After doing some studying on global warming, I think I can shed much more light on the topic. Well, the earth’s atmosphere has 4 layers. The Troposphere, Stratosphere, Mesosphere, and Thermosphere. I’ll be focusing on the Troposphere, and the Stratosphere. Alright, we’ve all heard about global warming, and I’m sure we all have an idea as to what it is.

If you don’t know: Global warming is the effect of the thickening of the ozone greenhouse air conditioner. It is caused by pollutants that are given off by factories, cars and etc. Due to the thickening of the layer, an increasing amount of sun rays/heat are being trapped in the earth’s atmosphere. (causing warmth)

Alright, now this is what most people don’t know. There are two Ozone layers. One is in the troposphere, which is the basically the air that surrounds us and the atmosphere which air plains travel in. The other ozone layer is in the middle of the stratosphere. Which is the next level above the troposphere.

Global warming comes from the ozone layer in the troposphere. This is formed from pollutants that are put into the air. These pollutants hang out in the air, form smog, and eventually heat our planet little by little (Green House effect). Usually green house gases are not bad because they keep the earth warm. But due to all the industrialization, these gases are building up and are becoming more harmful.

The Ozone layer in the stratosphere is extremely important to survival. It absorbs ultraviolet radiation, and allows for survival. Ultraviolet radiation is linked with skin cancer, premature skin aging, and cataracts. It is also know to harm crops, and kill small organisms such as plankton. As a matter of fact, in the 1970s scientist claimed that this ozone layer was being depleted. Scientist believed that the ozone layer was being destroyed by chlorofluorocarbons. A compound that was used in air conditioners, solvents and aerosol sprays bottles.

Back in the day, the use of sunscreen wasn’t promoted as much as it is today, due to the fact that the layer was sufficient enough. But today, if you stay out in sun too long, you’ll bear the marks to prove it. The layer is returning, but is still far from its original state.

Global warming is a life-threatening problem the world is facing today. It is a condition when the temperature of the earth rises due to the action of greenhouse gases like carbon dioxide, methane, and nitrous oxide. The emission of these gases into the atmosphere traps heat and light from the sun that rises the temperature of the earth. Though the issue has become life-threatening there are significant ways we can reduce its harmful effects. The most measurable step is to switch over to fuel-efficient cars that produce comparatively less amount of carbon dioxide emissions. As carbon dioxide is the leading cause of global warming, a drastic reduction of its emission into the atmosphere will be of great help to environment as well as to human life. There are other ways as well like insulating home, car pooling, planting a tree, and using more of public transportation.

Depletion of ozone layer is another alarming issue for the environmentalists. Ozone is an important component in the atmosphere that protects human from the harmful ultra-violet rays. Sadly, human activities have caused ozone depletion which can be disastrous if not controlled now. The key factor causing this depletion is the increase in the level of chlorofluorocarbons (CFC). In the stratosphere this compound breaks down to release a free chlorine atom that reacts with an ozone molecule to form chlorine monoxide and a molecule of oxygen. The resultant chlorine monoxide also reacts with ozone molecule to form a chlorine atom and two molecules of oxygen. The reaction keeps on repeating as and when a free chlorine atom is released. In the process amount of ozone in the stratosphere is drastically reduced which has become a serious concern. There are various ways to fight the issue like avoiding the use of aerosols, insulating home, and avoiding purchase of polystyrene products. It is also very important to keep a regular check of air-conditioner fitted in cars because any leakage in the coolant will release high amount of CFC.

Air pollution caused due to various human actions like smoking, forest destruction, excessive use of air-conditioners, and increasing reliability of private vehicles has considerably caused a serious threat to the environment. It is very significant to keep a control on the increasing pollution in order to save nature and life from the grip of destruction and disaster. To fight the problem the best ways are to use car pool or public transportation as much as possible, avoid both active and passive smoking, minimize the use of air-conditioner, stop the use of wood stoves, avoid purchase of formaldehyde products, remove asbestos if found anywhere at home, and make maximum use of energy-efficient appliances.
