From an animation movie, Ice Age, we figure out that global warming has started since once in a long while when Earth goes through a period of especially cold weather called an ice age. In an ice age, there are some periods of time which the weather goes warmer, called the interglacial periods. It could happen several times in an ice age. Even the scientists believe that the present period of time is only one of the interglacial periods. So, after this period, will there be another ice age period? Nobody knows, since an ice age isn’t a scheduled weather and period. If the ice age happens again, we could see the situation more or less just like in The Day After Tomorrow movie.
Why the rising temperatures these days give us so much trouble? According to the scientist, the interglacial periods occurred at roughly 100,000 years intervals. It caused by the increasing of the greenhouse gases such as carbon dioxide and methane naturally in the atmosphere. But the increasing of the greenhouse gases these days not in the level of 100,000 years. This extent changing is quite shocking. Human population growth and activity and the development of technology has made this natural phenomenon goes quickly than we expected. When the greenhouse gases are rising, the temperatures are following. That’s why the Earth goes warmer, and the latest discovery, the temperatures of the Earth have risen for about 2o Celsius. In this rate, many life of plants and animal cannot survive, the rising sea level, and there also the rapid changing of weather suddenly and even climate changing. To human, this could cause disease, failed crops, and disasters like flood, storm, etc.
We’ve known that human contribute a great damage on Earth and causing what we called global warming. Our ancestors change the atmosphere started hundreds of years ago when people cutting down forest and burn the wood. The invention of cars and other machines greatly increased the amount of greenhouse gases released into the atmosphere. Such machines burn fuels like wood, coal, oil, and natural gas. When these fuels burn they release carbon dioxide to the atmosphere and methane comes from coal producing.
The development of science and technology make people these days more aware with this changing. They started to do things to reduce or even stop global warming. They do campaigning, planting trees and fundraising to grow more forest and even international agreement due to stop this issue. Of course, we, as forestry students and teenager of this changing era should take part in stopping global warming. There are so many things that we could do in our everyday life as our action to stop global warming such as follows:
First, we are in a problem of gas emission. So, we should reduce the gas emission, especially the greenhouse gases which are produced from the burn of fossil fuels by reducing the intensity of using private machine vehicle such as motorcycles and cars. Use the friendly environment vehicle such as hybrid cars, bicycle, or use public transportation, or the best way is walking. Walking is not only good for the environment but also good for health.
Second, we also run out of fossil fuel, so we should use the other energy source. Technology nowadays has resolved this problem by utilizing solar energy, wind energy, and even now, the utilizing of Earth heat energy has been developed.
Third, there are some materials the Earth decomposes it in years, such as plastics, metal, etc. but for Styrofoam, Earth nearly cannot decomposes it. So, what we should do are reducing the uses of that kind of materials or reuse the things which are made from that kind of materials, or with some creativity, we could change some things into another useful things or tools. That is called recycle. The ‘3R’ reduce, reuse, and recycle is one of the program to fight global warming. Some of supermarkets even prepare fabric shopping bag to reduce the production of plastic, and the shopper should bring fabric shopping bag for shopping. For the students, papers are mostly used thing, but they come from trees which is valuable for carbon stock. So we should reduce the using of papers by only printing the important thing, use second-hand papers, and recycling the papers.
Fourth, the weather and climate change could harm our health. We should keep our health to the fullest to fight global warming. So, we should eat nutritional food, especially fresh food, reduce fatty food and junk food, eat more vegetables and fruits, drink fresh water, and if needed, have some vitamins to maintain our immune system. We also should maintain a healthy lifestyle; no smoking, no drugs, no alcohol, and reduce caffeine.
Last but not least, plant trees. Trees could absorb carbon dioxide from the atmosphere and produce oxygen. The increasing amount of oxygen in atmosphere could cool down the air. Trees store the carbon in their stem and whole part of them. Protecting the existing trees and forest are also important. They have stored the carbon in their whole body and if we cut them, we release the carbon to the air and it could make the temperature rise. We also have to tell the other people to concern about this matter because without everyone’s action we cannot fight global warming. We should work together to stop global warming and save our lovely Earth because it’s the one and only place we can live in!
