Glacier transport material as they move, and they also sculp the land beneath them. The landscape can be drastically reshaped by the force of a glaciers weight combined with its gradual movement. The ice erodes the land debris far away. Over hundreds of years, the ice totally changes the landscape.
Glaciers are often major tourist attractions.
But they also affect people in a more direct way. In La Paz, Bolivia, people rely on glacial melting from a nearby ice cap to provide drinking water during dry spells. Glaciers can also be used to irrigate crops. In Switzerland's Rhone Valley, farmers have irrigated their crops fro hundreds of years by channeling meltwater from glaciers to their fields. Glaciers can also help to generate hydroelectric power.
