What is global warming? As defined by Encarta Dictionary it is an increase in the world’s temperatures, believed to be caused in part by greenhouse gases. Holli Riebeek on NASA’s Earth Observatory website describes it like this: “Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases.” She states, “surface temperatures have risen on average .6 - .9 degrees” in the past hundred years and that, “the rate of temperature increase has nearly doubled in the last 50 years.” She goes a step further by boldly declaring that the gases are the direct result of “people burning fossil fuels” (Riebeek). Researchers, scientists, nonprofessionals, and I agree …show more content…
Improved nutrition and “improvements in public health from the scientific revolution drastically reduced the death rates and increased live birth rates” (Marten). Since that time, the population has increased substantially. Below is a chart from Human Ecology that depicts the population growth over a 200-year span. With the increase in population came an increase in deforestation for shelter and home heating. The incomplete burning of fossil fuels produces and releases carbon monoxide into the Earth’s atmosphere. (Wang-lecture notes) It stands to reason that man has left an impact on his environment, and the main element of that impact comes in the form of air pollution. The components of air pollution are nitrogen, smog, particulates, acid rain, and carbon monoxide (Wang-lecture notes from class). “The main source of nitrogen dioxide resulting from human activities is the combustion of fossil fuels (coal, gas and oil), especially petrol used in cars” (Nitrogen Dioxide). Petroleum and coal also contain sulfur when burned it produces sulfur dioxide. Nitrogen dioxide when mixed with sulfur dioxide and water vapors form an acid, thus the term acid rain (Wang-lecture class notes). Acid rain destroys ecosystem required by slugs and snails by leaching calcium from the soil that is the source of calcium for egg layers. Without the
