Save the planet. Whenever I've read that bumper sticker I've had to laugh. Save the planet. What for? And from what? From ourselves? Life's simple: kill or be killed, don't get involved and always finish the job. A survivor's code, my code, and it all sounds great until the day you find yourself confronted by a choice. A choice to make a difference, to help someone, or to walk away and save yourself. I learned something that day: you can't always walk away.
