The Home Depot is the largest US buyer of timber products from the Matte and Angelini Groups, two Chilean companies that are part of a consortium planning to build 5 dams on two pristine rivers in Patagonia, southern Chile. The dams and their associated transmission lines would ruin rivers, flood rare endangered forests and destroy livelihoods. The 1,500-mile transmission lines would slice through rare Patagonian forests, creating the world's longest clearcut.

We're calling on The Home Depot to stop buying wood products from the Matte and Angelini Groups, and to use their influence to protect forests and rivers in Patagonia from mega-dams.

In the past year, even after receiving thousands of letters and postcards from concerned customers, The Home Depot has continued to support the companies proposing the destruction of Patagonia by purchasing millions of dollars worth of timber from them.

Tell The Home Depot you won't shop with them until they use their buying power to keep Patagonia wild.
