Just how hard can it be to go green once and for all? Well, think of the next scenario: you are the owner of an emerging company that sells LED light bulbs. So far, so good. But you desperately need to make your company seen and heard on the market. So you eventually feel the need to spread flyers all around the city. But do you feel that would be a cruel thing to do. After all, a great deal of trees needs to be killed so that you can have your precious colored flyers flown around the city so everyone can see.
