Question

Why are scientists concerned about species loss even though extinction is a natural process?

Answer 1

The extinction of species is a natural process. Over the time, multiple species have become extinct. The process of natural selection ensures that only the most adapted species continue on the Earth. However, when the extinction rate increases then it causes a disbalance. The extinction of one species will cause a sudden rise in the species of its prey and this will cause a disruption. Therefore, the scientists are worried about the loss due to extinction even though it is natural.

Answer 2

Because, when more species start to become extinct it disrupts the balance of the earth. For instance if spiders became extinct, the numbers of insects would exponentially grow. Which will become a problem for farmers, and more diseases  would most likely  occur.
