old tire

In 2003 alone the U.S. generated more then 290 million tires. With an average lifespan of about five years unless recycled these tires will end up in the trash dump where they will take thousands of years to decompose. As the tires do decompose they will release harmful methane gas into the air, and worst of all create a toxic sludge that could seep into our waterways like your poop.
