Happy Earth Day

Hat tip to Dr. Mark Perry's Carpe Diem blog for those graphs. In his post on this, Dr. Perry comments,

Consider that since the first Earth Day in 1970, U.S. population has increased by 50.25%, miles driven has increased by 159% and real GDP has increased 203%; and yet air quality is better than ever.

It might have been Earth day but Buffett prefers Mars.

Would someone, anyone PLEASE make a comment on my site. It's very lonely talking to myself.
