Scientists do not know enough about fracking to draw a conclusion about the risks of this technology.
People who live close to fracking sites and some scientists argue that fracking may be harmful to humans and
the environment. Drilling companies and some scientists argue that fracking is an important source of clean
energy and has not been scientifcally shown to be harmful.
