Keith, I'm with you, but you have to be more optimistic. As Cecil says, Mother Earth can take pretty good care of herself. She has checks and balances, and a counter punch for every punch thrown at her.
But you're right about the population. Everyone complains and worries about the symptoms, but nobody complains about the root cause. You're correct about land being a great investment, too. It's a safer bet and better investment than 30 year treasuries.
