Polos

The melting of the poles threat the climate in Mexico.
The polar melting is a phenomenon produced because of the global warming known as greenhouse effect,which consists in that determined gases, that are components of the atmosphere, retain part of the energy that the surface produced because it has been warmed bythe stellar radiation. Affects to every planetarium body in the atmosphere. This phenomenon avoids that the energy constantly received go back immediately to thespace, producing a similar effect observed in a greenhouse.
According to the most of the scientific community, the greenhouse effect is seeing increased on Earthbecause of the emission of certain gases like the carbon dioxide and the methane, because of the human activity.
To can avoid that the global warming continuemelting the poles, we have to stop producing the gases that cause it using in a minor quantity de car, use more the bicycle when traveling short distances orwalking, avoid the use of aerosols, this contains chemicals that affects the atmosphere, control the felling of green aereas, cutting only old trees and plantingnew ones, these trees help use to convert the carbon dioxide into oxygen and will reduce the proliferation of theses gas in the atmosphere.
In my opinion these isone of the most dangerous problems because it not only affects human but also every living thing on Earth.
The physical and chemical changes I identify is howcertain gases as the carbon dioxide can cause many damage like making a hole in our ozone cap and that this same heat that enters by this hole can’t go out.
