Climate Change Climate change, otherwise known as global warming, has become more evident in recent years, with an increase in natural disasters, significantly warmer temperatures, and unreasonably long seasons. Global warming is one of the major concerns that scientists have investigated over the past century. Scientific evidence shows that global warming is caused by human behaviors. Due to the amount of man-made carbon dioxide and other greenhouse gases released into the air, the earth is becoming a highly poisonous place to live. Earth's climate has been constantly changing since the Industrial Revolution, when innovations began and factories were built that emitted massive air pollution. As technological advances continued in the years that followed, the amount of carbon dioxide in the air also increased. According to the UPI Space Daily News, “Global emissions of carbon dioxide (CO2) – the leading cause of global warming – increased 45 percent between 1990 and 2010, and reached an all-time high of 33 billion tons in 2010” (Writers 1). The period from 1900 to 2000 is the period in which humans caused the most air pollution by creating vehicles and other industrial machinery. In the contemporary period, human activities that contribute to climate change consist of hydraulic fracturing, rice cultivation, increased burning of fossil fuels, and increased deforestation. Hydraulic fracturing, which is the process of extracting natural gas, has been the subject of debate in recent years. It was first introduced in the late 1900s, as a cost-effective way to obtain clean fuel, and has also benefited the economy by providing jobs for many. However, recent studies have shown that hydraulic fracturing is causing... middle of paper... artificial resource costs, and humans are causing it. These destructions not only cause global warming, but also endanger the health of many as the climate often reflects the health of individuals. Gas released into the air from fracking and chemicals from burning forests can be breathed in and have health effects. Human act of terrorism, such as the September 11 terrorist attack on New York City, can also cause greenhouse gases to escape into the atmosphere along with other air pollutants. Even driving a car contributes to the amount of carbon dioxide emitted into the ecosystem. Individuals do not bother using alternatives because they tend to choose the most convenient lifestyle. Human activities such as fracking, rice cultivation, fossil fuel use, and deforestation all contribute to global warming.
