GLobal Warming - Research Paper Example That global warming has happened in the recent past is evident from the rise in the mean temperature of the earth’s atmosphere. Many ecosystems will be unable to adapt suitably to such rapid changes in climate and this will lead to extinction of some animal species. In addition to the impact on ecosystems, human agriculture, health and water resources are all being affected by global warming sparking wide spread apprehension across the globe. Scientists agree that human activities have led to release of green house gases that in turn are responsible for global warming during the last century. This has been especially marked during the last 50 years. As humans began to use petroleum and burn coal and oil to heat their cities and run their machines, levels of carbon dioxide have risen by almost 30%. The concentration of nitrous oxide and methane that are by products of farming, coming from rice fields and cattle have also risen by 10 – 15 %.

The novel begins and ends the story through the mechanism of a double narration: one a young student collecting songs and folk stories from the peasants in the countryside and the other, old Fugui and his ox telling their story to the student.
