Grassroots or Astroturf?

The Rainforest Action Network (RAN) appears to be a grassroots organization due to the fact the organization is made up of 36 members on staff, located in Califronia and Japan. Some of their volunteers for this grand organization includes: scientists, teachers, students and parents...generally anybody who is concerned environmentally! Their motto is to sustain that the world can be created and that aggressive action must be taken in order to secure the world for our future children. With their annual budget approximately more than $3 million. RAN has included several corporations participating including some popular businesses like Home Depot and Boise to change their practices. Overall, they fight for environmental issues by using grassroots technique.
