Delegates from the United Nations’ convention on Biological Diversity have defined biotechnology as ‘any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for a specific use’.

Biotech has applications in four main areas: health care, agriculture and crop production, the production of biofules and oils from corps and environmental uses.

The environmental uses of biotech include recycling materials, treating various waste products and clearing sites that have become polluted by industrial activities (known as bioremediation).

Medical uses of biotech can include engineering and utilising organisms that can produce antibiotics or genetic manipulation of genes to artificially cure certain diseases. Technologies applied to medical applications are known as ‘red biotechnology’.

‘Green biotechnology’ are those applications directed towards farming and agricultural solutions. An example of this technology is devising crops that are resistant to infection; meaning agricultural chemicals such as pesticides do not need to be used.

Geneticists argue that this is a more environmentally friendly approach than solutions from traditional farming practices (although this is aggressively contested).

Continuing the colour theme, ‘white biotech’ are those technologies utilised by industry. Industry can use organisms that have been specifically designed to either produce useful chemicals or to destroy hazardous chemicals that may otherwise pollute the environment.

The final application is in marine or aquatic applications (known as blue technology), however examples of use of biotechnology in this field are comparatively rare.

Within medicine, biotechnology can be utilised for drug production or gene therapy. Traditionally the pharmaceutical industry develop new medications predominantly through trial and error. There are more and more anti aging breakthroughs being reported almost on a daily basis while some treatments such as hgh supplements are proving to be quite controversial.

The modern biotech approach is to use proteins to target the underlying pathways of the illness. For example, microorganisms such as E. Coli or yeast can be used to produce insulin, treating the underlying cause of diabetes, or can be used to produce antibiotics.

Another advantage is that the use of modern biotechnological techniques allows for drugs to be produced more quickly, efficiently and cheaply.

For example, before biological organisms were utilised to directly produce insulin, it had to be extracted from sheep or pigs, which was a very expensive, and time consuming procedure that also often resulted in unwanted allergic reactions in the patients. Using genetically altered bacterium allows for the production of huge quantities of human insulin at a very low cost.

Gene therapy is a new biological technology that aims to treat or cure both genetic and acquired diseases such as AIDS or cancer by using normal genes to supplement or replace defective genes, or to induce normal functioning (of the immune system for example).

Various ethical issues arise from the use of new biotechnologies within the medical sphere. New technologies may be able to effectively diagnose a range of diseases, but if these diseases have no effective treatment or cure, then a pertinent dilemma is raised for medical practitioners.

With the use of germline therapy, the genetic makeup of individuals’ descendants can be changed permanently; therefore any error in the procedure will have impacts upon several future generations of the family. Bioethicists have also raised the ethical integrity of technologies that could be used to produce designer babies.
