Dams and Mining

Date: 
Monday, October 22, 2007

Aluminum is a versatile material familiar to nearly everyone on the planet, and is used in airplanes and automobiles; in kitchen foils and pots and pans; for beverage cans and restaurant takeout trays; in window frames and electrical wiring; and for baseball bats and bicycles. Its many qualities have made it an ever–growing presence in consumer items worldwide.

However, aluminum’s apparent cheap economic cost belies the high environmental costs of its mining and refining: forests destroyed, water contaminated with aluminum wastes, fertile valleys and pristine ecosystems submerged under dams built to power smelters. The human costs of producing familiar aluminum items are also great, and include serious impacts on community and worker health. The conversion of bauxite, or aluminum ore to primary aluminum is also the world’s most energy-intensive industrial process, and aluminum producers use more electricity than any other industry. The aluminum industry is also a significant contributor to global warming.

About half of all electricity consumed by the aluminum industry comes from hydroelectricity, a percentage that industry experts predict will increase in coming years. Many dams have been constructed worldwide to power the aluminum industry. Among the best known and most destructive are Tucuruí, in the Brazilian Amazon, which flooded 2,860 km² of rainforests and displaced more than 24,000 people; the James Bay Complex in Canada, which flooded nearly 16,000 km² and has affected hunting grounds of the Cree and Inuit indigenous peoples; and Akosombo, in Ghana, which created the world’s largest man–made lake (8,482 km²) and displaced 84,000 people. Destructive hydroelectric projects currently being planned or developed in Iceland , Malaysia, Cameroon and Brazil will also fuel the expansion of aluminum production.
