For all of its environmental challenges, Baltimore has some pretty breathtaking natural spaces, and plenty of enthusiastic environmentalists to help take care of the them. Today is your day to get out and join them with some cleaning and greening, or even just hanging out.

Here’s a sampling of events happening today. All are open to all and free, unless otherwise noted.

Dovecote Café: A produce market with fresh goods from Baltimore-based Whitelock Farms and Strength To Love 2 Farms, plus locally made honey and a live petting zoo from McClain Farms and Apiary. Bonuses: face-painting, giveaways and seminars for home gardeners and “houseplant enthusiasts.” Look for it in the green space next to the café. 10 a.m.-5 p.m.

Family yoga with Lift Yoga + Strength: A family class for parents with kids ranging from kindergarteners to fourth-graders, using poses centered around Mother Earth and worldly creatures. “Fly like a bird, be a tree in the forest, or cuddle with your little bear.” $10 per child for Lift Yoga + Strength members, $25 for non-members plus one child ($10 more per additional guest). 3-3:45 p.m.
