As per our writing exercise in class, here are a few reasons why Wal-Mart should go green:
They are the largest chain of stores in the world and as such they have thousands of trucks and other large vehicles that consume massive amounts of petroleum fuels.
They have hundreds if not thousands of warehouse sized stores that consume insane amounts of electricity which comes mostly from coal fired power plants.
They sell a lot of products that are not sustainably produced and have a lot of waste associated with their use and eventual trashing.
Not to mention that many of their overseas plants and factories are pollution spewing monsters that have a tremendous drain on the environment.
