Planting a tree does a whole lot of things for the environment -- from cleaning the air and water to reducing summer air temperatures and buffering noise.

The city has a mission to get more trees planted. And here are some opportunities to go get a free tree, or volunteer to help plant some.  

Here's a list of events this week, courtesy of TreeBaltimore and the Baltimore City Department of Recreation and Parks:
