Is Soy milk sustainable?
A lot of the large companies producing soy milk use organic or non-GMO soybeans sourced from Canada and the U.S., a 2006 report from Green Peace exposed the link between soy's rising demand for land and the destruction of parts of the Amazon Rainforest. And, while nitrogen fixation reduces the use of nitrogen fertilizers, soy production still requires the use of phosphorous fertilizers. Phosphorous fertilizers are connected to chemical runoff that creates dead zones, or areas of water where marine life cannot survive due to a lack of oxygen (via Civil Eats). So, next time you hit the grocery store to re-up on your soy-milk stock, you should think twice and opt for brands like Silk that use certified organic beans.
