Many people drink soy milk and "Silk Soymilk" is the most popular. Sisters Elaine Tavani & Carol Jenson drink it.
This appears on the carton "A Plus for the planet"
"Did you know that your Silk purchase helps support organic farmers? In fact Silk is the world's largest user of US certified organic food grade soybeans. Plus, every delicious drop of Silk is powered by clean, renewable wind energy. That's two more reasons to sip with a smiile."

And on their website
"Silk Soymilk purchases wind power, an environmentally friendly electricity source, to offset 100 percent of the energy used in the production of its products. "
Our Thanks to Carol for pointing it out to Green Tavani
