Many people think that Natural Sciences are very important in our life. But some people do not support this opinion. Nevertheless, I agree that Biology plays an important role. Biologists are studying nature, the laws of nature, and the structure of various organisms. It is closely associated with many sciences and human activities.
The data of biology helps us to understand the laws of nature, predict the development of life on our planet, and define the role of people in its preservation.
A lack of knowledge or disregard of the laws of Biology leads to severe consequences for the environment and for human beings. Now the preservation of the world depends on our behavior.
