In fact, in 1966, he was the one to establish the « Beach Bill », which declared Oregon State owner of 480 kilometres of seaside. Thanks to this project, today, we can observe untouched and clean white-sanded beache

Did you ever think that Inuit people could invent a new word for sun burns? Because of the global warming, they have done it and the result is: uunnitaaqtuq. You could find it funny, but the situation in polar caps is extremely critical and catastrophes are accumulating. Indeed, the Artic ice floe, in about forty years, will become a little layer o

The availability of its resources depends on the quality of the sea ecosystem, which is threatened by 3 factors: The pollution due to hydrocarbons: Illegally,

To my mind, this is the most visible consequence of the global warming. It damages everything! For example, indigenous people have to migrate to survive and I think it's shameful to let them leave their homes. I think it's as if we pushed them away although they had done nothing to deserve this situation. It destroys the habitats of biodiversity ly

In tropical countries, the deforestation is catastrophic. In the early 1990s, the situation improved but now the situation is getting much worse. It’s necessary to stop that at once!

The world is composed of 70% of water and yet a lot of countries are touched by drought. I really find it unacceptable to waste so much water. We don't think of the other persons when we stay 40 minutes under the shower, do we! In fac

Since 1870, the glacier have been melting. Indeed, the glacier of Argentière and of the Mont Blanc moved back respectively of 1150m and 1400m, as well as the Alps, which -between 1850 and 1870- lost almost of third of it surface. This melting is provoked by the global warming and the greenhouse effect. The global warming is the mainspring of the a

What is the answer to stop the depletion of the resources of the planet ? Resource depletion occurs when all of the natural resources, both renewable and non-renewable have been exhausted. Actually, human beings currently use resources far more quickly than they can be replenished. A good example of resource depletion is the growing use of petroleu
