Al Gore's movie came out on dvd this week. An Inconvenient Truth is little more than a powerpoint presentation really, one that he has given for years, but it is a powerful commentary on global warming and a call to decisive action. It is yet one more example of how much the environment is taking centre stage as a seminal issue of ethical and social import for more and more people. Just in time for Christmas comes, World Changing, a book from the website of the same name, which offers countless ideas and plans for being more environmentally conscious. The book has 600 pages of stuff that is both creative and helpful. It was designed by Stefan Sagmeister, master graphic designer and all around provocateur. Sagmeister has done some seminal work, including a cover for Lou Reed's album, Set The Twilight Reeling, that changed the face of graphics.You can check out his site here.
