Trillions of cubic feet of oil and gas may be present beneath the Earth’s surface, drilling companies say. But it can only be done through a process called fracking.
Hydraulic fracking is essentially designed to recover gas from shale rock by drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Using water, sand and chemicals, these are injected into the rock at high pressure allowing the gas to flow out to the head of the well. This process can be done vertically or horizontally to the rock layer, to create new pathways for the gas to be released.

For starters, it does still promote the use of fossil fuels instead of forwarding the use of renewable sources of energy. The continued reliance to these activities mean that we carbon footprint. Apart from that, environmentalists claim that potentially carcinogenic chemicals used may escape and contaminate groundwater around the fracking site.

Using this process also entails huge quantities of water required to be present at the fracking site, entailing significant environmental cost. Moreover, fracking, being an event of vibrations, can cause small earth tremors and even trigger earthquakes.
Is this an accurate description from the environmentalists? Does fracking really harm our environment? Share your thoughts (comment box below).
