7 ways oil and gas drilling is bad for the environment

The health risks from oil and gas extraction are not limited to air pollution. The drilling method of "fracking" is known for contaminating drinking water sources with chemicals that lead to cancer, birth defects and liver damage. The controversial method injects a mixture of water and chemicals into rock formations to release oil and gas.
