Matt studied Environmental Science and works in that area, and is a weather and resolved climate change 'believer'.  Hence, Matt is another 'Greenie' who hugs trees 'cause trees provide photosynthesis to extract 'C' from 'C02' to convert to '02', which we humans need to breath.  Matt was born in 1968 which in Chinese astrology is 'Year of Monkey'.  With David aka TreeHugger already stolen that 'handle', Matt nominated Green Monkey.

BankTeller did his own research on Green Monkey and noted:

"Green monkeys which are now found in Barbados originally came from Senegal and the Gambia in West Africa approximately 350 years ago. About 75 generations have occurred since these monkeys arrived in Barbados and, as a result of environmental differences and evolution, the Barbados monkeys today have different characteristics than those in West Africa."

Apart from a few remaining 'Creationists' who believe that 'terra firma' started with Adam, Eve, God and a 'forbidden apple' in the Garden of Eden 4,000 years before the birth of Jesus of Nazareth, most of us are 'Evolutionists' who accept as credible that humans have slowly evolved/developed/become more intelligent over the last 3m years, after abandoning 'swinging from the trees on all fours' to habitat the Savannah Plains in East Africa and lope around on two legs.  Perhaps Matt akaGreenMonkey has researched his 'family tree' all the way back to West Africa and his distant cousins now live in Barbados.
