A lot of people may have heard about plants being genetically modified in order to serve a greater purpose, one being able to grow more disease resistant strains or a substantially increased harvest.
There are now a number of genetically modified plants being used today in farms looking for better harvests and more robust plants. There’s the genetically modified tomato that has already been made available with such characteristics as having larger fruits as well as a longer shelf-life.
Genetic modification has gone a long way with still a lot to strive for. One of genetic engineering’s long-standing dream is to be able to clone humans in the near future. Human clones are different from ordinary humans in that they are not produced through natural sexual means.
Human clones can be created right at the laboratory by just manipulating genes, modifying them and growing them in test tubes until they form into fully grown humans. As of yet, human cloning might still remain as a genetic scientist’s dream since no process has yet been discovered that will be able to successfully engineer human genes and chromosomes and grow them in a laboratory. But the future for them looks hopeful.
A while back, a breakthrough has been made in gene cloning in that an animal has been successfully cloned right from the genes of a mother sheep. Surely you might have heard of Dolly, the first ever human cloned sheep. This breakthrough may have given genetic scientists with additional knowledge that will further help them advance the technology needed to eventually clone humans.
Although human cloning may be such an exciting subject for many people, most especially a large number of genetic scientists, still questions and doubts abound as to how such advances would work to the good of the whole humankind. There are people who question the ethics behind such endeavors. There are people who fear that human cloning may be the last straw when it comes to tinkering with the natural balance of things.
The risks involved when compared to the purported benefits have not yet been specifically drawn. An air of excitement as well as that of apprehension go hand in hand when it comes to the subject of human cloning. A careful and deliberate contemplation of such a sensitive subject might be needed.
Continuous healthy debate by both sides will help a lot in trying to get over the controversy that surrounds human cloning. All these should be done before any form of human cloning is to be advanced in the near future as one of the most amazing breakthroughs and discoveries for the whole humankind.
