Is the following parallel structure? “Deforestation is one of the leading causes of climate change, species extinction, and habitat loss.”

Yes.

Explanation:

Parallel structure is when you connect multiple ideas into a list. We do have a list here is the sentence: “Deforestation is one of the leading causes of climate change, species extinction, and habitat loss.” You are using the same way to put multiple items in a list.

It is listing off the things that deforestation leads to. So, it is parallel structure.
