Climate Change Chronicles

Cars in traffic

Most cars and trucks burn fossil fuels, which produce carbon dioxide and contribute to climate change.

Freshwater makes up just a tiny percent of the water on Earth. Yet we depend on it for everything from growing food to manufacturing to everyday uses at home. The averge American uses 340 liters (90 gallons) per day.
