Hydraulic fracturing (also hydrofracturing, hydrofracking, fracking, or fraccing) is a well-stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.

The global warming has been the center of attraction and number of conferences has been held in the last decade or so. This issue has become so prominent that on yearly basis discussions, conferences and debates are held. On the contrary, considerable change has not been witnessed.

Moreover, policies are determined in such a manner that best comes out into being and no shortage of resources takes place.
