Wait..why this question?
We’re here to discuss climate change, not get targeted.
Yes. But as Elon Musk aptly puts it, “We’re running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere can handle before there is an environmental catastrophe.”
Yes you guessed it right, the topic for the day is CARBON DIOXIDE.
Why is it such a big deal? It’s just another gas and the plants absorb it anyways.
How is it causing havoc in the first place?
This is how it goes: The sun emits heat energy in the form of Ultraviolet rays and visible light. While the earth makes its own effort in keeping the atmosphere cool by emitting part of it as infra red rays, gases like carbon dioxide manage to trap some of the heat and make the atmosphere warm.
So it’s simple, the greater the amount of carbon dioxide in the atmosphere, the warmer the surface of the earth, because the plants can’t absorb all of it!
CO2 (emitted highest when compared to other heat absorbing greenhouse gases like methane and nitrous oxide) is added to the atmosphere in large quantities by human activities like burning of fossil fuels like coal, oil and natural gas, deforestation, and cement production for rapid urbanization.
It is a vicious cycle that will only come back to bite us if not controlled.
The figure below gives a depiction of the cyclic changes the whole process can cause:
It is important that every single individual plays a role in controlling this, because gases do not stay in one place after emission.
Humanity has suffocated the earth enough, it’s high time we try and let it breathe now.
