Nowadays, we are witnessing a very serious phenomenon: Global Warming. This phenomenon is characterized by the rise of the medium temperature on the globe surface. A great part of the scientific community believes that global warming is caused by the rise of polluting gases concentration in the atmosphere.
The atmosphere is the most vulnerable part of the Earth’s Ecological System because it’s so thin, but in the last years it is becoming thicker due to pollution and greenhouse gases which keep the heat there. That is what we call greenhouse effect.
Scientists are really worried about our future as a species because it has been threatened by the human pressure on the Earth’s Ecosystems. Actually we can witness some of the consequences of Global Warming like the melting of glaciers, the rise of sea level and stronger storms like hurricanes, tornadoes and earthquakes, so it should not be only a worry for scientists but also for all citizens. If we don’t change our habits in order to reduce greenhouse gases emissions and to protect our environment the consequences of this phenomenon will be even more dangerous and catastrophic: the Earth’s coastlines will be flooded, which will displace millions of people, some animal and vegetal species will disappear, storms will be stronger and will happen more frequently, there will be more droughts and, paradoxically, more floods.
So, it is urgent, important and essential to change our habits to revert this situation and to save our future as a species.
