Endanger vs trouble?

[Christin93]

We can both use these words, but What is the difference? capital worlds are the ones I think are right

Tigers are ENDANGERED/ troubled animals by the loss of habitat and illegal hunting.

Thanks in advance!

They mean different things. It's not clear what you mean by 'We can both use these words'; do you mean we can use them both? You're right to prefer 'endangered' in this context.
