Want to dig in the dirt for a good cause? 

Baltimore Green Works, the non-profit, volunteer-driven group that works for environmental education, is sponsoring Make a Difference Day this Saturday from 9 a.m.-1 p.m. in Fort Armistead Park.

Volunteers for the event will help with shoreline cleanup, invasive species removal, tree work and other things. That means lots of time in the dirt, on the water and in the woods.

It's sponsored by Lorenz, Inc. and Baltimore City Recreation and Parks. If you'd like to volunteer, contact Baltimore Green Works at bgw@baltimoregreenworks.com. 

There be other volunteer and learning opportunities. The group offers free and low-cost programming year round. That includes a Sustainable Speakers Series, Community GROWSHOPS and an annual Eco Ball. Check out the events page of the Web site for more information.
