When humans do anything to an animal or plant species, we are encouraging the development of traits we want and discouraging traits we don't want. This changes the species. For an example, look at how food crops are different from their originals.

So decide how you feel about this process.

humans are culling sharks...I'm against that, but the thing is that they're not killing ALL the sharks, just the ones that are 3m and over, the rest are considered harmless...so now I got nothing to backup my point considering the fact that sharks aren't going to be extinct. so should I still be against shark culling or? thanks!
