“We’re treating soil like dirt. It’s a fatal mistake, as our lives depend on it.”

2) Click on the photo below and read the article from the WWF about soil erosion and degradation.

The photo is from Lake Bogoria, Kenya

Large scale erosion forming a gully system around six metres deep. The cause of the erosion is over grazing due to goats and other livestock. The exposed bare earth is washed away forming the gully system. Deforestation in the Lake Bogoria area is a serious threat as it leads to a drop in the water table and therefore streams and swamps drying out. Lake Bogoria, Kenya.
