The year 2020 always seems a curse to us.
It is right that this year has proven to be very difficult for humanity but
that doesn’t mean that all these problems came all of a sudden
But the fact is that even we know we have a big part in it
from natural destruction to rapid climate change we are more responsible than the nature itself
There is a video we made a few days ago concerning the biggest rainforest of the world Amazon
If you haven’t seen it make sure to check out
In that video we had discussed how the last wildfire that devastated this forest last year is a kind of our doing
because deforestation, one of the cruelest work of humanity has been
increasing the temperature continuously
You can clearly understand it by comparing the temperature of last few decades
Our nonsense works are destroying the earth and the biggest proof of it is global warming
in this video we will try to find out the things about this crucial problem and what are the impacts of it
Now terminologically global warming means the rise of world temperature but it doesn’t end there
Now the people who know a little about this event must know about greenhouse gas
Now the first thing that we think about greenhouse gas is that it is an absolutely harmful gas
Well it is partly right partly wrong
The first thing is earth would freeze to death if it wasn’t for this gas. In a way this gas helps us to stay alive
if there was not any greenhouse gas our earth would turn to a rocky dead planet like mars
now CFC is generally called a greenhouse gas
greenhouse gas helps us to warm our planet by storing enough sunlight so that life could sustain
but then why we call it harmful
 
It is because with our everyday life we are actually increasing the amount of this gas
from factory work to deforestation everything is increasing it
now you may ask that if this gas keeps us warm then why it is dangerous if  it increases in the amount
For that first we have to understand how our earth and its atmosphere react with sunlight
Now there is an important layer under our Stratosphere called Ozone layer
Generally when ultraviolet ray crosses the atmosphere
It reacts with oxygen and divides its atoms which then interacts with another oxygen molecule and
creates Ozone (O+O=O3)
of course this layer is filled with O3 and it plays an important role in repelling ultraviolet rays
Now as we discussed how we are helping greenhouse gases like CFC to increase
CFC contains Chlorine, Florin and Carbon from which Chlorine gets separated by sun rays before it reacts with
ozone and in the process it destroys the Ozone layer which we call Ozone Depletion
As Ozone layer weakens ultraviolet ray enters earth directly causing unnatural events
But the most harmful thing happens when sunrays can not escape our planet in a natural way
Actually sunlight returns to the space after hitting earth
But because today we have four times of extra greenhouse gas it traps the sunlight
that's supposed to go back
If we check the graph of temperature rise from Industrial revolution it gets clear for us
According to a study from 1906 to 2005 temperature rises between 0.6 to 0.9 degrees
Today every scientist is worried about this fact
It is so complicated that once scientists thought that global warming was a hoax but today we know
the reality
From ice melt down in polar regions to the rapid climate change everythings points towards this disaster
Even Amphan cyclone that took place in 2020 in India is marked by geologists to be a result of global warming
Scientists have recognized Sundarvans, the biggest delta of the world to be a potential spot that can be
indulged in water due to the rapid rise of water reserve
Icy countries like Alaska has already faced such disasters many times

in Netflix
Eventually the thing is that we as human beings are not conscious no matter what. We still harm our nature
in one way or another
And the funny thing is that most of us don’t pay heed to it
Neither we get teaching about it in our childhood nor we try to know about it ourselves
Until we don’t realize that it is our duty to keep our planet safe we will continue our selfish works
And when we face disastrous events we don’t even understand whom we should blame
