Ethics behind selective breeding of animals Free Essay Example

Selective breeding, also known as artificial selection involves identifying individuals with the desired characteristics and using them to parent the next generation.

Ethical concerns and benefits of selective breeding.

Alongside the potential benefits, selective breeding of animals raises a variety of ethical concerns. There are two main concerns. These are:

Fundamental moral objections against doing something “unnatural” or, specifically to their artificial selection, for example concerns about the consequences of reduced genetic diversity.

As stated above some believe that selective breeding interferes with nature.

Selective breeding has produced livestock that gives greater yields. This has given rise to a reliable cheap food source throughout the year. It could considerably raise the standard of living in developing countries where starvation is a prevalent problem.

However some believe the development of new varieties should be allowed to take place naturally. We should accept a lower standard of living in return for natural breeding. When looking at this problem we should look at how useful the varieties will be in terms of helping humans.

Perhaps one way forward would be to allow selective breeding only in countries where it is most needed. Many people however would take the attitude that human wellbeing is more important than an animal’s welfare and selective breeding should be allowed in all circumstances as long as it can be proved that it may be beneficial to humans.

Selective breeding in pets is not as justified as selecting high yielding food animals. Most people would argue it is not acceptable to select pets for certain features that may be desirable or fashionable.

Animal rights groups will point out that while trying to improve the standard of living for humans, animal welfare is often forgotten or cast aside. For example when carrying out artificial insemination on cows and selectively breeding them to give a high supply of milk there are many cases of mastitis. Mastitis is a major source of pain for affected cows and occurs when there is inflammation of the udder and is often accompanied by lameness and infertility.

Selective breeding will lead to reduced genetic diversity. This means there will be a considerably smaller range of alleles and alleles may be lost that could be of other benefit in the future.

Many believe that we should simply be prepared to pay more for our food and stop trying to select animals which will give a cheap food source. However this solution is hardly practical in today’s economic climate and would not at all be fair to poorer countries whose people are the ones who would mostly benefit from selective breeding in the first instance.

Another issue is deciding who should choose whether selective breeding should be permissible and if so to what extent. Scientists are the people who carry out the research and explain the process to the public so perhaps they should be given the responsibility. They will after all be more informed on the whole process than anyone else. Politicians will argue they should be given the power to decide and although scientists can tell us how it is done they cannot tell us what ought to be done. Others believe the power should lie with the general public, and with society as a whole.
