Fracking, or hydraulic fracturing, is a process used to extract natural gas and oil from shale rock. It involves drilling into the ground and injecting a mixture of water, sand, and chemicals into the rock to create fractures. This allows the oil or gas to flow out of the rock and be collected.

What we know about fracking:

* Fracking can produce large amounts of natural gas and oil. The United States is now the world's largest producer of natural gas, thanks in part to fracking.

* Fracking can create jobs and boost the economy. The natural gas and oil industry supports millions of jobs in the United States.

* Fracking can reduce our dependence on foreign oil. By producing more natural gas and oil in the United States, we can reduce our reliance on imports from other countries.

* Fracking can be harmful to the environment. Fracking can pollute water supplies, release methane gas into the atmosphere, and cause earthquakes.

What we don't know about fracking:

* The long-term effects of fracking are unknown. We don't know for sure what the long-term consequences of fracking will be, including the environmental and health impacts.

* The risks of fracking vary depending on the location. The risks of fracking depend on the geological conditions of the area where it is being done. Some areas are more likely to experience problems than others.

Overall, fracking is a complex issue with both benefits and risks. It is important to weigh these factors carefully before deciding whether or not to support fracking.
