Who says one person can't make a difference? Mindy Maslin took a job with the Pennsylvania Horticultural Society to teach kids about trees. She then turned that into organizing and training people to take care of the trees in their own neighborhood, and added a tree planting component as well. Over 26 years, 5200 people have graduated from her Tree Tenders program and 20,000 trees have been planted by citizens. And so what's the big deal about trees? They create a more pleasant environment to live in, they provide habitat for animals, they give shade, and studies have shown they even help reduce ADD in kids! One person can make a difference - and so can you. Have a listen on how she did it.
