Recent studies put on the table that the increase in environmental pollution harms to the learning of people, more specifically of children of growing age. The team of scientists from the University of Colorado at Boulder, together with the Colorado School of Public Health and the University of Pennsylvania, has concluded that the cognitive abilities of children, since they are of growing age, can be affected negatively because of the high levels of carbon dioxide present in the atmosphere today.
Surely you have heard of it a hundred times but you may not know how to define carbon dioxide. Carbon dioxide, in its acronym CO2, is a chemical compound (colorless gas) that is made up of one atom of carbon and two of oxygen. These elements exist naturally in the atmosphere of our planet. However, today it is also known as greenhouse gas for being one of the most relevant polluting effects since the burning of carbon fuels of the Industrial Revolution, mainly due to the fact that its levels in the atmosphere have increased. what gives like consequence of global warming.
As noted in the Phys.org report that we mentioned above, we are all already facing the well-known phenomenon of global warming. This is due to the large amount of CO2 emissions that are released into the atmosphere. But you already knew this, right? What you may not know yet is what this group of researchers have discovered. Scientists have concluded that as CO2 levels rise, human thinking becomes increasingly confused. We have before us another negative effect of climate change that is already causing problems for children and adults.
Scientists have tried to analyze in their research the problem posed by the increase in CO2 levels in the air we breathe, the one that our children breathe without going any further. It has been seen, in these and other previous investigations, that environmental pollution can trigger various cognitive problems.
According to the data collected in this study, the cognitive abilities of school-age boys and girls will decline by 25% by the next year 2100. The worst data indicates that they could be reduced by 50%. Why so much difference? Well, that significant difference lies in what human beings do from now on. Sure that you also open the window of your house or your class every morning to ventilate and let fresh air enter from all corners. Well, the question that scientists have asked is this: what happens when the fresh air that enters a house or a school has high levels of CO2?
To try to answer this question, the same model was created with two possible results. In the first, people will commit to reducing emissions into the atmosphere of gases as much as possible. And in the second, we won't do any of this. Now you surely understand that difference between the positive result, the one that indicates that students' cognitive abilities will decline by 25% by the next year 2100 and the result that the researchers have qualified as negative and that shows that these capacities will be reduced by no less than 50%.
On the other hand, a study published in the Proceedings of the National Academy of Sciences of the United States of America, entitled 'The impact of exposure to air pollution on cognitive performance' adds that the damage from exposure to polluted air increases as people become make older. The brains of older men, especially in cases where their educational level is lower, are affected to a greater extent and more negatively.
What is it worth trying everything to ensure that this percentage is reduced to its minimum expression?
Experts warn of the importance of put an end to polluting CO2 emissions to the atmosphere. Only in this way can the cognitive abilities of children and adults be unaffected.
With recent research it is clear to us then that pollution can affect the cognitive abilities of children, however, there are still two other negative effects that we cannot stop paying attention to.
1. Breathing air with high levels of CO2 aggravates respiratory diseases and cardiovascular. This has been demonstrated by the European Environment Agency (EEA).
2. Several previous studies have shown a direct relationship between disorders such as autism, attention deficit hyperactivity disorder or dyslexia due to the group of neurotoxins, such as lead, methylmercury or toluene present in polluting gases.
It is in everyone's hands to try to solve this serious problem, do you sign up?
