@pleonasm - I'm sorry, but I think conservation ethos should still apply, even if it interrupts local hunting traditions. If the animal in question goes extinct then that is going to interrupt their ability to hunt even more.
And it is terrible that some other people are the ones responsible, but that doesn't mean they should completely ignore the problem.
What I think should be taken from this is that there need to be solutions for conservation of endangered animals that take into account the traditions and needs of the people who live in the area as well. If they would normally be eating those animals, they need something to replace that in their diet. If hunting is their usual activity then maybe they can replace that with activities that will aid in conservation, like tracking animals or repelling poachers.
People are flexible, usually much more than ecologies are. They just need to be included in the solution.
