If Earth Was A Dog, Humans Would Be Fleas

Like a dog or any other living creature, Earth is a breathing living planet.  Just like with any form of life, bacteria or fleas can come along for the ride and cause harm.  We cause rashes to our dog Earth, we cause him to scratch his fur away, but that's ok we have are home, and really we are not causing any harm.  As we pollute the waters it is as if we have polluted the blood flow to our dog, Earth.  Will we wise up, or does Earth need a flea collar? timothymahar.org
