TIME.com's First Annual Blog Index

In a green world, it's clear that the Internet has a huge advantage over the tree murdering print media in championing sustainability with a straight face. TreeHugger is the most complete of the hundreds of grassroots green blogs; think of it as the Wal-Mart of sustainability, if you can imagine Wal Mart being sustainable. It's a one-stop shop for green news, solutions, and product information, and it ranks among the top 20 blogs in traffic worldwide. Part of what makes it a good read is that Treehugger isn't trying to change the world overnight; more like one post at a time. There are scores of tips on how to reduce your environmental footprint while not radically changing your lifestyle—things like getting out of the bottled water habit, using a pressure cooker to reduce energy consumption, and buying and cooking food in bulk. One word of warning: steel yourself for plenty of guest appearances on the blog from eco-stars like Bono. Try to think of it as a form of recycling.

Sample Treehugger Post: Sexy play can be green and efficient as well. Showering together can save water. If things get steamier, we suggest taking it to the bedroom and not leaving the shower running.
