Global Warming

Definition~
What is global warming? it is the observed and projected increase in the average temperatures of the Earth's atmosphere and oceans. It is a phenomenon, which has been on the rise but in the last century, the increase has been rather alarming. The average temperature of the atmosphere has risen by 0.74-0.18 deg. celsius during the last century. Studies have shown that this increase was due to the increase in greenhouse gas concentrations.

Problem~

One of the main problems in the world is the negative effects of shifting cultivation. In the process of shifting cultivation, the burning of trees is required. This causes an increase in temperature and greenhouse gases(produced during the burning) as well as forest fires which can lead to haze. The haze produced in turn travels to other countries like Singapore and can cause health problems. The main country which shifting cultivation is implemented is Indonesia.

Solution~

Malaysia used to have shifting cultivation. However, it was banned after the government realised its bad effects. This ban caused many farmers to lose their jobs as shifting cultivation was their 'life'. However, the Malaysian government was able to make up for this through alternative employment(solution). They also aimed to preserve their country's virgin forests and beautiful mountains. The farmers took up the roles of tourist guides as they knew the area well. Thus, all was well. However, this solution did not work in terms of implementation for Indonesia. Why is this so? Well, the natives in Indonesia were used to shifting cultivation and so they were unable to give up their jobs. The government thus have to sent down officials whom are passionate about saving the ecosystem to convince the natives about the above solution.
