Starbucks, is a worldwide known company, which uses thousands of paper cups a day. As they have been making efforts to use resuable materials in these cups, they have come up with an idea to sell reusable cups for $1 and give a discount on each cup of coffee for using it, thereafter. I really love this idea, because it is giving an reward for thinking more green and eco friendly. I went to the site for more info, and they have all kinds of plans for becoming a greener company. It was inspiring to see a big company trying to make a difference.
