Written by The Worldwatch Institute

Vital Signs, 2011 contains, as has previous editions, some good news and some bad news.  Some of the good news: Solar photovoltaic capacity increased, by 20% in 2009, global wind power capacity grew by more than 31% overall, biofuels production increased by 9.6, farmers produced a near-record crop of grains at more than 2.25 billion tons--but the sea level continues to rise, human population is expected to reach7 billion by Halloween 2011 and 1 billion people go hungry each day.
