Pollution effects & Green technologies

To make the game more challenging I suggest to implement a full pollution feature:

In general creating pollution for long period of times may cause major (destructive) effects wich may "force" the player to consider more eco friendly way to go ahead of face a very challenging island:

- Air pollution affect citizens (already in game)
- Air pollution over an X ammount may create polluted rainfalls (with extra negative effects on pops)
- Polluted rainfalls may damage crops & underground water reserves (maybe with polluted water?)
- Co2 dumped into the atmosphere should have a counter to trigger some events (?)
- Implementation of all alternatives to create power/products with minimal amount of coal/oil - Alternatives to plastic (?) From crops ?
- Option to recycle plastic (?)
-Ground pollution for heavy polluting industry (?)
- Implementation of Green power (new solar panels/power plant & eolic (wind turbines) should be in game

Ive been short due to the character limit.
