Who destroyed the environment on which human live?
Who is "devouring" the ozone layer, the earth's
protective umbrella? Who caused the sun's ultraviolet
rays to kill all live things on land, and force the
human race to be extinct? These are all questions
that have to be pondered.
With the progress of time, life for human beings
has become more and more comfortable. More and more
people are sitting at home enjoying the fruits of
modern material civilization. When summer comes,
people sit at home with the cool air from the air
conditioner and eat the ice cream from the fridge
without feeling the arrival of summer. But while
some people are enjoying this, they have no idea
about about the chlorofluorocarbon from refrigerators
and air conditioners are accelerating the destruction
of ozone, the "umbrella" to protect human.
If the ozone layer is largely devoured, there will
unprecedented ozone depletion. This way, the ultraviolet
ray in sunshine can hurt human body skin and raise the
temperature of the whole earth, leading to the greenhouse
effect. The hole in the ozone layer not only damages
the environment of the living beings to be alive, but
also directly threatens human health.
Is the little freon in the fridge really harmful to
human bodies? In the first 50 years, no one mentioned
the problem. It was not until 1973 that Mario Molina,
a Mexican-American chemist, first warned that the
earth's ozone layer had been damaged. He was also the
first person to publish this theory in the world. When
he issued this warning, no one paid any attention to
his "fallacy", and it was over.
According to relevant data, the hole in the ozone layer
is related to refrigerators and air conditioners. Freon
is a refrigerant associated with the functions of refrigerators
to preserve the freshness of food and air conditioners to
blow out natural air and regulate the indoor temperature.
At room temperature, freon is a colorless gas or volatile
liquid with slight flavor, low toxicity and stable chemical
properties. But it can also become a gas and destroy the
overall structure of the ozone when it evaporates into the
ozone layer, which decreases the concentration of ozone and
creates a cavity. In addition, any material containing
fluorine will also cause the ozone depletion as it is
released into the atmosphere during production and use,
resulting in a hole in the ozone layer. Ozone-destroying
substances such as refrigerators, air conditioners, hairspray,
mousse and detergent, which are produced millions of tons
each year, are responsible for the damage in ozone layer.
A large amount of Freon is discharged from refrigerators and
air conditioning refrigerants and floats in the upper atmosphere.
Under the radiation of the sun's ultraviolet ray, the ozone
decreases day by day while it is decomposed and damages human
beings’ natural barrier. Not only that, it is also in an
inseparable relationship with human physical and mental health
and the imbalance of whole ecosystem imbalance.
