Should I Delevop Jungles?

[MadDjinn]

given that universities are a little weaker and science is a little harder to RA/bulb through, mid game, I like keeping the jungles around - as long as there's 4 or more in the area, or the city is a gold or science city.

I never plantation bananas. It doesn't seem effective until fertilizer, given you get 3 food/2 beakers from it early on; when you need the beakers.
