However, I did a soil study in 1995 which corroborates everything in the article. I never figured out "peak soil", except to know that by 1995 the world soil study done in 1910 showed an average of 15" of soil and we were at, then, an average of 5". That was only part of it, so much soil was depleting in other ways, too. I calculated that business as usual would have the planet out of all but "oases" of arable land by 2140. However, by 2050, soil degradation will lower crop yields 10 to 20% in its part of the overall decline in yields of 35-50%.
It is probably one of the easier human problems to correct faster than nature. Large scale composting and a complete change in how we take care of our organic wastes and even dead bodies is needed to compost and rebuild the world's soils.
I think it was Chief Seattle who said "we walk on the faces of future generations."
Great article and we must always realize that we need healthy soil, air, water, and climate to survive and for those in the future to survive. We also need a wide variety of healthy ecosystems to survive. Ignorance of these things is also one of mankind's biggest problems.
