Pollution is a serious concern in the modern industrialized world. However, industry is not its only source. According to Trailblazer Rural Development Institute Biologist Olivia Ward, it can be something as simple as a plastic wrapper thrown on the side of the road.
"We all live in a watershed; an area of land that drains to a single body of water such as a stream, lake, wetland or underground aquifer," Ward said. "When it rains, runoff drains into the water potentially carrying harmful pollutants from the land."
