Human activities have a great impact on the planet earth.
Although the advanced technologies that we utilize
benefit us, it has a long-lasting effect on the earth.
According to the recent surveys, due to
continuous hunting, poaching, and deforestation,
a large number of species are endangered and
extinct and some novelists also believe that
this biotic crisis will remain for five million
years and will diminish the food chains.
Similarly, after the industrial revolution phase, the land
and the atmosphere of the earth has entirely changed.
According to the recent surveys, there held a lot of conversation
about the planet Nibiru to strike the Earth in September 2017.
Though the information did not come to be true, the
people are still scared due to its presence and facts.
The presence of Carbon dioxide in the atmosphere has enhanced to 30
percentage which causes global warming and degradation of the planet.
Some known risks caused by the humans that have
probably more chances to affect the planet include:
The misuse of nanotechnology:
The nanotechnology is termed as “gray goo” by Eric Drexler (nanotechnology pioneer).
This technology involves the “self-replicating robots” that possess
the capability to replicate and divide them and form another robot.
These robots are very hazardous as they require enough consumption for the
replication process and that’s why they consume the biomass of earth.
More the number of robots are less the biomass will remain on the earth.
Climate change:
The modification in the weather for a long period of time
due to human activities is termed as climate changes.
It is especially caused by the global warming.
Nuclear holocaust:
A nuclear holocaust is caused by the nuclear wars between different countries.
According to the famous scientists, a thermonuclear war can end the modern
technologies in the earth and hence diminish the modern civilization.
Genetically engineered disease:
It is often known as genetic modification and is a great
method used for producing the crops in the agricultural field.
However, the fact that whether the food generated through
this process is safe to consume is not clarified.
It also affects other microbes and hence creates a scenario of “end of the earth”.
Resource depletion:
Resource depletion refers to decrease in the resources
due to its continuous utilization by the human.
Generally, the resources are classified as
renewable resources and nonrenewable resources.
The overuse of both the resources beyond the limit can cause resource depletion.
If the resources continuously decrease then the proceeding
generation would lack resource and hence earth will come to an end.
Disaster caused by physical and scientific experiment
Apart from the degradation of the earth caused
by the human, there are certain random events
that have the possibility to occur in the near
future and destroy the earth and its inhabitants.
Some of the major threats are a doomsday threat,
asteroid impact, virulent diseases, and much more.
Some major ways which can cause the earth to die are:
1. The extinction of humanity
2. The boiling of earth’s ocean
3. Reduction to a barren rock
4. Asteroid and meteoroids collision with earth
Let’s discuss some common threats which can end the life
of several species including the human in planet Earth.
Deadly asteroid impact
There are thousands of asteroids that closely
pass through the earth in every year.
Although these asteroids travel in their own path without hitting and striking our
planet, sometimes their way can be diverted and these asteroids may hit the earth.
Many small accidents of the same have happened in the previous years and
one such accident was that of a massive meteorite which hit the earth
and killed all the dinosaurs of our planet which
lead to the extinction of the species from earth.
Similarly, one asteroid blasted in 2013 in the regions
of Siberia leading to the death 1,500 people.
If the huge accident of an asteroid explosion takes place in the near future
on earth then it can ruin various species and destroy the human life.
Nuclear war
Nuclear war is one of the most dangerous and critical situations
which leads to the death of several people and natural environment.
One such war took place between the United States and Japan in which
the US dropped various nuclear bombs on Hiroshima and Nagasaki.
It killed thousands of people and damaged a lot of Japan’s property and businesses.
After this war, there is another threat of a World
War 3 between the United States and South Korea.
The US and Korea have most powerful weapons including the Russian Tsar Bomba.
If a country releases the weapons and nuclear missiles then it can kill
and injure around 90 percent of the people living in the particular area.
It may also affect the environment and other species
due to extreme radiations generated through the blast.
Methane bursts from the seabed
Though the methane explosion has rare chances to occur, it has
the capability to destroy the entire planet within few days.
One such methane explosion took place several
years ago and made the green earth a desert.
According to the scientists, this explosion was mainly caused because of the
greenhouse effect due to less production and slow production of methane.
The earth took 10 million years to overcome the deterioration caused by the explosion.
If the methane bursts again in the future then it will increase the
temperature of our planet from 15 degree Celsius to 30 degree Celsius
which will cause the icecaps in the Himalayan regions
to melt and bring flood in most cities of the country.
This will decay our earth and the survival on the same will become almost impossible.
According to the recent estimations, due to the melting of
permafrost can cause severe methane explosion in Siberia.
Ravaging solar storms
A major factor which can cause the end of the earth is the
dangerous radiations released by the sun in the earth.
A scientist has found that there is a small hole in the ozone layer.
The ozone layer is responsible to protect our environment
from the harmful and direct radiation coming from the sun.
However, due to the hole in the same, the harmful
radiation of sun reached the earth directly
causing the dangerous diseases among people
like skin cancer, tuberculosis, and much more.
If this hole increases continuously then it can damage and ruin
the earth killing thousands of people and diverse species.
The major reason behind the hole in the ozone layer is the use of
chlorofluorocarbons and other chemicals often used in perfumes.
The sun also releases the eruptions in the earth which
is again an alarming sign of a critical accident.
According to the scientific reports, mars become an arid planet
because of the harmful radiations produced by the sun onto the mars.
Similarly, if these rays continuously fall in the earth then
we can experience a red and an arid earth with no resources.
The creation of black hole by the scientists
The scientists were always trying to produce a machine
which breaks the proton into small substance.
The same was accomplished when the Large Hadron Collider was produced.
This machine has the ability to collide
thousands of protons together at a steady rate.
However, this machine has a very bad impact on the
earth and is often believed to deteriorate the planet.
Super-volcanoes eruption
The super-volcanoes eruption causes the major
devastation in the earth by producing a lot of dust
in the atmosphere which further obstructs the
radiation generated by the sun into the earth.
The recent reports state that there is similar volcano blast in Italy and the
scientist are engaged in observing whether this damage can block the sun?
This eruption can produce Sulphur dioxide and effect several nearby
regions including Italy, Eastern Europe, Mediterranean Europe, and etc.
Europe had also suffered from a volcano eruption 39000 years ago
and the country was destroyed when Campanian Ignimbrite blasted
and spread all over the regions covering a distance of about 2000 kilometers.
This disaster does not kill the people directly but leads to
the shortage of food, water, and other important resources.
It also leads to drought and the ultimate death
of the planet and several human and animals.
There are more chances of the earth to die in the following cases:
If an object bigger than the size of earth
hits or collides with the same at a fast rate
If an object passes through the earth and scoop it out of the whole
galaxy and the solar system leading its destruction and damage
Though these facts are very likely to occur in the
future, we can protect the earth in several ways.
One of the most important ways to do so is by eliminating the unnecessary usage
of renewable and nonrenewable resources and saving it for the next generation.
Also, if the people reduce the usage of harmful chemicals like
chlorofluorocarbons, substances producing carbon dioxide, carbon monoxide,
and much more then we can defend our earth from pollution and diseases.
