The other week I gave the college students in my sustainability class a homework project. They had to carry their garbage, in a plastic or paper, bag with them for 48 consecutive hours. If they bought a plastic water bottle or can of soda they had to take that empty or half-full container and put it in their bag when they were done with it. If they went to a fast-food restaurant they had to take all of the wrappers and containers and put them in the bag too. If they cooked dinner and had zucchini scrapes and chicken fat that had to go into the bag too. At first they were shocked when I gave them the assignment. After a few minutes it started to sink in and they, as individuals, were going to see how much trash they created. Since I could not monitor each student they were on an honor system and had to report, with color photos, how they had done.

Most of my students thanked me for giving them this assignment. They had not realized how much plastic they used or how much garbage they were responsible for. Some even stopped using throw away plates and utensils and started using washable ones to cut down on the amount of trash they created. And many realized how much money they were wasting on buying water in plastic bottles instead of drinking from a re-usable container. A couple of students remembered that too much trash goes into the oceans and kills dolphins, turtles, and seals. And for every pound of trash we put into a landfill we put 40 pounds of carbon pollution into the atmosphere. So now I challenge you. How little trash can your produce? Why not try the homework assignment for 48 hours?
