Atmosphere without Us
Earth’s atmosphere is composed of the gases that surround the earth’s surface
and held towards the planet by gravity. The atmosphere consists of different
layers; troposphere, stratosphere, mesosphere, thermosphere, and exosphere,
respectively (Chang, Zhang, Wang, & Zhu, 2015). Have you ever asked
yourself of how the atmosphere would be with the extinction of human beings on
the planet? Well, that’s an answer we
can only give my first understanding the effects human beings and their
activities have on the atmosphere.
industrial revolution was a technology breakthrough for the human population
but was a great disadvantage to the world we are living in. Human activities
have negative effects on the atmosphere leading to its destruction and adverse
effect on climate and other natural phenomena. In the instance of extinction of
human beings, the atmosphere would thrive and the climate will be perfect for
supporting human life and balanced as Mother Nature intends it to be. At the
moment adverse climate changes that affect the weather, seasons is caused by
human activities. Without human beings on the planet, there will be no
production of greenhouse gases which cause the atmosphere to trap heat,
changing climate negatively. Carbon dioxide and methane are the primary gases
that contribute to the greenhouse effect (Clarke & Tomlin, n.d., p.
Widespread combustion of fossil fuels by humans contributes to the above
condition, meaning that if humans vanished, the atmosphere would flourish.
humans, the ozone layer, part of the atmosphere will be protected from
destruction. The layer protects the very same beings that destroy it from ultraviolet
rays emitted by the sun. The use of chlorofluorocarbons is attributed to the
effect. Ground level pollution is another way that human beings destroy the
atmosphere through emission of industrial gases into the atmosphere ozone
molecules created through combustion of fossil fuels affects living things like
animals and vegetation. With smoke and other industrial gases in the air,
acidic rain is formed, and the above destroys vegetation. If human beings
vanish, industries will not be functional, there will be no emission of
industrial gases, and the atmosphere will be free from toxic gases and
substances (Fabian & Dameris, 2014).
the above, it is clear that the atmosphere would thrive without us on the
planet. We have done so much damage to the atmosphere that it would take
decades to build it back to normal and in those years human activities such as
gas emissions should not be present. It gets hard trying to safeguard the
atmosphere as effects of human activities is intense. Environmental organizations
are trying all they can to create awareness of the atmosphere, but before the
campaigns bear any fruit, a lot has to be done. Affecting the atmosphere does
not only affect climate but also the biosphere and the hydrosphere.
main way what we have done to the atmosphere affects hydrosphere shown through
the effects of acidic rain. Emission of sulfur dioxide into the air and
nitrogen oxides lead to the formation of acidic rain that is later drained into
water systems. The acid rain contaminates clean water that will be unfit for
consumption by any living creature. Adverse effects on the atmosphere also have
an impact on the biosphere which includes all living things. In the same
scenario where human activities lead to acidic rain, animals and plants are
affected by the same. A good example is a change in the hydro ecology where we
see that due to the acidic rain, life in water bodies is compromised. Lakes in
North America, for example, have shown drastic reduction in marine life to
acidic rain (McElroy & Fogal, 2008). The acidic rain also
damages the soil that leads to poor or no vegetation leading to starvation and
death due to droughts. Acidic rain is also a major contributor to the
destruction of forests especially in Western Europe and the eastern USA.
Hydrosphere without Us
hydrosphere consists, the liquid water component on the earth’s surface. It is
approximated that it covers more than 70% of the earth’s surface. It consists
of rivers, lakes seas, oceans, streams, water vapor in the atmosphere, ground
water, water held by the soil and rocks. The hydrosphere is always in motion,
and it is constituted of saline and fresh water molecules.
beings have a great effect on the hydrosphere through their activities. Most of
the effects are negative and hazard to the bio-life in the water sources and a
source of pollution to the hydrosphere. We would all like to imagine how the
hydrosphere would be without the impact of human activities. If humans vanish
all of a sudden, the hydrosphere will thrive and be free from pollution and
over-exploitation. One of the major changes we shall see in the hydrosphere if
humans vanish from the face of the earth is low or no pollution at all. Human
beings are a major cause of water pollution through several ways. One of the
major ways is through industrial waste dumping into water bodies (Araya, 2005).
industries have their waste outlets into rivers and other water sources are
contaminating the same making it useless to any cause. Leaking sewerage systems
also add to the above problem, seeing harmful chemicals finding their ways into
rivers, lakes and other water bodies. Ion molecules from industrial waste are
not that easy to absorb, and they remain in the hydrosphere for quite a long
time. Without human beings, the above pollution will be eradicated, and the
hydrosphere will be cleaner than it has ever been before. Another way the
hydrosphere is polluted is through burying of waste into the ground, especially
chemical waste, which is absorbed by the water that sips through the ground and
finds its way to water bodies.
spills also cause pollution and will be eradicated if human beings vanish from
planet earth. Another impact is that the hydrosphere will not be overstretched.
