Muhamad Yasir's notebook entry: Jan 03, 2011 Monitoring the concentration of greenhouse gases especially carbon dioxide (CO2) in Global Atmosphere Watch Bukitkotobang station, West Sumatera from 2004-2009 showed upward trend but still below the global average level of the world. Increasing concentration caused by increased activity of burning fuel oil, coal, and other organic materials which exceed the ability of plants and sea to absorb them. In addition, the deforestation, carbon emissions from vehicles, smoke from burning of homes and factories contribute to encourage the increasing concentration of carbon dioxide in the atmosphere. If the trend of increasing gases is still going on as now, increasing global warming will occur between 1.5 to 4.5 degrees Celsius around the year 2030. View of this fact, needed the awareness to reduce the increasing concentrations of greenhouse gases that cause global warming. There are several ways to reduce increasing of greenhouse gases and carbon emissions. First way to reduce increasing of greenhouse gases and carbon emissions are tree planting and forest rejuvenation. This is easiest way to reduce carbon dioxide levels in the air. Beside that, tree planting and forest rejuvenation that have been deforested could reduce increasing levels of carbon on earth. Thousand tree planting activities promoted by the government is one concrete step in order to reduce global warming. Simple steps we can do to participate in this program is to plant the green trees in the home environment, schools, and the edges of the roads around our village. This activity will be more effective if implemented to our younger generation earlier because it will foster our awareness of environment conservation. By growing concern for environmental conservation is expected to create a life balance between human and nature as a place their living. The next step is to reduce use of fossil fuel energy sources. The use of fossil fuel energy sources can increase the levels of carbon dioxide in the air. Changing trend of fossil fuel use from coal as an energy source which is then replaced by petroleum has indirectly reduced the amount of carbon dioxide in the air as carbon dioxide gas releasing fewer than oil especially when compared to coal. One source of energy that can be used as an alternative is nuclear energy. This is because nuclear energy does not release carbon dioxide at all. Besides the use of nuclear energy as an alternative, the use of renewable energy sources such as sunlight, wind and geothermal energy sources could be more environmentally friendly. The last step is to reduce the use of materials that trigger an increase level of carbon in the atmosphere by increasing the use of materials that environmentally friendly. As we know, the construction of large buildings recently increased quite rapidly. It turned out that the constructions of these buildings are very large impact on increasing global warming. Estimated that 70 percent of carbon dioxide (CO2) which flew into space arise because of the building. Therefore, the development of environmentally friendly buildings needed. Building an environmentally friendly form of green buildings is a building that it operations and process can save energy, efficient use of resources during the construction, operation, maintenance, and renovation. In addition, the use of non-organic materials for packaging food products must also be reduced. Wrapping food products made from plastic or rubber can not be decomposed by the soil so that it will cause the accumulation of trash and trigger an increase in the amount of garbage in the world. In brief, awareness to conserve the nature of this must be grown from an early age. This should be instilled by parents to their children as an example gets used to dispose of waste in place. Planting of this attitude is a real form of our awareness of nature that has provide many benefits in the form of agricultural produce such abundance. The form of activities to reduce global warming could be optimized if it gets full support from the government. The existence of clear laws and other policies that set conservation environment will help reduce the pollution that triggered the increase in global warming. So, protect our nature for our children.
