Addendum 2 – Global Cumulative Lead Mine Production and compared to “1000 years of Carbon Dioxide”
There is a striking similarity of the shape of the following two graphs. This Model National Lead Safety Policy aims to drastically slow the rate of cumulative lead mine production (see xvii, above), and eventually stop it (see xvi, above). In turn, the reduction in lead in humans will help to reduce carbon dioxide in the atmosphere.
