"Howard Thomas Odum (1924, Chapel Hill, North Carolina–2002 Gainesville, Florida) (also known as Tom or just H.T.) was an American ecologist. He is known for his pioneering work on ecosystem ecology, and for his provocative proposals for additional laws of thermodynamics, informed by his work on general systems theory."

"Sponsored by Sun Microsystems, this free online community is designed to help participants calculate, track and reduce their organization's carbon footprint.  The GHG calculation tool currently focuses on emissions from electricity and natural gas use in buildings.  The new OpenEco.org Version 2 also provides a top-level organization dashboard where users can track a broad spectrum of emission sources to provide a comprehensive view of an organization's (or individual's) carbon footprint."
