Hey! does that mean that when I build solar plants, I can sell my mass transit and recycling center without fear? that doesn't seem right...

I don't know exactly how it's done - do any of the scenario builders here know of a way?

There are two problems with this: 1)As you correrctly stated, this feature can only be implemented for scenarios, not for regular games. 2)Even with that button turned off, nukes will still produce skulls, which if left unattended, will end in global warming.

Thanks... I gathered, from the discussion above of mass transit/solar plant et al., that industrial pollution was the problem. That button would solve it nicely. Is there a reason the rules.txt file couldn't be modified for a regular game? (I'm going to have to take a look at that file again...)

Well... aren't these two things intimately related? (more people = more tiles worked upon = more shieldpower)

This is interesting. Without going into much detail, could you please tell us which techs are these? It'd be easier

It's true that you can't sell the mass transit, since mass transit cleans up population pollution and solar plants clean up production pollution. You can sell the recycling center, though, since the solar plant cancels all production pollution from the city.

And yes, I suppose population and shield production are intimitely related. But at an extreme, a size 20 city is a size 20 city - whether it produces 5 shields or 50 makes the difference.

Maybe I should dig up the details before I post...

One I do remember for certain is that the discovery of Mass Production increases pollution - but you get the benefit of being able to build an improvement to counter it. IIRC, Industrialization, Mass Production, and one(?) other have this effect. The effects are more warning shields in the city window and a hotter beaker indicator. And yes, I suppose population and shield production are intimitely related. But at an extreme, a size 20 city is a size 20 city - whether it produces 5 shields or 50 makes the difference.

This is from memory but, if I recall correctly

Pollution bellow 20 has no effect.

Each unit of population creates 1 unit of polution.

Each sheild of production creates 1 unit of polution.

The smokestacks you see on the city menu represent pollution in excess of 20 units.

Population based Pollution is increased by Industialization , Automobile,Mass production and Plastics.

Pollution is reduced by the discovery of Recycling and Environmentalism.

Mass Transits completely elliminate pollution caused by population.

Recycling centres reduce pollution caused by production (I'm not sure by how much, but I'd guess by 20 points).

Hydro and Nuclear plants also reduce production based pollution. I'm pretty certain it's by 20 points. Based on a lot of games where I've built Hoover Dam, the only cities that require more than a Mass Transit to achieve zero pollution are the ones with more than 40 sheilds of prodution.

Solar Plants completely elliminate production based pollution, and act to counterbalance global warming.

That's my experience. My last Science City had only a few grassland shields and only ever needed Mass Transit to keep clean.

As a (very broad) generalisation, I find I need Mass Transit soon after Sewers. Before Hoover, a Factory generates pollution threats (and can Chernobyl), with Hoover it's not till I build a Manufacturing Plant that I need the Recycling Centre (but then you may need it *fast*).

You're welcome. Though I forgot to add that Superhighways increase population based pollution. I'm not sure by how much, but I'd guess 50% or so.

I build solar plants before manufacturing plants, which ensures me no pollution.

I've also experienced a rise in pollution in cities with no Mass transit in which i built solar plants.
