Wolves do fairly well without humans, bees as well. Which animals did we bring back from the brink of extinction? I'll admit that new subspecies have emerged thanks to humans, but we hardly need to keep e.g. 1.3 billion cows (https://en.wikipedia.org/wiki/Cattle#Population) just to save the species from extinction.
Buffalos are a good example. Red Panda as well if I'm not mistaken.
The sad part is, we've also made species extinct just because they weren't tasty. Dodos for instance. Taste bad, so we just killed them for fun. Then they went extinct.
