Walking Fido? Pick Up Some Trash While You Do It!

Every day I like to take my dog for a walk. Its good for him and it clears my head of all my worries of the day. A while ago I noticed that there was a lot of trash around my neighborhood and it really started to bother me. Whenever I see trash I always pick it up to throw away later but lately I've been collecting handfuls of trash. To make it easier on me I attached on of those doggie duty bag holders to the back of the leash so that whenever I see trash I can pull out a bag to put it in so I can throw it away later. I've started to notice a remarkable difference in my neighborhood; it looks a lot cleaner. It makes me feel so good when I know I'm doing something good for the environment. Now whenever I walk anywhere its an instinct to pick up trash I see on the ground! What small things do you guys to do help the environment?
