How about making jungle return your city 5 shields? Anyone who's been in a jungle knows it's not all creepers and soft banana trees ... there are some pretty useful woods just like with forests. (Not to mention rare beasts the Chinese civ might be prone to purchase from you before the Viagra advance is discovered ...

As it is, jungles take tons of time to clear (much more than forests, which isn't all that realistic) ... for absolutely no return, other than to create arable or minable land. In fact, jungles uncleared should have some food and/or shield value, just as forests do ...
I don't propose they simply be made into forests -- that would be pretty stupid. But they shouldn't be the useless annoyances they are now, either.
I also vote for the ability to lumberjack, but agree that you can't "rush" a forest to growth with stacks of workers. An additional thing with jungles that might make up for giving them some extra value ... if a former jungle tile has one jungle tile bordering it and no citizen working it, after 20 turns it "reverts" to jungle (similar to fungus growth in SMAC, and pretty close to what really happens, notwithstanding the disjoint between passage of time in CIV3 and reality). If the tile has two jungle tiles bordering it, 15 turns ... etc. etc.
Also, negative environmental effect of clearing jungles/forests ... depends. Perhaps the map generator notes the percentage of land covered in jungle/forest at the beginning of the game, and rates this as 200% (or something) needed for optimal ecological balance (for O2 production, etc). If civs proceed to cut/clear jungle/forests down to below 100% optimal balance, negative effects start to be felt. Should we then be able to enter into ecological pacts with other civs, where we each devote a set number of workers to re-seeded forests/re-planting jungle? Could be interesting, especially for "peaceful builder" types ...
Last thing -- has anybody mentioned friendly fire? Small chance that bombardments will kill your own troops if they are in tile adjacent to bombarded tile?
Also, apologies if this stuff has been mentioned before, or dealt with in various patches. I play on a Mac with an out-of-the-box version purchased very recently, so I'm not sure which game changes from the original PC version were included in that. I don't seem to be able to lumberjack, if that's any clue. I would like to, however ...
