I’m no psychic, but I’m ready to make two predictions for travel this summer: 1) Eco-tourism will be super-simplified; and 2) Travelers will toss out their chunky guidebooks in favor of the new eco-friendly travel resource called Summer of Green , unveiled earlier today by Google Maps .

With Saturday being Earth Day and all, I thought this might be a good time to talk about earth. Not the planet Earth; just plain ol' lower-case earth.

Have you been treating your dirt like dirt? So many of us never give the earth beneath our feet a second thought. Admittedly, it's not a terribly glamorous topic; in fact, soil gets little or no respect in the media, often being portrayed as something bad, or "dirty."

You still here? It's Saturday morning, it's Earth Day, and you're sitting at your computer? Draining the grid? Don't you know that the Internet begins with coal?

Sorry, a little Earth Day humor: "The Internet Begins with Coal" was the title of a debunked 1999 study, funded by the coal industry, that called for major U.S. investment in electric power – fueled by burning coal, of course – to feed the allegedly enormous future demand the Internet would place on the grid.

Our favorite enviro funny men Dave Poncé and Dan Wright, a.k.a. Rustle The Leaf, have, in collaboration with those squeaky clean folks at Citra-Solv, created a step by step guide to the upcoming Earth Day on April 22. With their inimitable straight talking and funny cartoons Rustle The Leaf always manage to convey the most serious of messages with a humorous twist. The Earth Day Book is a 12-page booklet filled with activities and information about Earth Day and other environmentally-related topics. The inside cover detaches to reveal a beautiful, full-color poster called ‘Rustle the Leaf's Earth Day Pledge.' There are 100 000 copies which they are giving away on a first come first served basis, so you better move fast since Dave Poncé tells us they are going like hot cakes - 10 000 were ordered on just one day last week! The Earth Day Book is completely free, you don't even have to pay for post or packaging. You can order your copy until March 20 at Rustle The Leaf or Citra-Solv.

Back in 1989, when the words "global warming" were only just beginning to enter the vernacular, Bill McKibben was way ahead of the curve. His book The End of Nature has since become a classic on the environment, but back then it was a revelation, laying out the science and implications of global warming and telling a great story to boot. Since then, McKibben has written seven more books, including Hope, Human and Wild, about local environmental success stories; Maybe One: A Case for Smaller Families, about population growth and the decision to have only one child; and "Long Distance," about a year spent training for long-distance cross-country ski racing. (He's also written books about genetic engineering and how to make Christmas more meaningful and less consumer-driven.)
