With the rapid development of the global economy, the world 's demand for oil continues to increase. When conventional oil resources cannot meet the rapid growth of oil demand, people turn their attention to unconventional oil resources, which is an important source of oil sands. By the sand, asphalt, mineral, clay and water in five parts of the oil sands is a kind of unconventional oil resources. It is distributed widely, and is rich in resources. At present, the world oil sand technology is known to be about 1035.1 cubic meters, accounting for 32%% of the world total recoverable amount of 68%% .The Canadian Alberta oil sands, the world known recoverable reserves of 81%%. Canada 's oil sands reserves are among the world 's second largest

In addition, the United States and European countries have been heavily dependent on the supply of oil and natural gas in the Middle East, to find a new source of energy supply in Canada, is undoubtedly a political risk safety factor is high. At present, oil sands mining industry has Canada Alberta brought a large number of jobs and wealthy. Behind the oil sands "gold rush", it carries enormous environmental, social, and threatening human health. Two kinds of technical solutions for the exploitation of oil sands are now being attacked by environmental protection organizations. The first scheme (Strip-mining) is suitable for the use of a giant open excavation technology to remove a large number of surface vegetation, including grassland and woodland, and then into mechanical mining when the oil sands are close to the surface. The damage to the environment is irreversible. Second kinds of schemes (Deep-mining) are suitable for the deep underground with oil sands. The high temperature water vapor flow with high temperature water vapor flow over 300 degrees Celsius is used to separate the sediment and oil. This will greatly damage the groundwater and surface water resources, has caused water pollution and water level …show more content…
The question now is whether people will be able to minimize the impact on the environment at the same time. The impact of environmental problems on the development of oil sands can be decomposed into several aspects: the impact of greenhouse gas emissions, the impact of air and water quality, water consumption, energy consumption, the impact on the wildlife, the impact on the terrain and the impact on people. Environmental activists are divided into two camps, one with the natural resources conservation Council (NRDC) and the green peace organization, hoping to stop all the oil sands development. They believe that although the province of Alberta, Canada is the largest oil reserves in the world, was the world 's largest industrial projects, but the original ecological environment has been replaced by opencast mines, oil refineries and pipelines. The development of oil sands is a challenge to climate change, it will only make the situation
