Yeah, everyone is educated eventually, while in real life some people either just can't make it to high level diploma, or want money fast and go to work instead! Into a bakery / forestry or something. Or maybe they are in low residential caffees selling caffee...

In any case, there could be more scientific forestry, too. Not just tree farms etc.

Though, I guess reprocessing the woods causes pollution, which is more about the normal industry...

Yes, I tried forestry too, but huge "not enough workers" everywhere. But I will increase high density buildings somewhere a lot, and tune down new forest industry zones for now.
