Glaciers affect humans and physical geography in a number of ways. Glaciers are the world's largest supply of freshwater which is currently in a solid state. Glaciers are giant sheets of ice which store water in the colder months and release the water as it melts in the warmer months. This runoff of freshwater is important for plants and animal life living in the environment near glaciers. This subsequently has an impact on the human life living near by because glaciers support the eco-system and provide plant and animal life to sustain human life near them.
