Organic gardeners know that the soil matters greatly, and is also rapidly depleted. We are depleting the world's top soil quickly. We are also depleting the world's oceans. Acid rain is caused mostly by burning minerals like coal which contain some sulfur. This produces Sulfur Dioxide, which later falls to earth as acid rain.
More consumption means more energy needs to be produced.
In parts of the US this energy is most cheaply produced in ways that creates acid rain. Double the number of consumers and we double the acid rain. DDT is a very stable, very toxic chemical which was produced between the 1940's to the 1990s. But even after it was banned it was produced for another 12 years for sale in foreign countries. A jury has just been selected in what will probably be hearing the largest trial concerning a DDT cleanup ever.
