i think we should let nature run it's course... i mean the philosophy of "survivial of the fittest" definitely comes into play here. i dont think we should try to unnaturally breed species... that just leads to ethical and moral questions.... like should we play god and try to change the effects of natural reproduction?
we should focus our energy on trying to PREVENT animals from going into extinction rather than trying to save the last ten birds of a species...
as humans we should try our best to not destroy the ecosystems around us...
that is what we SHOULD do, but can it ever happen? we are all greedy and we all desire a luxurious lifestyle... not often to we really consider what impact we have on the other organisms that we share this planet with.
