The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sunlight in to make heat, but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts, and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane, which comes mainly from animal manure. Other gases like nitrogen oxide and chloroflurocarbons, man made gases, get caught in the atmosphere as well. The decay of animals and respiration are two main natural sources of carbon dioxide. In my opinion, we the people of the world should try to slow down the emission of greenhouse gases and/or find ways to balance the gases so the climate doesnt change so rapidly. If it did, we would be forced to adapt to the new climate that we brought upon ourselves. If we had an international cooperation to put a damper on the production of chloroflurocarbons and slowed down the use of fossil fuels it would dramatically slow done the process of global warming. Carbon dioxide pollution from the increase of industry and transportation is a major cause of global warming. These two causes are connected with the growth in the world population. As the population grows the necessity for food and other products increase, therefore industry must grow to keep up with the demand. The increase in transportation is directly due to the growing population and the need for jobs and the growing congestion on our highways. Another cause in global warming is deforestation. Trees remove carbon dioxide from the air as they grow. The carbon dioxide is released back into the air as they are cut and burned. The forest ability to reduce the carbon dioxide from the atmosphere is decreasing due to massive deforestation around the world. These causes seem simple and fixable, but if they are not cut down, the Earth and its inhabitants will feel the effects. greenhouses for sale
