In remarks made at a Washington thinktank, Oliver said Hansen should be "ashamed" of his opposition to the Keystone XL pipeline, and for warning that exploitation of the carbon-heavy tar sands would drive climate change past a point of no return.
They laid a mock pipeline in Grosvenor Square from the Canadian High Commission to the US embassy, as a sign of their "outrage at the continued exploitation of high-carbon tar sands", lobby group Campaign Against Climate Change said.
Opponents of the pipeline claim that by facilitating the exploitation of particularly carbon-dense Canadian tar sands, it will substantially increase greenhouse gas emissions into the atmosphere.
The possibility of converting CO2 into useful chemicals could be a good strategy to both decreasing the CO2 concentration and for achieving an efficient exploitation of this cheap carbon source.
The efforts to meet such challenges via isolation of metal-resistant bacterial/fungal strains and exploitation of organic wastes as carbon substrates have began.
The exploitation of the Biolog's carbon sources as electron donors for molybdate reduction was not possible since we discovered that the purplish color of the reduced formazan was too intense and masked the appearance of molybdenum blue.
Second-generation biorefineries based on the exploitation of lignocellulose as the main carbon source, have the potential to produce a variety of products, including bio-fuels, value-added chemicals, materials, heat and electricity [ 1– 3].
