Most of the achievements of biotechnologists have become useful and even irreplaceable in many areas of human activity. Here are some examples. The pharmaceutical industry uses GM strains that produce antibiotics and other medicines. Agriculture uses transgenic animals and plants that are highly productive, resistant to pesticides, aggressive environmental factors, and various ailments.
