ScienceDaily (2011-02-09) — Soil depletion hastened the collapse of at least one society,
the Greeks, and contributed to economic hardship as recently as the last century in the
Great Plains of the United States. With climate change and population growth affecting
the services provided by soil, a team of scientists say more attention should be paid to
protecting and rejuvenating soil. Strategies for doing so include refocusing and boosting
research, and communicating its importance to the public.
