Is the Environment suffering?


The environment is indeed suffering. Increasing release of greenhouse gases such as carbon dioxide and nitrogen dioxide has led to an increase in the average global temperature over the years, from 1880 to present. The most worrying now is that the average temperature is expected to continue rising with the increasing amount of greenhouse gases released now.

The rise in temperature of the atmosphere has brought about serious consequences. Firstly, it has caused the vast ice caps at North and South Poles to melt which in turn caused the sea level to rise. Though the impact of rising sea level is not so visible, however in time to come, low lying areas will be submerged in water. In other words, lives would be lost and financial cost would be iccurred. The rapid melting of ice caps would also result in the extinction of life in Artic or Antartica, polar bears and penguins. This is because they would be confined to small standing grounds and extincted if the ice caps were to be completely melted. Next, rising temperatures would cause famine. This is due to the changes in the temperature of soil. Every crop would grow best in different soil temperature. Thus by increasing the temperature of soil due to rising atmospheric temperature, crops would not grow optimally causing insufficient food supply, famine. Lastly, the rise in temperature would affect the weather. As such, more natural disaster would be more frequently seen, such as hurricanes and tornadoes.

Release of carbon dioxide gas to the atmosphere comes mostly from exhaust pipes in vehicles' engines. Moreover the usage of cars has increased over the years due to increasing demand for luxury good as people now have greater purchasing power compared to the past. One should in fact take transport such as trains or buses instead of driving cars as this would significantly decrease amount of carbon dioxide being released should everyone be environment conscious.
