I normally talk about the crops and agriculture side of genetic modification, because that's what interests me. However a few months ago I watched a program on the BBC about the ethics involved in genetics and I saw something really interesting.
There's a farm at Utah State University that has a rather extraordinary goat. The goat has had a gene transplanted into it which means that it's milk contains an extra protein, which is extracted and spun into spider silk.
Spider silk is one of the strongest materials known to man,weight for weight it's stronger than steel. Do you think it's ethical to modify goats to produce this extra protein? The goats are treated extremely well at this farm, better than most farmed goats. Is this ethical?
