Oil and Global Warming

• The biggest overall contributor to global warming is power generation that accounts for almost a quarter of the contribution to manmade global warming. The biggest single contributor is deforestation which accounts for a little under a fifth of the manmade contribution to global warming. The other major contributors are transportation in all forms - fuel for cars, planes, ships, trains etc, this is mainly carbon dioxide. The agriculture industry is another major contributor and the single biggest contributor of both methane and nitrous oxide gases.
• The majority of tar sands deposits are found under boreal wilderness. The depths at which these deposits lie requires everything on the surface to be scrapped away in order for extraction to be possible - destroying the wilderness forever. When current and future tar sands development are combined the area of destruction will be the size of England.
