How many African elephants were there in the past and how many are there now.

"Survival of the fittest, elimination of the unfit" is the law of elimination in nature. African elephants are actually not the overlord of grasslands. We all know that the first brother of African grassland is a lion, and the second brother is hyaena brunnea. In fact, in the whole ecosystem, all living things are a link in the food chain, except us humans. At present, our human activities have the greatest impact on the ecological balance, mostly because we humans occupy a lot of living space. Making wild animals homeless, especially African elephants, is mostly because of human hunting and the shrinking living space, which can't satisfy their lives. This is also a reason. In the final analysis, the decline in the number of African elephants is caused by human activities.

The phrase "a man is innocent, but he is guilty" is most suitable for elephants. It was born with precious ivory, and human greed directly led to its sale, so there were all kinds of killings. This is also strongly advocated by the Wildlife Conservation Association. As long as we unite and resist buying and selling, this kind of killing will be reduced and the ecology will be better.

From the point of view of human activities, the decrease in the number of elephants is the reason. In fact, the change of species in nature is not that simple, just as we can't know how dinosaurs disappeared, the change of nature has a greater impact on species. We know about the forest fires in Australia, but we don't know how many species will disappear, and we don't know why dinosaurs died out. According to our present strength, it should be difficult to do it. The only reason should be the change of environment, which has been unable to adapt to their survival. The simplest thing is that climate change and changes in the number of plants can directly lead to changes in the population of herbivorous dinosaurs, and also lead to the reduction of the population of herbivorous dinosaurs due to lack of food until they become extinct.

The same is true of African elephants. Human activities on the grassland are more and more intensive, and the area of activities is getting smaller and smaller. The shortage of food and human killing are the direct reasons for the decline of elephant population.

In the process of ecological destruction and restoration, a large number of species will disappear, whether plants or animals, in fact, nature and even microorganisms and insects will undergo great changes, which are imperceptible to us ordinary people, but for biologists, these are all members of the big family of nature and are indispensable. Each plays a role in its own position. Without any one, the whole ecology of nature will be affected.

Excessive use of pesticides, fertilizers and herbicides in biochemical drugs will cause great changes to the environment. The initial impact is not obvious, but the flora and insects in the soil are affected, and then the microbial decomposition in the soil will disappear. Our most common dung beetles is actually the best partner, which is rare now. They used to decompose the feces of wild animals on the grassland.

"Think twice before you act", for us humans, we should think clearly before doing every action. The impact it brings will eventually be reflected in ourselves, and some may be future generations. Just like we used to kill wolves on the grassland, it seemed to protect the herdsmen's cattle and sheep, but in fact we lost the patron saint of the grassland. Grassland wolves are active in the grassland. They can eliminate the old, the weak and the sick among the five livestock on the grassland and keep the grassland population clean. We must use a lot of feed and antibiotics to feed cattle and sheep now, just to make them healthier, which was unnecessary in the past. Complaining that you can't guarantee food safety is actually suffering from your own mistakes.

From this perspective, in fact, our human activities are still very important for population control. The invasion of exotic species, such as Australian rabbits, generally has no natural enemies, which directly leads to flooding. However, crayfish and crabs that invaded China were almost eaten by us as "endangered protected animals" because of cannibalism. Of course, this is a joke, but we can't ignore the great energy brought by daily activities. Do not underestimate us.

"Illness from the mouth" Many of our human diseases are eaten, and many behaviors are hurting ourselves while hurting wild animals. The disease from the mouth is the inculcation of the ancients, and we should not forget it.

For the current African elephants, the shrinking living space and human hunting are the reasons for the decrease. Fortunately, we humans have begun to realize this problem, and more and more people have begun to join the wildlife protection work. I believe that when more and more people join in, not only elephants, but also other wild animals will be loved and protected, and we will get enough living space to live in harmony with us.
