From Karachi, Pakistan to Koh Samui, Thailand to Chelewah, Washington people are celebrating the earth this weekend. Yep, Earth Day is April 22. You can plant trees, clean up a beach, go to a lecture, canoe, pet animals, hike, dance, sing, participate in a 5-K run and eat Earth Day fare at an Earth Day fair somewhere on the planet. The calendar page of the website Envirolink: The Online Environment Community lists scads of possibilities.

Each link goes to a link that links to each event's website for more information. This is a place you can spend a lot of time just to see what people who are environmentally conscience are up to. Here's one event that caught my attention. John Muir's Birthday Hike is taking place near Madison, Wisconsin. Muir was the founder of the Sierra Club and his boyhood home is part of the John Muir Memorial County Park. This event includes talks about Muir and his writing. Plus, there is a hike and a tour of the house he grew up in.

To find an Earth Day event near you, check out the Earth Day website. It looks like you can type in where you live and events near you will pop up. If you're wondering what started Earth Day, here is an overview.

Also, stay tuned for Gadling's April 22 posts when Gadling writers' pay homage to Earth Day with their special brand of posts and whatnot.
