Greenhouse_Effect

Greenhouse Effect In the past month, a huge number of politics, journalists, activists, and also scientists moved to Copenhagen, in Denmark, to participate in the greatest Summit about environmental issues ever organized.Along with, the politicians, who tried to find a compromise on the footprint's reduction in the industrialized countries, the scientists tried to understand more the implications and the aspects of the greenhouse effect, considered as the main cause of global warming. However, why did the scientists focus especially on this issue' What are the consequences of this global process on the global ecosystem' And what are the possible solutions' In the first place, will be explained how a number of natural mechanisms and human activities lead to the greenhouse effect , to clarify in a second period the consequences of this process on the planet, and then to shade the light on the possible way the solve this problem. First of all, the greenhouse effect can be described as the penetration of sunlight through the atmosphere, which causes the ground to warm. In other terms, it’s an occurring phenomenon that is responsible for catching heat near the planet's surface and keeping the earth warm. This global phenomenon is very ancient; however, it has only recently been in the news. More than that, it’s commonly considered, especially in the mass media messages, as a result of the fast growing carbon dioxide and methane emissions over the last decades. In fact, it has been increased, but not created, by the industrial activities. Theses economic activities are leading to a climate change due to their utilization of fossil fuels. Not only the transcontinental corporations and developed countries are taking part of the greenhouse effect’s increase, but also every car user or every farmer owning a huge number of cows, blamed for the high methane’s concentration of their biological emissions. Consequently, the greenhouse effect is not merely caused by nature but many human activities. The fast rise of the economic resources exploitation and the use of economical process to cut the production costs, are leading to dramatic climate’s changes. Over the last century the global temperatures have been increasing slowly but gradually, which menace actually the arctic pole and can cause a sea’s level increase. Furthermore, animal species demographics are changing all over the world. While some species, like the whale, are about to extinct, other are migrating from a part of the planet to another. In addition to that, the global warming causes deep climates changes. As result, a multiplication of climatic catastrophes affecting all the part of the planet, from Katrina’s hurricane in USA to the droughts in the Sahel. As the ex- Vice President of the USA, Al Gore, said, the greenhouse effect is” the potentially most dangerous environmental problem facing mankind”. Consequently, peoples all over the world must cooperate to avoid a global disaster. The economic development and prosperity of some countries should not be on the account of some other people’s lives. In spite of the recent failure of Copenhagen summit, the global treaties and agreement are the most effective way to solve the problem of global warming. In addition to that the local actions are considered as the first step to greenhouses gases emissions reduction. In fact, reducing the use of the car or buying more products respecting the ecologic requirements, are microscopic actions that lead to macroscopic changes. As we have seen, the greenhouse effect is a global phenomenon affecting the whole planet without a distinction between a poor or developed country. To face it, the humanity needs to think in a new cooperation’s ways. As consequence, can the efforts of facing the global warming challenge, be the first attempt to unify the humanity'
