This week's cartoon describes wastewater bioremediation, the process of using micro-organisms, plants, fungi and their powerful enzymes to remove toxic substances from our wastewater. Read through the Worldchanging archives to learn how bioremediation can work on rainwater, contaminated city parks, and even industrial wastewater. Unlike traditional treatment plants, the right critters can naturally clean water and soil polluted with anything from uranium to ddt without using dangerous chemicals or non-renewable energy.
Editor's note: This post is part of a series featuring Worldchanging ally Andy Lubershane's original graphics. While many of the issues covered in the comics have been discussed on Worldchanging in the past, we hope that you'll be able to use this new medium in a different way … whether it's in your classroom, on your office wall, or to help explain ideas to friends and family.
Andy Lubershane researches, writes and cartoons about sustainability from his home in Boston. Check out more of his illustrations here
