incorrect, use natural order (therefore, cloning is morally wrong)
correct or incorrect? cloning reduces individuality. cloning is the process where an organisms' dna can be replicates and turned into a new organism. therefore, cloning is morally wrong. reducing individuality is morally wrong.

correct or incorrect? using snare traps to kill the feral pigs will hurt them. so it is wrong to use snare traps to kill feral pigs.
incorrect, use consistent terms (transgenics)
correct or incorrect? genetic engineering is the process in which an organisms' genetic material is manipulated in some way. gene manipulation can be a very dangerous process. when we transfer genes between species, we may cause damage that cannot be repaired. transgenics is therefore not a good thing.
