larger and sun's UV rays would pass through the earth and the earth would get warmer. Moi : The humor of this cartoon is the huge contrast between the sentence he utters, and the situation where they find themselves. Indeed, it is an ironical situation because the character fears the global warming whereas he finds himself in a snowstorm where it's very cold. Rather, he should have been expressing the fact that propaganda tells us that the earth warms up, while here it is very cold. Toi : The

débute en octobre 1968 avec l'exposition intitulée Earth Works, à la Dwan Gallery à New York. Avec la publication de son essai The Sedimentation of the Mind: Earth Projects en 1968, Robert Smithson s'impose comme le théoricien du Land Art et devient la figure emblématique de cette tendance artistique, aux côtés de Robert Morris, Nancy Holt, Dennis Oppenheim, Walter De Maria, Christo et Michael Heizer. En février 1969, une autre exposition, Earth Art, organisée par Willoughby Sharp au Andrew Dickson

uranium used in nuclear plants is not bottomless, and moreover it contaminates tremendously. Indeed, the created waste is not recyclable and must be buried. So, we need to change our behavior and to have better electricity solutions with which the Earth would be preserved. Introduction Ideas of technology Video Conclusion Solar energy We can use solar energy to produce electricity.

shared hope, this diverse group of peoples asked the questions that have been largely absent in international meetings: What are the structural causes of climate change? If the human race is to survive, how must it re-think its relationship with Mother Earth? How can we as human beings collectively end irrational industrialization and consumption to cease provoking irreparable harm to our environment? In seeking to address these important questions, the human race can benefit from the wisdom of the

because we can already see the consequences of global warming on Earth. For example, we can see that the polar ice cap is melting step by step wich provokes floods and wich raises sea levels. In the movie "une vérité qui dérange" we can see that beacause of this greenhouse effect some areas of countries could disapear under water. It is not harmless to considere that we are unstoppable. Humans forgot that we are on Earth and Earth is a planet not an empire. Gas, coal, nuclear energy aren't clean

to recover steam and therefore to drive gas turbines. Our system will consist in heat our salted water to evaporate salt. INTRODUCTION 1) The solar energy received on Earth The Earth is located 150 millions kilometres from the Sun. It delivers 1026 Watt continuously in the form of radiation and the Earth received 178 million billion Watt on its face enlightened or 350 Watt per m2 at the equator. The solar radiation is electromagnetic radiation consisting of mainly: • Visible

impact on our environment and earth ? Is regulation necessary ? We all know that electronic products like computers become obsolete quickly, like we saw in the document, these products are full of lead mercury and cadmium. When we know that, we can understand why the stakes of recyclingare very important for our environment, the earth and people who live on it. We all have to be aware of what can happened if we are not more respectful of environment, ressources on earth are not unlimited, there is
