Earth Day is 43 years' old today, a milestone marked by one of Google's annual doodles dedicated to the event. The day of environmental awareness has been marked by a Google doodle for as long as I can remember, from melting polar ice in 2007 (a prophetic nod to the record Arctic melt that year), rocks in 2008, a waterfall and marine life in 2009 to parrots in 2010, pandas in 2011 and animated flowers in 2012.
