The Economy on Global Warming



The Economy on Global Warming

Global warming had become a perilous issue since the beginning of its discovery. Global warming is the increase of temperature in the earth surface which had abruptly caused climate change all over the globe. From the late 1800’s we had increased from 0.7o to 1.4o F (0.4 to 0.8oC) and most scientists predict that the average temperature will rise from 2.5o to 10.4oF (1.4o to 5.8oC) in the year 2100. This means that the earth will endure intense heat and the percentage of survival depends on the rate of adaptation that the living beings and natural environment could perform.
Global warming started way back 18,000 years ago. The climate that was experienced back then was not as what is right now. Global warming is primarily caused by a process called the “Greenhouse Effect”. It is a process in which certain gases such as carbon dioxide (CO2), methane (CH4), ozone and water vapour traps the heat radiated from the sunlight and the heat that was supposed to be released in the outer space and reflects it back in the earth’s surface. These gases are natural gases produced by the earth’s atmosphere and the chemical reactions it had driven from the earth’s surface. These gases are in a routine in the earth’s natural processes but human activities mostly derived by industrialization and technology advancement had intensified the production of such gases and made the earth’s atmosphere more intensely warm. Carbon dioxide for example is abundantly produced by burning fossil fuels (oil, gas, petrol, etc.) which are mainly used in factories, the use of windshield washer releases ozone and some particles of methane to the atmosphere, and there are several other industrial activities which release these gases.
The earth’s natural processes could accommodate the production of these greenhouse gases such as Carbon dioxide (CO2) which is used as one of raw materials in “photosynthesis”, the food producing process of plants. In this process Carbon dioxide (CO2) is broken down into Carbon for later food process and Oxygen (O2) is released to the environment for animal respiration. However, the rapid growth of industrialization produced severely abundant amount of this gases through factory smokes. Buildings also required woods, therefore making a huge pile of logging activities that had skinned the forest, exterminating thousands of trees and plants. The society becomes advanced yet disturbing the natural processes of the earth. With the rapid advancement of the earth’s industrial society, Global warming has a greater percentage of becoming more intense.
The expansion of industrialized societies leads to greater economic growth. The machines and factories that we have will soon develop into more innovated ones. However, these innovations will not assure the security on the economic growth. To become more advanced is to defy nature. To extend beyond what is naturally in earth, thus breaking the rule of the natural processes. The terrifying effect that could be brought by Global warming could be hastened, which means a total 90 degrees roll over of the economic condition. The Philippines for example is not a money based industry, we gain living mostly through agriculture. Sunlight might help through the process of photosynthesis but when the heat goes extremely unmanageable the crops could no longer tolerate the heat and will eventually die. It had been experienced by the late 90’s through an “EL NINO” and the worst could not be imagined. Plants and animals will have to adapt sudden climate change which could force them to jump from one habitat to another. Aquatic environment will be affected due to intense heat in the sea surface and the reefs will soon bleach and unless cooling effect reaches them, they will die. Sea animals will then move from one place to another and when the time comes that they could no longer find food, they will die as well. This would mean a great impact in the economic society. Economy does not purely revolve on money and industry, it also needs raw materials and these raw materials and food process for human requires help from the living environment. This makes other animals and plants potent to survival.
Economy and natural earth processes are suppose to be in equilibrium. This makes man work for alternative and non-synthetic processes. One great example is the use of Bio-fuel which is driven from long dead biological material. Bio-fuel has the added advantage of biosequestration of atmospheric CO2 and so assisting to remediate greenhouse gas and climate change problems. The need for alternative biological processes is a must for the human society. It will extend the percentage of survival of the people and the earth.
Global warming is inevitable, as it is said; it is a natural earth process. As a matter of fact Global warming has saved us temporarily from 100,000 years of Ice age. Where the earth is covered with thick Ice sheets and obliterated many forests all over the world. The processes that mankind will be taking is a great consideration that every continent must have. Or someday the worst could happen, as known to the systems of the earth there are sub-systems called the “spheres”, four of them are common: the Lithosphere, Hydrosphere, Biosphere and the Atmosphere. But there is one sphere in the earth that is composed solely by ice sheets, the Cryosphere. If Global warming gets too intense which is predicted, this sphere will be greatly affected and could totally melt. Since the earth is composed of only one forth of its land surface, we could not imagine finding the earth surface after the melting.
