Global warming

A. Problem and Solution

Global warming is a worldwide concern and the continuous thinning of the ozone layer caused by it reaches now to its alarming level.  Do we still have a solution for this problem?

B. Introduction

“The world is becoming warmer and this is an unusual occurrence because it dehydrates the earth. This is alarming considering that it will harm and endanger all the living things: men, plants and animals” (“Global Warming”, n.d).  The primary reason why there is the occurrence of this phenomenon is caused by man’s activities especially those that are aided by electricity. We need electricity to make life convenient but the improper use of it causes us to suffer from its effects. Also, one of the significant causes is the fossil fuel emissions that build up carbon dioxide in the atmosphere. “Carbon dioxide is released every time man uses his car, an airplane and a coal plant. Deforestation is another cause of global warming. When man converts the forests and grasslands into farmland and cities, it could not be avoided that there will be the release of carbon dioxide because man will burn the forests and grasses emitting carbon dioxide in the air.  All these human activities result to global warming” (Global Warning Early Warning Signs”, 1999).
C. Problem
Global warming is one of the serious environmental problems the whole world is facing today, which means the world is becoming hotter because the temperature rises to the level above the natural warmness of the earth. One harmful effect of deforestation is the lessening of the number of trees providing less oxygen to all living things. If the activities of man will warm the earth just enough, it will cause the carbon sinks to naturally fail.  Carbon is stored in the atmosphere for thousands of years and it is the “carbon sink”, a natural system that stores it. When carbon is released in the atmosphere, it will create a catastrophe to the earth. Another cause of global warming is the oceans which are no longer capable of storing carbon as they have in the past. Again, an ocean is considered a carbon sink, which holds even 50 times of the carbon as the atmosphere. Phytoplanktons, which store carbon dioxide, are dying at the bottom of the ocean because of the effect of global warming which in turn becoming less able to store carbon, aggravating the worsening climate change.
D. Solution
“We can prevent global warming by the following simple things to do. First, minimize the use of chlorine compounds. Examples of these are bubbles in plastic foam, spray paint, fire extinguishers, bleach and a multitude of discarded household and industrial chemicals. Other chemicals include phosphates found in many laundry detergents and soaps and should be avoided as well as aerosols such as fresheners and hair sprays which contain butane. Planting trees, using bicycles instead of cars in some situations, and minimizing the use of electricity are other simple things that can help” (“The Solution to Global Warming”, 2005). Processing of fossil fuel is harmful. Reducing the use of appliances, weather stripping, insulation and proper ventilation will go a long way to reduce the amount of heat that our homes need. Reducing the use of hot water will reduce also the amount of energy use, which is helpful in preventing global warming. On top of this issue, the harmful effects and the prevention will surprise all if they know that global warming has also useful effects. The temperature may change in a way that can help us. According to Global Warming Solutions”, 2008, “The greenhouse effect makes the earth appropriate for us to live.  Without the greenhouse effect, the earth might be frozen which means death to all living things or on the other hand, the earth might be burning hot also, which can kill all the living things as well”.
