I think all human of all nations should stop killing endangered species.
I went to the museum of zoology the other day. I saw a dodo bird (just the core of it of course since it's already extinct) and I thought what a pity they killed them all.
The coalescence of human abusage and introduced breeds greatly, shortened dodo populations. Within 100 years of the arrival of humans on Mauritius, the once plentiful dodo was a sparse bird. The final one was succumbed in 1681.
Please don't let this happen to whales.
