Which episode am I searching?

Question

I'm searching an episode where Lisa had to watch a deforestation (I think with Bart) at the very end. I want to know this epsiode because of the song which is played in this scene.

Answer 1

I think you are looking for "Lisa the Tree Hugger".

Answer 2

You can also try to find a song, searching by 'The Simpsons Soundtrack' or 'The Simpsons OST' requests in your search system. I usually can find the song I like in this way.
