Earth provides an amazing variety of plants that produce oxygen, prevent soil erosion, filter air pollution, contribute to soil fertility, and recycle water. They don't deserve to be covered with trash. Picking up litter shows that you care and are aware of our reliance on Earth's many provisions. Some sources say that "plogging" (picking up trash while jogging) is currently the hottest fitness trend. Whether you are adopting a highway mile, a nature trail, a bike path, a park, or just going for a walk, picking up trash is a great way to keep America beautiful.
