Blir vi verkligen dummare av högre halter av CO2? Vi har läst om detta förut. Nu har det gjorts en studie, som ger stöd åt misstanken. Om högre CO2 minskar syrehalten så påverkar det förstås våra förmågor. Studier på råttor visar att hjärnan försämras.
Studien tycks inte vara expert-granskad än, men resultatet är ju ändå värt att begrunda på allvar. För som det står i slutet: Det är dumt att tro att vi INTE skulle påverkas av vår omgivning. Ändrar vi omgivningen, så påverkar det självklart våra förmågor.
Study Shows How Pollution, Climate Change Could Make Us Dumber
Will pollution create a downward spiral of stupidity?
If our society is being dumb for not taking more urgent action about human pollution and human pollution can make us dumber, will we get to a point to where we can’t even understand how stupid we are being?
…
While these observations were associations, which don’t necessarily prove cause-and-effect, there are scientific explanations why higher CO2 levels may affect thinking. The alveoli in your lungs exchange oxygen that’s in the air you inhale with the carbon dioxide that’s in the blood. If the air that you breathe has more CO2 and less oxygen, then your blood won’t get the same amount of oxygen.
Oxygen, in turn, helps your cells function, including all those cells that are inside that hard spherical casing that sits on top of your neck. If your brain cells aren’t getting the same level of oxygen, they may not function as well and more may even die. All of this could affect your cognitive function.
If your response is “rats” then you are right in more ways than one. The research paper also mentions a study of juvenile rats that tested what occurred when CO2 levels in the air that they breathed were raised. Levels of a neuroprotective growth factor went down, which in turn impaired brain development.
…
Nonetheless, this study does highlight the fact that our environment can readily affect our thinking ability. It is foolish to think that our abilities are somehow separate from our surroundings, that we can accomplish the same things under any condition.
If you believe that your environment doesn’t affect your thinking ability, try turning the heat way up in your room or wearing a Deadpool mask for long periods of time. See if you can still think and function at the same level.
