Biotecnology

What is biotechnology?
-biotechnology is using living things to create products or to do tasks for human beings.
- Biotechnology is the practice of using plants, animals and micro-organisms such as bacteria, as well as biological processes - such as the ripening of fruit or the bacteria that break down compost - to some benefit.

Important of biotechnology 

biotechnology is used in in industry, medicine and agriculture to produce foods, medicines, test for diseases and remove waste.
It can also be used to solve problems and conduct research. Over time, biotechnology has formed the basis of learning about people and diseases. Biotechnology has also underpinned the development of treatments.

Disadvantages of biotechnology

(1) Loss of privacy. Medical and genetic information is more likely to be stored and shared.

(2) Discrimination. Private insurers, employers, and governmental entities are more likely to discriminate against people who have genetic or medical anomalies, especially if such information is available in databases.

(3) Cloning. Reproductive cloning could create "Frankensteins" or result in eugenic practices. Therapeutic cloning is also regarded as unethical by some groups, primarily religious organizations.

(4) Transformations of wild species. Exposure of wild species to genetically modified crops or domestic livestock could cause "super species" to evolve with resistance to pesticides, herbicides, or fungicides.

(5) Loss of biodiversity. Development of genetically modified crops or domestic livestock could reduce genetic variety among both domesticated and wild species.

(6) Harmful chemicals. Although biotechnology will generate many new and valuable chemicals, some chemicals with unknown or damaging environmental impacts are likely to be developed.
