>> but i think we have been geneticaly altering things for thousands of years now dogs horses
>> crops nearly everything we eat has been altered by man
The main difference is that if left to nature these things would return to their original form ... dogs back to wolves etc. GM foods are modified in a totally different way to sheep. As Merrick points out, attaining goals by selective breeding is very different to genetic modification in one generation.
Also:
>> dogs horses crops nearly everything we eat
That really does read as if your diet consists of mainly dogs, horses and crops :-)
