Add the commas mentioned above, change “with” to “by,” and you’re done.

I would use “by” instead of “with”. “I can’t find the answer because I don’t think there’s anything wrong with the sentence”. This is how you say what you wanted correctly. Have a great day and schedule a class if you ever want to practice one on one.

Hi Liz! It is “threatened by poaching” not “with”. The phrasal verb / expression is “to be threatened BY someone/something”. Hope that helps.

Hello Liz - as a native speaker I'm afraid like you I find this sentence to be fine. "By" does sound better than "with" for the reason Marlene says here, but I certainly wouldn't say "with" is wrong. For example, it's actually far more common, I think, to hear "threatened with extinction" than "threatened by extinction", so the rule which Marlene rightly describes must have exceptions. I'm struggling to think why "threatened with extinction" is fine but "threatened with poaching" sounds strange; perhaps it's that distinction between poaching being a deliberate human act and extinction only being a general consequence of it. But that would be the opposite of the rule. Argh! Very difficult.

This is a tough one, I have to admit.
