While some parts of the United States struggle with drought, others are faced with more water than they know what to do with. Minnesota reconstructs roads and drainage systems in order to be more prepared for the large amounts of rain fall they have received, largely due to climate change.

The result is greater cattle productivity and a more eco-friendly farming system.

In India, 620 million people openly defecate outdoors, causing harm to hygiene, sanitation, food, and water resources.
