Here's today's challenge:
Plant a tree. One tree will absorb about a ton of carbon dioxide over the course of its lifetime. Trees also provide shade that could reduce your air conditioning bill significantly. Mass ReLeaf can provide matching funds and expertise for public tree-planting projects in Massachusetts. Find out if there's a similar program in your state. If not, consider starting one.
Until tomorrow ...
