In my world I have the canola press, fermenting barrel and oil generator along with some solar panels from actually additions, with pollution filters against everything actually additions except for the atomic reconstructor. I also have a metallurgic infuser, coffee maker and two furnaces all with filters on them.
We have so many trees you can't even see the sky around and on top of our house and the animal farms are in a different chunk, yet pollution continues skyrocketing into acid rain territory unless I have several advanced filters running.
Do leaves do anything? I have so many trees saplings won't grow in the area anymore because there's just no space, I ended up having to /addPollution to get it down to reasonable levels. Do trees not do anything once they're up?

HI!

I think this may be an unintended interaction between Actually Additions and EcologyMod.
I noticed my villages were going Chernobyl really fast without interaction from myself.

I think the ActuallyAdditions machines when paused (mid operation) still count as running, and increment the pollution as if they were constantly on. Try removing those machines for a while and see if the pollution drops?

Hope you find a solution!
