Tar sands extraction — mining oil from a mixture of sand or clay, water and very heavy crude oil — uses a huge amount of energy and water. Environmentalists say it results in more than three times as many emissions of carbon dioxide compared to conventional oil production.Na, fühlt ihr, wie es mit der Umwelt schon bergauf geht?
