“Atmospheric carbon dioxide levels… have increased 40% since preindustrial times” due to fossil fuel burning (Baehr & Harvey). Today refineries use multiple methods to extract fossil fuels sufficiently and economical compared to the past. Fracking is one of the most commonly used way of removing gas, first they “[drill] down into the earth, then use a high-pressure water mixture...directed at the rock to release the gas inside” (“What is fracking?”). The term fracking refers to the type of fracture the rock creates due to the high powered water spout. Fracking has numerous negative effects, it cause health problems along with environmental issues. Fracking causes radon “a naturally occurring radioactive gas formed by the decay of uranium in rock…moves through the ground and into the air,” and affects people 's health (Apple). Fracking also causes more hurricanes due to the water heating from the greenhouse …show more content…
Emission gases have caused defective ocean acidification, which “serves as a sink for this gas and absorbs about a quarter of human carbon dioxide emissions, which then goes on to react with seawater to form carbonic acid” (“What Are Greenhouse Gases?”). Along with ocean acidification, ozone pollution, unhealthy plant growth, ozone depletion also occur as a result of emission. According to Dr. Smith human actions have not caused an increase because “the sun 's intensity, earth orbital cycle and volcanoes all produce small changes in temperature that affect” the earth. Greenhouse gases have always existed and have little to due with industrial use. The overabundance of methane is a result of the unnecessary industrial industry. Overall, the core Earth temperature has risen in temperature due to large populated cities and natural effects from the evolving
