"Farm Sanctuary is a national, non-profit animal protection organization. Each year we rescue, rehabilitate and provide lifelong care for hundreds of animals rescued from factory farms, stockyards and slaughterhouses. In addition to operating the shelters, we work to gain legal protection for animals used in food production and to raise public awareness about factory farm cruelty and cruelty-free alternatives. The Walk for Farm Animals helps fund Farm Sanctuary's rescue and protection campaigns."

You are now able to sponsor people online. Below is the link of one walker.
