Earth Day serves as a reminder that we all need to do our part to keep our planet clean.

You might be surprised to know that doing your part simply means not littering because the city and county don't regularly pick-up roadside trash.

Today Newscenter Sixteen caught up with one volunteer who likes to pick up litter for exercise.

Retiree Larry Alexander picks up roadside trash every so often. He says it’s a great to way to get out of the house and help out the environment. Otherwise homeowners are faced with the task.

“I do it mainly for exercise but mainly I've just always been one that I can't believe people wouldn't take the time to take their trash home and throw it out,” says Alexander.

If an area is covered with trash and becomes a problem the city or county can be called out to clean it up. The city of South Bend also has a street sweeper the regularly cleans the sides of streets. In other parts of Indiana the county jail may use inmates to pick-up trash but right now St. Joseph County doesn't have a program.
