for example recycling and recycling, it is not enough. In fact, a Danish study recently announced that in the next 50 years the planet will witness a mass extinction of different species of animals, of such a scale that the Earth will have to take about 3 million years to recover.
The study, published in the US scientific journal PNAS, is due to the scientists of the University of Aarhus (Denmark), who calculated the speed of extinctions in proportion to the amount of time that the planet would use to restore the level of biodiversity currently present. The scholars have concluded that the Earth would need 3 to 5 million years to regain the balance of its ecosystem, returning to how it was before humans lived in an inconsiderate way, 5/7 million years ago
For their calculations, the researchers used databases containing data on already extinct animal species or which disappeared due to the spread of man on the planet. Combining the information in possession, they have predicted that in the next 50 years we will witness this mass extinction, and made simulations to hypothesize how much time nature would need to recover.
These estimates are suppositions about how things could go if man stopped destroying the environment, which is not possible to calculate at the moment. One thing is certain, scientists say, if this deterioration process does not stop in the next 20 to 100 years, the price to pay will be very high.
