GMO's ... check for bias in the articles/videos
Genetic modification (GM) is the alteration of the genome of a plant or animal by the addition of new genetic material. It underlies the concept of transgenics, in which an organism is modified to incorporate new genes that lead to new characteristics, such as the production of proteins for human health, or the expression of a gene for herbicide resistance in plants, to name just two applications.
The difference between GM and selective breeding.
Selective breeding is a form of genetic modification which doesn’t involve the addition of any foreign genetic material (DNA) into the organism. Rather, it is the conscious selection for desirable traits. Pro-GM campaigners argue that humans have been ‘genetically modifying’ organisms for thousands of years, albeit without knowledge that the favourable traits they were selecting for were determined by genes. For example, humans have always selected cows with the highest milk yield and bred from these to produce herds with good milk production. A chance mutant grape with no seeds was bred to produce seedless grapes now available in our shops and supermarkets.

So ... is the concern about manipulating genetics via breeding selected traits within a species OR transgenics where genes are taken from different species and the DNA sequence altered?
