Number hey? How do you know they are endangered? Got any more silly stats on that? Done an entire environmental science and biology degree on this stuff, heard all the arguments with lots of stats and other crap, don't buy it. People are dying, thats it.
You still don't see the effect of emotional arguments like that?
A analogy can be drawn with the poor people arriving by leaky boats to our shore. You can throw all sorts of stats around, they cost the taxpayer so much, they will come here and take our jobs, they are risking their lives etc etc. then I made friends with someone who came by boat and listened and learned of his personal story. It changes your 'rationale' arguments if there is such a thing. Sit down with one of the families who has lost someone to a shark and spit our your stats and philosopihical hug a tree and save the gay whale bollocks and look them in the eye.
Just saying there is a personal story/s here that to me overrides the protection of an ecosystem that is already / maybe out of balance. Sorry don't have any stats for you.
