Friday, April 22 is the day to show your appreciation for Mother Nature by planting trees, cleaning up trash or... partying.

Yeah, we have three ways to really celebrate Earth Day 2011.

University of Utah Earth Fest

Browse booths from local food purveyors and sustainability-oriented organizations on the Union Plaza from 10 a.m. to 2:30 p.m.

ASUU Director of Sustainability Norah Olley and SLC Mayor Ralph Becker will lead a bike parade around campus from 1 p.m. to 2 p.m.—be one of the first 100 to sign up for the ride and get a free bike lock. Oh, and it's also Bike to the U day for students and staff if, you know, you live close enough or have a TRAX stop nearby.

Alta's Earth Day Fair

Tons of free activities—adult green crafts and kids art, a recycled hat judging contest, job fair, vendors with plenty of free goods.

Also, take advantage of Alf's Restaurant's Earth Day sale when you buy a Cliff bar, Luna bar or Candy bar and get another one free. The Alta Ski Shop will donate five percent of its sales to Alta's local non-profits, and Alta Sports is donating free snowshoe rentals of the Snowshoe Tours.

My favorite, Watson Shelter will feature 100 percent grass-fed Utah beef in their BBQ beef sandwiches for $10.

A lot more is going on, too. Click here to see all of it.
