I like the idea that we can build recycling centers to hold down pollution, but we don't see any other alternatives to hold back pollution. I would like to propose the addition of Hemp; obtained by an additional upgrade to the current 10 farms policy.
For example, the 11th through the 20th Farm upgrade will be at a higher cost, the Hemp farms would reduce pollution in a city by 15 or 30 points each as this reflects real life data that Hemp processes more CO2 than most other plants.
I also like the idea of Hemp farms producing Oil to refine. IRL you can take Hemp-Seed oil and pour it into a diesel engine, it will run.
I want a pollution solution but i also know if we add Hemp we might as well make it a little more realistic and have farms produce something. Oil is realistic.
