What is the science behind fracking?
Fracking is a technique used to extract oil or gas from underground shale formations. A mixture of water, sand and chemicals is injected at high pressure into the rock, causing it to fracture (crack).
Did you know facts about fracking?
Since fracking was introduced in 1949, over 2 million frack treatments have been pumped without a single documented case of treatments polluting a water aquifer. 3. 90 percent of all gas wells drilled in the United States since 1949 have been fracked. 4.
What are 3 bad things about fracking?
Air pollution and water contamination due to the toxic chemicals used in hydraulic fracturing are the greatest concerns within fracking sites, while the need for wastewater disposal and shrinking water supplies are also pressing issues directly related to the procedure.
Is fracking good or bad for the environment?
Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.
How harmful is fracking?
Fracking sites release a toxic stew of air pollution that includes chemicals that can cause severe headaches, asthma symptoms, childhood leukemia, cardiac problems, and birth defects. In addition, many of the 1,000-plus chemicals used in fracking are harmful to human health—some are known to cause cancer.

Can fracking cause earthquakes?
Fracking intentionally causes small earthquakes (magnitudes smaller than 1) to enhance permeability, but it has also been linked to larger earthquakes. The largest earthquake known to be induced by hydraulic fracturing in the United States was a M4 earthquake in Texas.
What are cons about fracking?
Con 1. The US needs to immediately transition away from all fossil fuels, including natural gas.
How does fracking cause earthquakes?
How does the injection of fluid at depth cause earthquakes? The fluid that is injected at depth is sometimes hydraulically connected to faults. When this happens, fluid pressures increase within the fault, counteracting the frictional forces on faults. This makes earthquakes more likely to occur on them.
How does fracking affect animals?
Withdrawing water from streams and rivers for fracking can threaten fisheries. Birds and other wildlife have been poisoned by chemical-laced water in wastewater ponds and tanks used to dispose of fracking fluids. Effects on wildlife include degradation of habitat and interference with migration and reproduction.
What is so bad about fracking?
In addition to air and water pollution, fracking also increases the potential for oil spills , which can harm the soil and surrounding vegetation. Fracking may cause earthquakes due to the high pressure used to extract oil and gas from rock and the storage of excess wastewater on site. Nov 19 2019
What is fracking and why is it controversial?
Fracking is controversial due to the potentially cancer-causing chemicals used to extract oil and gas, which could then contaminate local water supplies. Some also argue, fracking, which requires a…
How dangerous is fracking?
Fracking causes noise pollution that could be harmful to your health. The consequences of fracking can include higher cancer risk for workers, groundwater contamination, and methane leaks, as well as the sudden rash of earthquakes in places where they were previously rare.
What are the true effects of fracking?
Fracking Is Dangerous To Your Health — Here’s Why A variety of health problems are associated with fracking Respiratory problems: Cough, shortness of breath and wheezing are the most common complaints of residents living near fracked wells. Problems during pregnancy: Fracking chemicals are harmful to pregnant women and their developing babies.
