The major problem of hydraulic fracturing is its contribution to climate change. The technique use fracturing fluids and toxic drilling fluids, which are injected deep underground. According to McGlynn, “opponents say the underground tunneling increase the likelihood of contaminating aquifers” 1061. The process is attributed to injecting and withdrawing the water into the underground, which may result in contaminating surface waters and underground aquifers. Moreover, the process may result in noise and diesel pollution because the process operates 24/7. Hydraulic fracturing emits air, which may include volatile organic compounds that are disastrous to the employees and the humans/animals within the vicinity. In addition, the stress conditions involved in the process especially in the communities in which the drilling is done contributes to additional challenges. These numerous process affects the fauna and flora of the identified localities. Hence, hydraulic fracturing contributes to climate change due to the processes involved.
