“What have they done to the earth?
What have they done to our fair sister?
Ravaged and plundered and ripped her and bit her
Stuck her with knives in the side of the dawn
And tied her with fences and dragged her down” by The Doors from When the Music’s Over
Earth is the third planet from the sun and in reality it is the only place in our solar system that we can easily call home. Presently, this planet supports a human population of just about 7 billion people….That’s a lot of people……..Still, it remains to be seen if our quality of life can be sustained with this many people on board.
