This morning on NPR I caught a couple stories about some changes at Walmart. Now, many people, including some authors on this blog, have been critical of the practices of Walmart. They have long been criticized at anti-worker and anti-environment. Well, some leaders at Walmart are working to turn over a greener leaf. They are pushing for healthier foods and considering the environmental impact of their supply-chain. They are considering some of these changes because it is good for the bottom line. As someone who has been critical of Walmart, I have to say that this is a move in a better direction. I think they have some ground to cover to it is nice to see them doing something. I think that consumer pressure is a powerful force.
