the Work of our hands
Humans have been good at modifying the Earth to meeting increasing demands. Populations have doubled while food production has increased by two-and-a-half times. The gains achieved through this transformation of the land have not been without costs. Each year more than 25 million acres of cropland are debased or lost as rain and wind sweep away topsoil. The spread of urban centers also contribute to a loss of fertile ground.
This video discusses the relationship between societies and agriculture, historically and today. Why is it that despite our best intentions, many of the world's productive landscapes are in trouble?
