Global warming
Every time we drive the car, we heat our house, turning on a light or cook, we produce carbon dioxide, the gas mainly responsible for the greenhouse effect and global warming. Experts say that global warming may alter substantially one third of the habitat of plants and animals by the end of this century. Climate change may lead to the extinction of about one million terrestrial species in the next 50 years. Sea levels will rise, the atolls will disappear and some places such as New York, will become similar to Venice (Venice and end up like Atlantis?).
The WWF launched in 1994 the alarm about the phenomenon of climate change, but in those years the public was not yet convinced of the seriousness of the problem. Seemed a threat of the future, something less tangible and far from everyday life of everyone. Not so!
It is now clear that climate change and, thus, global warming, are threatening entire ecosystems, endangering life as we know because of the intensity and frequency of so-called "extreme weather events (hurricanes, floods, waves heat, etc..). Rising temperature by the rising sea levels, desertification, melting glaciers, the alarm is now at the highest level.
The magnitude of the occurrence and severity of expected impacts have led scientists to speculate on the need for a kind of new industrial revolution based on the gradual surrender to those resources which, despite having guided the development of technology to this day, can be considered the main cause of climate change: fossil fuels.
To prevent, in fact, that the climate of our planet within a few decades can enter into an irreversible crisis, such as to render impracticable any possibility of adjustment for most of humanity and other living species must be reduced by 2020 emmissions of carbon dioxidw and other greenhouse gases by 30% and, by 2050, by 80%.
