Save Soil

Soil degradation is a global phenomenon. 40% of the soil is already degraded. By 2050 about 87% of fertile soil will be degraded and the population of our planet will be 9 billion by then. The result will be huge shortages of food starvation and migration. Worse still bringing back its original level of fertility takes around 15–20 years. The only way to avoid such a disaster is to save the soil. This book explains why soil degradation occurs and how to prevent it.
