Pollution is a resource that is created as a by-product of building, industry, some weapons and the general day-to-day waste produced by a Culture. It takes up space and has a detrimental effect on health, tourism and general quality of life if it is not stored in the appropriate place (dump-type buildings such as the landfill dump) or destroyed entirely by some other method. The age-old adage of 'out of sight, out of mind' will work as well.
