Every sphere of life has been revolutionised by science. There have been innumerable inventions. One of the greatest inventions is the invention of medicines. There has been a series of tests carried out using animals as subjects and various medicines have been tried out on these animals to check their efficacy. Once these medicines are found safe for animals, they are used for human beings too. Earlier, diseases such as cholera, plague and smallpox used to wipe out entire populations. Today, these diseases are under control due to the wonder drugs invented by scientists. Science has also contributed greatly to agriculture. The use of fertilizers, pesticides and scientific methods of cultivation has helped to increase the yield per acre.
