I think it's a good start. How about cleaning up parks in the area of just picking up trash in general? I know that may not seem like much but it would be appreciated by those of us that choose not to litter. Or helping homeless people in the area. Maybe you could make sandwiches for them or something similar. Just make sure you're with adults and all. Check with your local shelter and see if they need volunteers. I'm sure they'd really appreciate the help.
