Birds use air to allow them to fly
Clouds are moved from place to place by air
Animals need air to breathe and survive
Water is evaporated into the air causing precipitation

oil spilled into tropical ocean waters
gases released when plants make food
emissions produced by burning fossil fuels
warm water released from nuclear power plants
