In the Futurama episode "Mars University" the Professor implies that there are no jungles on Earth.

Fry: Wow! The jungles on Mars look just like the jungles on Earth!

Professor: Jungles? On Earth? (wheezing, old man laughter)

But, in the episode "Debate 3012", while Fry, Leela, and Bender are going to Chris Traver's birthplace, they are making their way through what looks to be a jungle. Leela slices through the vegetation with a large knife in both episodes.

Also, if there are no jungles on Earth, why? Is it due to pollution, dehydration, deforestation? Anything?

I don't know if jungles appear in any other episodes, or if it's just a rainforest, but I just noticed this a few days ago.

    The writers make it a sport to contradict themselves as much as possible (yes, intentionally!), so it's really hard to come up with definite statements about mostly anything.

  • Don't have enough material yet. Noting that in S04E13, Bender used a fake jungle[Congo] disease to get out of marrying Calculon.

  • Yeah, I suppose the Congo disease that both Bender and Calculon act out is also a dead give away. Mar 13, 2013 at 18:14

This continuity error can be resolved by simply assuming that a jungle has been transplanted from Mars to Earth in the eleven years between those two episodes. The Congo is also a state (two, actually), not just a jungle, so the disease mentioned in that episode need not be jungle-related.

As for the reasons behind the jungles disappearing, deforestation, global warming and nuclear winter are all mentioned as having occurred in the first Christmas episode (Xmas Story), which also reveals the extinction of pine trees (along with poodles, which are seen in the episode The Mutants are Revolting). It seems likely that one of these disasters also caused the extinction of Earth's jungles, though it's never noted which of these disasters, if any, are responsible.
