Global warming is one of the most serious problems in the world in our times. The main reason for it is the large quantities of CO2 in the atmosphere from factories and cars and the tones of rubbish in the lands and the oceans.
There are many problems which are caused by the global warming problem. Firstly, the CO2 in the atmosphere increases the temperate of earth and the ice of Antarctica and of the arctic is slowly melting, with the danger for a lot of cities to flood, and the (plastic and other) rubbishes and the wastes of factories end into the seas and oceans with the result the water to be rubbished and poison all the animals of the sea.
In order to be faced the global warming, alternative energy sources must be used (solar panels, wind turbines and hydro-electrical energy) and electric cars, we must recycle and the rubbishes must be managed, correctly.
We must be interested in global warming and we must be careful not rubbish the environment.
