What is global warming?
Global warming is a worldwide problem we are now staring in the face. Human beings have caused this by creating carbon dioxide and greenhouse gases, which builds up our atmosphere, until only the Sun’s powerful rays will penetrate it. Unfortunately, our atmosphere is like Earth’s insulation, which means it will prevent the heat escaping into space. Over centuries, this heat will build up, slowly torturing vegetation, animals and human beings. The worst part is, it’s already underway.
Firstly, what are the causes of global warming? Our atmosphere is a gargantuan sphere made up of gases, blanketing Earth. Without it, the Sun would roast us by day, and we would be frozen solid by night. But by building up our atmosphere, mainly with carbon dioxide and Greenhouse gases, we are damaging our planet. Basically, it’s like adding more and more insulation to your home, meanwhile increasing the heat inside. We produce carbon dioxide by petrol fumes from vehicles, fires, smoking, and even breathing. We breathe in oxygen, and breathe out carbon dioxide. However, trees are the opposite, so felling trees is a big problem too. Petrol fumes from vehicles is mainly our biggest problem. People are driving to local places that would have only taken five more minutes to bike to. This is not good for our environment!
Subsequently, what are the consequences of global warming? For a start, the Polar Caps, the South and North Poles, and Antarctica will melt. Cute penguins and polar bears will be homeless and eventually will die out. Also, with all that melted water, the sea level will rise enough to at least drown islands and coastal towns. The weather will change dramatically. Whether it is frequent thunderstorms or terrible droughts, crops will not survive. Unless we find some sort of food source able to survive global warming, most animals (including human beings) will starve to death. Although this is a terribly slow process, taking many thousands of years, the human race will die out eventually, which will be an improvement in some ways and a catastrophe in others. Some animals will survive. Earth will not be devoid of life, because some life will have adapted and evolved to suit the environment.
Thirdly, what can we do to help prevent global warming? One of the main, and probably most effective, things we can do is not produce much more gases harmful to the environment. It’s best if the atmosphere does not get any thicker than it already is. Simple yet effective things anyone can do is bike or walk instead of drive. Don’t cut down any more forests than we really need. Riding on buses reduces the amount of petrol fumes released into the atmosphere. If twelve people each took a car that would be twelve lots of fumes. However, if they went in groups of four only three lots of fumes would be produced. If everyone acted, it would be simple things like that that made all the difference.
In conclusion global warming is a worldwide problem. Not fiction, it’s reality. Some people will say, “Global warming is a myth. Don’t be concerned about it.” This is not true! We can help prevent the horrible consequences if we do simple things. Now that you know what global warming is, what the causes and effects are, and what you can do to help, PLEASE cooperate! A little consideration for the environment can go a long way!
