Once Upon a Time... Life
Today, Peter and his friends are meeting for an endurance run in the park. Athletes, that run very much, need to breathe a lot as well, so that enough oxygen is provided for the body. However, when we breathe, it's not only oxygen that enters the body, but also dust particles, exhaust gas, and some other more or less toxic substances.
