Answer: It's an opinion because it is a belief based on the perspective that the government should be involved in stopping the extinction of animals.
This statement is an opinion because it arises from the belief that government intervention is needed in order to protect the environment. Other people might have arguments that go against government intervention, and these arguments might be logical and supported with evidence as well. No amount of facts can definitely prove the value of either one of these positions. Therefore, this is an opinion, as opposed to a fact.
