The quiz everyone (I know) will fail

Not as much fun as a cosmo quiz perhaps (unless you're Sheryl Crow or
Al Gore, then it's nirvana), but it will make you feel the same way
after you take it (namely guilty: for lying on something nobody knows
about but you and scoring badly anyway). If anyone gets only one
earth, let me know. You won't win a prize, but you may be able to
write an eco-stunt book/blog.
