Plant a tree or a small plant in your garden or a pot.

“The very first tree I ever planted was a gingko. My Mom and I, with not much discussion or ceremony, planted 10 seeds in small plastic pots. [...] I watched her dig up a patch of grass in the side yard. In the process of getting the gingko out of the pot, I knocked all the soil off of the roots. I was horrified-I thought I had killed it. She just scooped up that bareroot tree, and planted it in one fell swoop-the entire planting took but seconds. I would be in charge of the water to that tree for years to come. [...] There was a lot of satisfaction to watching that tree grow-and grow it did.”
