The global vertebrate population has decreased by an average of 68%. What is the reason?

Due to human destruction of the environment, the number of species in the world has decreased. Without humans, these animals would still live well on the earth.

0 1, the global vertebrate population decreased by 68% on average. 65438+1October 4th is the Global Animal Day. The main purpose of setting up this is to let people know the importance of protecting animals. As early as September this year, WWF announced that the number of vertebrate species in the world has decreased by 68% in the past half century. Let's give a very simple example. If an animal has 10000 population, and now 68% of the population has disappeared, then there are only 3200, which may seem to be a lot, but what if it is used on animals with small populations? Originally, there were only 10 animals left in the world, but later it was reduced by 68%. In other words, there are only three kinds of animals left in the world.

We should all know something about lonely George. George's death marked the extinction of the Galapagos elephant turtle.

02. Why have their numbers dropped so much? Why has the number of wild animals dropped so much? The reason is still to be found in us humans. With the development of science and technology and the progress of the times, more and more animal habitats have been destroyed. This phenomenon is not common in many developed countries, but it is very common for developing countries in South America and Africa, and the policy of exchanging environment for economic development is very common.

Take Brazil for example, we should all know it's called? Lung of the earth? A considerable part of the Amazon jungle is in Brazil, but due to the poor economic development in Brazil, people living in the jungle began to destroy forests and reclaim wasteland, and villages and cities appeared in the rainforest. Since 1970s, the Amazon rainforest has disappeared by at least 20% due to human destruction. If we continue to destroy it like this, the Amazon rainforest is likely to disappear by the end of this century. More crucially, with the disappearance of the Amazon rainforest, a considerable number of animal populations will be directly extinct. You know, the environment of the Amazon rainforest breeds 50% of the biological species in the world.

Summary: The earth is the only home for human beings, and it needs the common protection of all of us, otherwise the population that will disappear in the future will be us.
