Swimming in CO2? NOT REALLY :)



Everybody has heard about the "pollutant" carbon dioxide, but only few people know the real meaning of CO2. Carbon dioxide is a colourless odourless incombustible gas present in the atmosphere and formed during respiration, the decomposition and combustion of organic compounds, and in the reaction of acids with carbonates (thefreedictionary). CO2 is just a significant part of the atmosphere, it's concentration is of 387 ppm (parts per million) which is about 0.038%, while oxygen is about 20.54% and nitrogen is about 76.55%. In the last 600 million years, this is the 2nd time the CO2 concentrations are THAT LOW! The first time was in the Carboniferous Period and the 2nd, now at days, named the Quaternarny Period. The CO2 highest concentration was during the Cambrian period 530 million years ago, with 7000 ppm! You can see it in the graph below.



Politicians and scientists warn us about thi "pollutant" which is actually nothing in out atmosphere, and it is NOT a pollutant, we need it to survive!!!! If we have more CO2, trees absorb it and produce more O2 (oxygen), humans breath in O2 and exhale CO2, and this is a cycle! As seen in the picture below, that white smoke is not polluting, it is just water vapor. People see this and think this is global warming, greenhouse effects, destruction of the ozone layer, and a lot more lies -).

Breathing Earth






This page I found is just a simulator where you can found the carbon emissions of each country and their born and dead rate. Why is this important to know this information? So that we can grow out consciousness of what is going outside our little world and notice how big the world is in reality and the way we are impacting on it. We have to take in consideration that this page is just a simulator, so it's not 100% accurate, but still I think it was a nice and creative idea to start with what can later be a more real simulator. As I entered the page, the first thing I noticed was that China and India are have a really high born rate and death rate, as well. Overpopulation can be a real big problem in the future, if our species continues growing in such a fast rate as it had been. However, that's the worst-case scenario, changes can still be made. For example in China, now there is a "One Child" policy, which the government is keeping an eye on closely. As resources are being used, more people are coming to the world, so how will we be able to sustain the human race if resources are scarce? That's a global problem that I think we should pay more attention to. Education and being informed are two powerful tools that can be used in order to combat overpopulation. If we had to go to extreme cases, we can apply policies not only to China but to India as well, which has a bigger birth rate.



Other important aspect that this page shows is our environmental impact each country made on the world. In each country we can see in how much time each country produces 1000 tonnes of CO2 emissions to the air. When I checked the data, I think that this simulator was lying, since for me the data it showed was too much. There's some information below on the page which says that the CO2 emissions that show the page were more probable to be too low than too high. Well, maybe the page is not 100% accurate, but sometimes truth is hard to swallow. Some of the countries that emitted more CO2 were China, Russia and the U.S.



In conclusion, I just thought that this page was a great idea to start with. I hope you have a look and decide for yourself if it's useful or not. I totally like it since it put things in perspective and one more thing: reduce has to become part of our culture so that we can continue living in this world with no side effects.
