Boston isn't the best place in the country to celebrate Earth Day, the pedagogical holiday started in 1970 by Senator Gaylord Nelson to teach people about environmental issues. Our own spring holiday involves more redcoats and Red Sox than anything that's green.

But, if Earth Day is your bag, there are a few things around town for you to do today.

Boston Children's Museum, which promotes itself as Boston's "first green museum," hosts a special Earth Day presentation for kids. The event promises to teach kids about the history of environmentalism and the wonderful organisms known as trees. 11:00am-3:00pm. Free.

Suffolk University hosts Earth Day Extravaganza 2008, featuring lectures, a cell phone recycling, and a Red Sox tickets raffle. 12:00pm-2:00pm. Free. More information.

Tufts University's Department of Urban and Environmental Policy and Planning presents Van Jones, a civil rights activist, who will give a talk on environmental justice. 6:00pm. Free. More information.

Saturday, celebrate a belated Earth Day with the 9th Annual Earth Day Charles River Cleanup. Sites are seeking volunteers up and down the Charles and on its tributaries. For those who love dirty water. More information.

Also Saturday, join DotBike for an Earth Day Bike Ride. The group hosts a relaxing tour of Dorchester's many parks. Starts at 12:30pm at the Franklin Park Zoo. More information.
