There seems to be a lot of information qualifying pollution in this article without the accompanying statistics or estimates of local and global production and accumilation of specific pollutants. I came to this page in search of a metric or statistic for annual by-country production of pollutants, or a survey of the accumilation per-pollutant. These would be good statistics to include.

In the event these statistics do not exist compiled, what is the policy on extrapolating information from other wikipedia articles to include on an article? This article notes that pollution increased dramatically in response to smelting and refining activities, and though I might not have easy access to all the pollution information, I can find or extrapolate information for global and per country ore refining and metal recycling practices, their energy use, carbon footprint, what pollutants they emit and in what quantity. It would be nice to get the big picture in this article which would quantify the activities of man in terms of pollution instead of just 'pollution: history and molecules' -RR — Preceding unsigned comment added by RotogenRay ( talk • contribs) 18:48, 5 May 2014 (UTC)
