Many years passed since the world started to understand the global warming phenomenon. Technology and science provided theories, excuses and causes of the global warming...and still keep producing new evidence about the current status and the possible threats for the humankind. However, the changes we observe almost every year since then, are the hardest proof that the environment is reacting to human intervention. When we see old movies in the TV and we see how in early 1900s the people lived and how the cities were small pieces inside forests, by the deep blue sea, by the rivers, we conclude that we occupied nature and now forests, sea and rivers are the small pieces by the cities or generally by the human occupation. Fires, floods, pollution, deforestation are broadcasted by the media every day now. Eco-news, eco-shows, eco-reality, eco...eco...eco. The eco- compound in words is now "cool". It is "cool" to buy eco-tshirts, eco-food, to drive bicycle, hybrid cars, to donate money to reforestations, rivers renaissance, to eco-campaigns. Well, it may be the truth that people now are more sensitive in ecology matters, which is indeed a very good and positive view of human action, but do the people really know what happens to nature, what happens in earth's crust? Are the people sure that mankind caused the global warming and changes in the natural environment?
