People sometimes go against the natural way, such as destroying forests, reclaiming land from the sea, hunting and killing animals.

First of all, people are destroying the ecological balance all the time, not sometimes. In less than 20 minutes on average, a species will become extinct, but human beings, on average, have 20 people born every second. With the large area of plants being cut down, countless animals will be extinct and many plants will be unable to reproduce. In the past, a vicious circle. Although nature has the ability of self-adjustment, this adjustment is limited. Once this dynamic balance is exceeded, nature can only give up human beings.
