I love talking about GM - and to be honest I am not dead set for or against, just interested in the debate. I can see arguments for both sides, and having completed a biotechnology module as part of my degree, I was well versed in every side of it. Having said that, I will not wave my hand around and say that I know what I am talking about - GM is such a varied area it would be impossible for any one person to fully understand it.
My lecturer for GM, compares it to those plant breeders who have been 'selecting' certain traits for generations. He argues that by doing this, without the use of a lab and certain screening techniques, has opened people up to greater dangers. However, by swapping traits between individuals in a lab, is termed as GM, and although being safer (as it is monitored from start to finish) it is frowned upon.
However, his argument breaks down when you start to think that they are implanting anti-freeze genes from arctic fish, into plants in an effort to make them frost resistant. That cross could never be made 'naturally' and only in a lab environment.
So is it right or wrong? If, by creating drought/frost resistant varieties, we can help third world nations to establish an economy, to feed their own people rather than rely on aid, surely that is a good thing?
But is interfering with nature really ever a good thing? Should we argue against genetically engineering plants and animals just to benefit the human race? Do people argue that everything should be left in a natural state? If that is the case, surely those people would also argue that premature babies should be kept off life support, that life-saving drugs (that have been developed in a lab) should be withdrawn, that gene therepy that is helping millions of children with genetic disorders (such as cystic fibrosis) should be halted, as that too is a form of genetic modification and manipulation.
I worked at Tesco many years ago to pay my way through uni, and would laugh at the amount of people who would fill their shopping trollies with organic products, then head to the cigarette kiosk to purchase tobacco. The reason I laughed is that almost all tobacco (something like 95%) is Genetically Modified. What about the sheets we sleep on and the clothes that we wear - most cotton is GM. Is it ok as long as we do not eat it?
Curely the biggest argument against GM is not its safety to be eaten (as there are so many test and trials most risk is eliminated) it is whether it is safe to be grown, where there is potential for the gene technology to escape into the wild population.
Its certainly an interesting debate, and one that will rage for many years I am sure.
