HEAL THE WORLD
Of all the problems facing the environment today, global warming is the biggest and most serious problem that we need to take care of. Global warming is an increase in the average temperature of the Earth's atmosphere, which results in changes in the climatic conditions. As greenhouse gasses such as Carbon dioxide, Methane, and Nitrous Oxide in the Earth’s atmosphere increase and gets in our Ozone Layer, it creates a blanket of gas that traps radiated heat and prevents it from exiting our atmosphere. As a result, temperature rises. On the other hand, there have been many doubts about the validity of global warming. Many skeptics argued that global warming is a natural cycle and people have nothing to do with it. Most of them even think that global warming is not occurring, they believe that climate models used to establish global warming and to forecast its impacts are not accurate. However, the truth is, global warming is really happening right now. Based on the Intergovernmental Panel on Climate Change (IPCC) report, “the average temperature of the globe has warmed from about 13.50 C to 14.50 since the beginning of the 20th century” (Dire Predictions 36). IPCC surely brings the most reliable projections for future climate change and its potential impacts. “The reports are written by thousands of the world’s leading scientists” (Dire predictions 8). Nevertheless, even if we consider the idea that global warming is something that naturally occurs on earth, climate has never warmed up at this high speed. In fact, humans are the core reason it is occurring; the rapid increase in development of cities and technology has raised the amount of greenhouse gasses in the atmosphere. The advancement in technology has led to population increase and industrialization. To provide housing for the increasing population, we have been cutting down uncountable forests. And when forests disappear, the land loses the ability to absorb carbon emissions from generating electricity, cars, and factories. We have been so focused on finding ways to make our lives easier that we have forgotten to take the environment into consideration. In order to save the planet and its inhabitants, everyone has to take the responsibility to stop global warming. We don’t need to be influential or powerful to reduce global warming, even college students like us can give significant positive impacts just by doing simple things such as consuming less electricity, emitting less fossil fuel pollution through riding bicycles and walking short distances, reducing the consumption of newly made goods and persuade others in following our actions. As the earth's atmosphere gradually warms, it is affecting everything from sea levels to the weather and ecosystems around the globe. With the high temperatures, the polar ice caps could melt and cause the sea water level to go up. “The sea level is currently projected to rise between 0.5 m and 1.2 m by 2100” (Dire Predictions 98). This would lead to huge flood that could take out small islands and some coastal cities around the world. There would also be less rainfall in numerous places with the result of drought and severe forest fires. Moreover, this extreme changes in the weather and environment would put a lot of species of animals and plants into extinction. For example, the Polar Bears in the Arctic are being threatened by decreasing ice caps, they cannot eat food because they cannot find land to eat it on and do not have place to rest. When the plants and animals die, people lose two sources of food, plant food and animal food. Food crisis would lead to increase in food prices and even death for people who cannot afford it. It is like a chain reaction, one thing that leads to another and so on.  Global warming also affects people’s health. For instance people with cardiovascular problems are mostly affected by increases in temperature and many have died because of heat wave as well as exhaustion problems....
