Fracking, technically to as “hydraulic fracturing,” is a technique for extracting fossil from rock that is buried deep in the earth. First, a large well is drilled near a source of gas or oil. Then a of water, sand, and chemicals is pumped into the well. This creates breaks in the rock where the fuel is . The enclosed fuel is released, recovered, , and sold. Fracking is primarily used to recover natural gas.

While the has been around since the 1940s, governments used to think fracking was too expensive. Building roads, digging , transporting materials, and disposing of chemicals are all procedures. Fracking has become a booming industry in the US in recent years because the fossil fuels that are easy to have been used up.

Fracking is controversial because of the environmental hazards. Firstly, uses a lot of water! One well requires up to five million of water. In addition, chemicals used in fracking pose a to air and groundwater. Nobody knows for sure what the effects of these chemicals will be to humans. Traffic from tanker trucks also reduces air quality, and this is one of the primary of environmentalists.

Many environmentalists think fracking ought to be banned . Fractivists want governments to focus on developing long-term energy solutions. Clean, energy solutions include wind, water, and energy. But not everyone is opposed to the technique. Thanks to fracking, Americans are getting used to cheaper energy . Some studies suggest that there is enough natural gas to power America for the next 100 years.
