Nevada – Leaving No Trace is arguably Burning Man’s most important principle. “If we don’t uphold that one, no more Black Rock City. But Leaving No Trace is not just about the playa; it’s our ethic about the whole planet. Burners are environmentalists. It’s just our nature.”
Apparently 5,000 visitors weren’t aware being environmentalists, leaving an enormous amount of bikes behind at the festival terrain.
