Answer:

Step-by-step explanation:
In the active voice (the voice the sentence is currently in), the subject performs the verb. It puts the subject in the beginning.
- Basically: "the subject does something"
In the passive voice, the subject receives the action from the verb. The subject is placed at the end of the sentence.
- Basically: "something is done by the subject"
The sentence is currently: People are destroying the jungle.
To convert it to passive: The jungle is being destroyed by people, or just, the jungle is being destroyed.
