GlObal Warming

... in a nutshEll 

       Our planet has a natural proces of warming called "Greenhouse effect" which allows a thermal equilibrium, keeping the Earth just warm: not too cold and not too hot. This is a great point to make possible the life here.    
      The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases ( water vapor, carbon dixide, methane, nitrous oxide, and ozone), and is re-radiated in all directions. Since part of this re-radiation is back towards the surface, energy is transferred to the surface and the lower atmosphere. As a result, the temperature there is higher than it would be if direct heating by solar radiation were the only warming mechanism.
    But the indiscriminate acts of humans such as  deforestation and burning fossil fuel causes the increase and the concentration of greenhouse gases, from this, the atmosphere: the ozone layer becomes thicker (in some parts it breaks up), if this happends, the greenhouse effect can't work completely correctly, because of the thick of the ozone layer the re-radiations can't go out through the atmosphere again staying in Earth increasing the global temperature. This is called Global warming.
      If the global temperature increases, the poles may metl increasing the ocean level sinking many cities; many species may die, causing alterations in the food chain; in some places may never rain again, causing droughts; the weather may change everywhere, wars ie: death, just for mention some consecuences.

WHAT I THINK ABOUT...

_ Markedly, this is a big real and heavy problem which includes many other problems and affects all of us, everyone: all the world.
Some people think this is a goverment lie; others think it's just a Green Peace business; others: "They exaggerate a lot"; others no even know about; others, sadly, know about, know the seriousness of the matter but they don't care; others belive in this and try to do something about and finally others think the Global Warming we are perceiving is just another world's stage which every thousand of years it goes through. It's true, another stage in the planet's cycle,  another... again... but this time! this time is different: this time it's up to humans to live, to feel the change. And What's involved? droughts, melting, climate changes, deforestation, depletion of natural resources, famine, war, death, animal extinction... human extinction... What's the matter? It is supposed to be like this, many species die, humans die, ant there's a new beginning, new life, so?

Of course humans don't like even a bit this point of view.

-> How could the "human race", the "homo sapiens", the "rationals", the "intelligents" ones could die? -We're the best thing that ever has existed in Earth, we can't die <- people think...
Our proud is bigger than ourselves. We are unbelievers, we are lazy, we are little princesses, we think we're undefeatable, we don't want to get our hands dirty, we are "too much" for everything...
Everybody wants to change the world, everybody wants to save the world, but no one wants to "get hands dirty", no one wants to die... so What will save us?! 
-We- only we can, but now this is in doubt. We can't improve with this mind!! 
There are too much to do with the air, the environments, the * garbage, our behavior, our thoughts! This part is the hardest of all of the above mentioned, and the rest of no mentioned.
...if it is supposed that we're the "intelligent race", let's act intelligently! Let’s ACT!! Everyone knows what to do and (as said) no one wants to die.
Maybe... just maybe despite we really make a difference and die because of the -cycle-then it won't be a mediocre dead, then we had died trying...
