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...

Global Warming

What is global warming? 

Global warming is when the earth heats up (the temperature rises).  It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.  This hurts many people, animals, and plants.  Many cannot take the change, so they die.

What is the greenhouse effect?

The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. As a result, the temperature rises.

Although the greenhouse effect makes the earth able to have people living on it, if there gets to be too many gases, the earth can get unusually warmer, and many plants, animals, and people will die.  They would die because there would be less food.This would happen because the plants would not be able to take the heat.  This would cause us to have less food to eat, but it would also limit the food that animals have.  With less food, like grass, for the animals that we need to survive (like cows) we would even have less food.  Gradually, people, plants, and animals would all die of hunger.  

What are greenhouse gasses?

Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun.  With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot.  As a result people, animals, and plants would die because the heat would be too strong. 

What is global warming doing to the environment?

Global warming is affecting many parts of the world. For example the ice of the poles melts and the sea level increases and cover low land and the plants and the animal die.

What do I think about this?
Obviosly this is an important problem. Many people think that this is a lie from de goverment but we can see the effects of these everywhere, one of the most notable problems are the strange weather during the seasons, on winter rains, on october it's too cold, the weather is crazy!
I think the things we do tying to stop this aren't very efficent, now I'm thinking what we could do.
Things that I do to stop the global warming:
- Recycle sheets of paper and plastic bottles
- Separate the rubbish
- Take short baths with not vey hot water

The Global warming is going to kill us! This are mi last words about this topic.
We'll lucky if we reach the 40 years old.
