November Reading: Chapters 4, 5 & 6

For the month of November we will be reading and discussing the threats posed to our natural systems including erosion, water shortages and desertification as well as the direct impact of climate change on human beings. The economic divide, life expectancy, disease and malnutrition all take their toll on a already stressed planet and human society.

Don Reicosky, a Soils Scientist from the USDA Soils Lab, will be presenting his perspective on the threat posed to soil, perhaps the most valuable resource any country has.

The average depth of topsoil is a relatively thin six inches deep and was formed over long stretches of geologic time. A third of all cropland is losing topsoil faster than new topsoil can form. Why? And what can be done about it?

Hope to see you on Thursday, November 13 at 7:00 p.m. in the Briggs Library McGinnis for a lively discussion. Social time begins at 6:30 p.m.
