A broad area of biology known as "biotechnology" uses living things and processes to create new goods that are good for people. There are uses for it in several fields, including agriculture and medicine. It takes advantage of cellular and molecular processes to create goods and technologies that aid in better human and environmental well-being.

The term "biotechnology" describes the use of biology to solve issues and create useful products. The most well-known application of biotechnology is the creation of therapeutic proteins and other medications through genetic engineering.
People have been using biological processes to enhance their quality of life for almost 10,000 years, since the earliest agricultural communities. Around 6,000 years ago, humans first used the biological processes of bacteria to produce bread, alcoholic beverages, and cheese, in addition, to preserving dairy products. But the modern definition of biotechnology, which was coined to characterise the molecular and cellular technologies that appeared in the 1960s and 1970s, excludes such procedures.
