In Silent Spring, how people were trying to control the nature? Explain with examples.

In the second chapter, the author explains how people are trying to take control of nature by making speedy changes to natural elements and inventing synthetic chemicals. For example, human beings have created their own source of radiation by manipulating atoms to come up with nuclear energy. Human beings have also created chemicals to control the spread of "pests," or animals assumed to be enemies of progress. Companies invest millions to billions of dollars every year to come up with a new, enhanced version of a pesticide. Although no one is against progress, the pace at which people are trying to change the environment is dangerous. The author notes that it took millions of years for the ecosystem to reach balance and enable living things to live in harmony. Nature has always found a way to make things better. The author believes that without any human interference or the application of chemicals, nature would have found a way to control crop-eating bugs and nosy house pests. The need for speedy change is destroying nature instead of making it better.