Human population is growing rapidly leading to a lot of water consumption and
wastage. The amount of water readily available for human consumption is only a
fraction of the total hydrosphere. Human beings, however, waste a lot of water
which at times leads to drying up of water reservoirs and desertification
around such areas. Humans also tend to redirect the hydrosphere from its due
course, like rivers, to water their industries. The above plays a major role in
hydrosphere pollution, through unregulated exploitation. If humans vanish from
the face of the planet, am sure the hydrosphere will breathe (“Earth’s
Hydrosphere and Water Pollution,” n.d.).
of human beings on the hydrosphere also has an adverse effect on the biosphere.
Most life is dependent on the hydrosphere. The hydrological cycle is the
driving gear of life on the planet. Plants and other organism depend on water
for growth. Without the hydrosphere or with a contaminated hydrosphere, plants
will not have water that stimulates their growth and development. The above condition
leads to a low vegetation cover that affects both animals and humans, leading
to catastrophic events such as droughts. The hydrosphere plays a major role in
the purification of saline water to fresh water through the hydrological cycle.
In these way animals, people and certain plants can get fresh water to consume.
Destruction of the hydrosphere by human activities has also led to the death of
bio-life that exists in the hydrosphere. We have heard so many cases where
pollution has led to the death of marine animals such as fish (Judd &
Hovland, n.d., p. 330). It is thus clear that the extinction of human
beings and their activities would be beneficial to the hydrosphere and prevent
all the negative impacts associated with human activities.
Biosphere without Us
biosphere consists of all living organisms from the smallest organism to
largest. A microscopic organism such as bacteria is part of the biosphere.
Plants, animals and human beings are also part of the biosphere. The biosphere
at times can be explained as an ecosystem or a community of organism that
function as a single unit. The human beings are the most superior of the
biosphere and the most important as they can maintain the flow of energy
through the system. However, the above is not the case, and human beings
destroy the biosphere instead of helping it thrive.
would you imagine the biosphere without the impact of human beings? Well, I
know what you may be thinking, lots of plants, vegetations, animals of all
species. Yes, you are right. The biosphere suffers a lot from the impact of
human activities, and their eradication from the face of the earth might just
be the answer to improving it. From the begging of times and especially during
the industrial revolution, man has always been thinking of development. We have
seen cities sprouting from all corners of the earth. Uncontrolled development
is one of the worst enemies of the biosphere. When human beings want to set up
infrastructure such as buildings, they do so at the expense of the biosphere.
Trees are cut down, through deforestation without an effort of planting others
to replace those cut-down. With human eradication, deforestation will be a
thing of the past and trees, and other plants will grow peacefully without
human interference. The above will create a favorable climate and limit drastic
climatic changes that affect the biosphere (Briggs, n.d., p. 84).
and gathering is another activity that will be eradicated with humans.
Overhunting and especially poaching is rampant leading to the extinction of
certain species in the biosphere. The gap left affects the biosphere as all its
components are complementary. Activities such as overfishing have led to a low
population of bio-life in the hydrosphere. Human beings also alter the habitats
of other living things. Development is the culprit to the above alteration, and
it may lead to the extinction of species or habitat fragmentation. Without
human existence, such habitats will remain intact, and biosphere will take its
natural course towards the coexistence of all its ecosystems. Land resources,
forest resources, and even fishery or aquatic resources are all at the mercy of
human beings. The more the growth in the human population, the higher the rates
of its destruction compared to when the population is low or better, when human
beings are eradicated from the surface of the earth (Smil, 2011).
activities lead to degeneration of the ecosystems all which are summed up by
the biosphere. Once human beings are gone, there will be no deforestation and
forests will cover the face of the earth attracting more rain, more life, and a
greener planet compared to the concrete planet we are heading towards. A change
in the biosphere affects the hydrosphere as well. A good example is when their
id deforestation, the hydrological cycle is affected. Trees absorb and release
water into the atmosphere; the water is formed into rain which supports growth
and survival of other plants. With the reduction of trees, a reduction in the
hydrosphere is expected, and desertification is also an expected outcome. Trees
also absorb carbon dioxide emitted by humans and other animals, keeping the
atmosphere safe from excessive CO2 (Richardson et al., 2013, p. 160-172).
Deforestation leads to less forest cover, and the excessive C02 that is harmful
to the atmosphere will not be absorbed. At the end of it destroying the
biosphere leads to the destruction of the atmosphere and the hydrosphere as
the above spheres of the earth are affected negatively by human activities.
Eradication of human beings from the earth will thus have positive effects on
the spheres. It is sad that despite the superiority man has over living things,
and the earth in general, he has failed to control and conserve it. Human
beings are too focused on industrial development that they forget the very
ecosystem that supports their existence. It is best is we correct the harm we
are causing to our earth because if it perishes, we too perish as part of it.
Protect the earth, protect your life!
