Earth Day in Toronto is the perfect occasion to go to the park and light up some joints while reveling in the magic that is the existence of trees attend some nice environment-friendly events. Because this crucial enviro-friendly holiday falls on a Monday this year, some of said events fall on the Sunday prior. Here are my top picks for green events this April 21 and 22.

Paper People's Clothing Swap and Shop
Fresh Collective is holding a swap of high-quality sartorial gems on Earth Day proper, from 6 p.m. to 8 p.m. They suggest bringing in items you'd lend to a friend (read: no cigarette burns/beer stains/sweaty festival residue). And this event is no free-for-all. It's an organized, decent person's round of recycling. Check out timing and rules here.

Earth Day in the Valley
Ever wanted to make some "environmentally friendly art" and/or dissect an owl pellet? This is the event for you. Does the thought of tiny mouse bones that were once part of a living creature make you want to weep bitter tears of pain and loss? Then I would forgo this one. That said, the day also includes a tour of a wildflower preserve and discussions on the impact of industrialization. I'm clearly having a nerdy day, since I think this actually sounds fun. This event will take place on Sunday at the Todmorden Mills Heritage Site between 12 p.m. and 4 p.m., and it's free.

Earth Day Screening: A Fierce Green Fire
Hot Docs Cinema is screening A Fierce Green Fire on April 22. The film offers an overview of "the environmental movement spanning fifty years, from conservation to climate change." Some serious voices are behind the narration: Robert Reford, Ashley Judd and Meryl Streep (who will be forever terrifying because of The Devil Wears Prada), to name a few. Tickets are $11 ($8 for members) and can be purchased here.

Earth Day at Scarborough Town Centre
We all know Toronto is fabulous, but equally un-debatable is the fact that we need all the help we can get when it comes to air quality. On April 22 from 10 a.m. to noon, you can head to Scarborough Town Centre for an old-school Earth Day community cleanup and tree planting sesh. Forty trees will be planted in a commemorative garden, and there are even free hats and t-shirts!!!!

Earth Day Family Art Event
While admittedly not for the child-unfriendly/sensitive-eared among us, this event sounds otherwise awesome. You can learn to turn old magazines into beads!!! There will also be a "fine-art collage making session." Held at the Art Works Art School at 238 Jane (just north of Bloor), the event takes place April 21 from 2 p.m. to 4 p.m. I just might get me some earplugs and hit this one up.
