Human Activitiy Causes Climate Change Essay - 991 Words

An American vice president, Al Gore, said that while the reason behind dinosaurs’ extinction over 65 million years ago was because of a giant asteroid, the species that are dying out every minute of our lives are not just because of some havocs, but it is US-human (Al Gore, 2006, internet). We are destroying our world indirectly which means we do not just go and kill those entire animals, but what has caused their extinction is due to â€Å"Climate Change† that is the result of the Natural Causes and Human Activities. We used to look at how natural causes have contributed to climate change, but human is now even playing a bigger role in causing climate change. Climate can be defined as the average weather effected by slow features such as†¦show more content†¦Therefore, as we can see nature has made a lot of contributions to the climate change; however, what they have been doing for these millions of years has already been adjusted by the world’s balance . Human, on the other hand, is the main cause of the consequences of climate change, especially in the 20th century, counting from the industrial revolution. Just the same as nature, we also release gases such as CO2 to our atmosphere. Some examples of these activities are the burning of fossil fuels and contaminated emission from factories and cars. Looking at the figure above, we can see that the emission of CO2 from ocean and vegetation range as high as from 332 to 439, but at the same time they absorb CO2 at a similar amount they release. Then again, the burning of fossil fuel and land use, only liberate as much as 29 amount of CO2 to the atmosphere, a very tiny amount compared to the ocean or vegetation. But, the question is why we are the main character that causes climate change? Unlike natural causes, man-made contributions to climate change are not a cycle, but a one way on-going process. We are releasing those harmful gases into the air, but at the same time never do anything to dissolve them back to maintain the atmospheric equilibrium. Our actions are causing extreme weather condition; meanwhile, the main concern that has been attracting a lot of awareness lately is â€Å"Global Warming†- the increase in global averageShow MoreRelatedSocm Study Guide Essay30404 Words   |  122 PagesChapter 1 ELO’s Describe the basic functions of living organisms.
