Great post! It's definitely a very important thing to bring awareness to.
I'm certainly not a supporter of Starbucks or McDonald's by any means, but I am proud of them for taking initiative in the matter, considering the amount of volume they produce.

Thanks for your article! I just stumbled upon you and am definitely going to keep up with your writing !
