DEVELOPMENT VS. ENVIRONMENT? Must we forget development if we want to preserve the environment? Can’t we upgrade efficiency of the tools for developoment? ALTERNATIVE FOSSIL FUEL SOURCES: A STRONG CONTROVERSY Exploitation of alternative fossil fuels such as shale gas, tar sands, fracking, etc. face an unsolvable controversy: desperately needed for development, and strongly promoted by oil companies as part of their monumental business, they are strongly opposed by environmentalists and neighbourhood  populations.  There is an urgent need to promote efficiency either through investment or through regulation.
