Beautify your surroundings! Be kind to the environment and those around you by picking up trash when you see it lying around. It doesn't matter who left it there, just pick it up!
Picking up trash helps keep your neighborhoods, schools, parks, beaches, playgrounds, etc. clean and healthy. You will appreciate your surroundings more, and everyone else will, too.
Organize a group of people to go out and keep a specific area clean. Help with a beach clean up, or be a part of a relief team working to clean up after a natural disaster. Once a month commit to going to a local park or picnic area and picking up after others who may have left trash behind. You can also do this on the side of a road, or even on your neighborhood streets. And don't stop at just picking up garbage! Separate out the trash that can be recycled.
Always keep an extra bag to act as a trash bag where ever you go. You can keep it in your car, backpack or purse. Use this bag not only for your own trash, but also for other trash you might see lying around!
