Hi C.R.I.A. Online and members of the C.R.I.A.

I liked to leave a message here.

I wish you all a good school year and to study very english.

And I leave a hug for the teacher José Mota.

This is our work about the McDonald's.
Please comment and watch until the end.
It's very funny.

An interesting question, unanswered by humans. Every day somewhere on the planet thousands of people make this question, but don’t get answers. Some say that what we are living now, is a way for us to accept and when we have started preparations.
We all know what is life, despite being a concept very long, we all have a concept. And death? What is death? Well death is the termination of life. These two concepts, today, are much discussed, but there were still definitions for them, but for me are all incomplete.
All human beings have an average age of life, and all other living organisms. But after that life comes death. How is it death? Would we? Are we will feel alive again? We don’t remember when we had 1 or 2 years. Is there reason for the awareness of these questions? I think yes, could contribute to a large development on a global scale, to the knowledge of mankind, which is so mysterious.

The atmosphere is the gas layer surrounding the Earth. It consists of a series of gases that play a very important role in moderating the temperature at the land surface.
The atmosphere works like a greenhouse, that is no longer spend part of solar radiation, but prevent the land leaving radiation into space. The gases that constitute this layer doesn’t leave out the solar radiation are: water vapor, carbon dioxide, CFC, etc., is called the greenhouse effect gases.
But we, humans, we are doing that with the greenhouse effect increase, because the human activity and pollution, so that there is a greater concentration of gases in the atmosphere, soon more the greenhouse effect.
This goes bring serious consequences to the planet, such as: the melting, the change of climates, the temperature increase, soon the rise in sea level and in turn the consequences will connect to global warming.

P.S. Some ideas of the book "GEO Environment and Society."

As we know, our planet is surrounded by a large gas layer - the atmosphere. Ozone is one of the gases in the atmosphere that exists. But it is between 20 and 30 kilometers (in the stratosphere) that we can find a greater concentration of this gas.
Ozone is a natural filter very important because it absorbs the ultraviolet radiation emitted by the sun, which are dangerous for living beings; the ozone layer is thus the immune system of the Earth.
The destruction of this layer can have negative effects, such as: the increase in cancer of the skin and problems of vision; the risk of genetic changes in living organisms and flaw in the immune system.
What it doesn’t have to take measures, such as: use only aerosols that have not CFCs; encourage people to have refrigerators, chest, etc. ecological. Because the CFC are gases and are the main destructive of the layer of ozone, which when released into the atmosphere will react with the ozone, causing its destruction.

The Earth as I said earlier in my other text "Earth, a very special planet" has beautiful characteristics, in this text I will talk about the diversity that exists on our planet.
As you know, our planet is the only one that allows the development and the existence of living beings. So perhaps the great diversity of living things we have now is one of the most interesting characteristics of the Earth.
This diversity, it is necessary to preserve, trying to understand its ecological importance. But the violent human intervention, the overall evolution of Nature and the list of threatened ecosystems can’t leave us indifferent!
Diversity is based mainly on the characteristics that are allocated to those living beings, such as the structural aspects of the same living being.
Therefore, we must continue to take steps to preserve our "ecological heritage" so that our successors can see how beautiful our planet, in terms of Biological Diversity is.

In 1960 we saw the first time, the picture that perhaps has had the greatest impact: the Earth seen from space. Previously, it wasn’t possible to truly understand that the Earth is actually a small body with a planetary orbit around a star of average size, the Sun.
The history of the Earth has been a great series, which is the history of the Solar System, and that an even greater, which is the history of the universe.
The Earth, however, has special characteristics and unique compared to other planets in the Solar System.
These are characteristics that have allowed the existence of a great diversity of living things. But, in recent years, have been an uncontrolled increase of pollutants in the atmosphere, hydrosphere and in the soils.
This increase wonders in the capacity for self-regulation of the various subsystems.
Living on Earth means taking advantage of the resources in a sustainable way by successive generations.

Hi...
I wish you all a Happy Year 2008 with great health and joy. How come everyone on the right foot.
For all a HAPPY NEW YEAR.

In my opinion volunteering is a nice action, because it envolves cooperation, interaction and communication with other people.
Increasingly, volunteering is increasing, and in other countries it can develop our linguistics skills; legde of cultures; news places, but to be a volunteer, we need to be responsible; a good communicator, to help other people and show your good exemple.
