Biotechnology aims to benefit society
- The fundamental aim of biotechnology is to meet human needs or demands in order to improve our quality of life.
Ancient biotechnologies mainly aimed to provide a more reliable food source by growing plants and domesticating animals rather than depending on hunting and gathering. Over the last century, the number and range of biotechnologies have rapidly increased. A key to this increase was the discovery of the structure of DNA in 1953, leading to numerous applications, particularly in forensics, medicine and agriculture.
Biotechnology impacts depend on many factors
As our knowledge and capability in biotechnology increases, so do the potential benefits. However, while the intention behind new biotechnologies is to benefit society, determining what impact a particular biotechnology may have is complex.
You need to consider a number of interacting factors:
- Issues specific to a particular biotechnology
Different biotechnologies have different issues to consider
- People’s different needs and values
People’s needs, values and priorities vary, leading to differing views of how a particular biotechnology may impact on them.
Some people hold strong moral and ethical views on particular practices based on their religious and cultural beliefs. Biotechnologies involving practices such as organ transplants, manipulating human embryos and using animals in research may be particularly offensive to some groups of people. Their views are likely to affect progress and availability of some biotechnologies in different societies.
Different countries have different needs and priorities. This affects what biotechnologies are developed or accessible in those countries. For example, New Zealand has the highest incidence of melanoma in the world, so developing a melanoma vaccine is a higher priority here than in other countries.
Biotechnologies are developed in response to society’s needs and demands at that particular time. People are often reluctant to accept new biotechnologies initially, but over time, they tend to become more widely accepted.
New biotechnologies are often controversial
Biotechnology developments are often controversial because of the ethical issues they raise. They frequently become the subject of public debate. Sometimes, people are wary of new biotechnologies because they involve doing things that haven’t been done before, and they are unsure of possible future effects. Public debate raises the issues and presents different viewpoints. This can help people make informed decisions and also influence government organisations that control new research and development.
