It is high time for human beings to take the ‘right’ action
towards saving the earth from major environmental issues. If ignored today,
these ill effects are sure to curb human existence in the near future.
Our planet earth has a natural environment, known as ‘Ecosystem’ which includes all humans, plant life, mountains, glaciers, atmosphere, rocks, galaxy, massive oceans, and seas. It also includes natural resources such as water, electric charge, fire, magnetism, air, and climate.
Engineering developments are resulting in resource depletion and environmental destruction. Modern technologies used in the engineering and manufacturing industry have a major impact on our life in the past few years. Due to the rapid changes in the engineering and manufacturing industry have been drastic changes in the environment.
The engineering and manufacturing industry has increased the use
of materials like metals, plastic, oil, and rubber. These are used in the
production of numerous end products which can be associated with different
industries such as Car production units, shipping industries, Cotton mills,
plastics industries, coal mining, heavy machinery, etc which are causing numerous
arduous effects and are considered to be non-environment friendly.
Crucial environmental issues are no more a blame game. While most of us crib about dirty air, smelly garbage, or polluted water, the least do we know it is “us” who is responsible for these unfavorable circumstances leading to cautionary environmental issues.
More
than half of the human population knows what pollution is, but we are still not
ready to face its damaging consequences. pollution is not only limited to water, soil,
and noise but has extended to light, visual, point, and non-point sources.
Human beings and their actions are majorly responsible for causing all types of
pollution.
Water pollution is
essentially caused by oil spills, urban runoff, and ocean dumping. Air
pollution arises from the burning
of fossil fuels, hydraulic fracturing, and gases emitted by vehicles. Water and
soil pollution are majorly caused by industrial waste.
Climate
change today is less of a natural process. It is rapidly occurring due to the
ill effects of human actions responsible for disturbing and harmful out comings
such as global warming, greenhouse effect, urban heat, coal industry, etc.
Climate change is not only
changing the overall weather scenario but
has larger and harmful effects. Some of these include the melting of Polar
Regions, the occurrence of new diseases, and permanent inhibition in the growth
of certain plants essential for human survival.
Global
warming is another environmental
issue which is an increase in the earth’s temperature due to the effect of
greenhouse gases called carbon dioxide, methane, water vapor, and other gases.
These gases possess heat trapping capacity that is needed to create a
greenhouse effect so that this planet remains warm for people to survive.
Without these gases, this planet would turn to be cold for life to exist.
During the past several decades, the accumulation of greenhouse gases has grown
rapidly, which means more heat gets trapped in the atmosphere and few of these
gases escapes back into space. These gases heat up the earth’s surface and this
results in global warming.
According to the NOAA, the average earth’s temperature has increased
by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century. Global
warming is a serious public health and environmental concern. Global warming
can have long-lasting effects which can result in the melting of glaciers,
climate change, droughts, diseases, and an increase in hurricanes frequency.
This is
a never-ending human tragedy that is responsible for causing all types of
environmental issues. Water pollution, resources crisis, gender imbalance,
pollution, land pollution, urban sprawling, deforestation, over production are
some common examples of dangerous effects cause by overpopulation.
Despite efforts taken by the government in terms of family
planning in many countries, overpopulation is difficult to control at the
international level. This has become more like a subjective concern and no
method seems to be 100% efficient to resolve the problem of overpopulation.
At
present, tons of garbage are produced by each household each year. Items that
can be recycled are sent to the local recycling unit while other items become a
part of the landfills or sent to third world countries. Due to an increase in
demand for food, shelter, and house, more goods are produced. This resulted in
the creation of more waste that needs to be disposed of.
Most waste is
buried underground in landfill sites. The presence of huge landfill sites
across the city poses serious environmental concerns. It affects human health,
degrades soil quality, affects wildlife,
causes air pollution, and results in climate change.
Acid
Rain simply means rain that is
acidic in nature due to the presence of certain pollutants in the atmosphere.
These pollutants come in the atmosphere due to the car or industrial processes.
Acid rain can occur in the form of rain, snow, fog, or dry material that settle
to earth. Acid rain may cause due to erupting volcanoes, rotting vegetation,
and sea sprays that produce sulfur dioxide and fires, bacterial decomposition,
and lightening generate nitrogen dioxide.
Acid rain can also be caused due to man-made sources which
include combustion of fossil fuels which release sulfur dioxide and nitrogen
oxides into the atmosphere. Acid rain can have devastating effects on aquatic
life, forests, public health and architecture, and buildings.
The
ozone layer is a layer of gas that sits 20-30 km above the arth’s surface.
It mainly contains contain ozone which is a naturally occurring molecule
containing three oxygen atoms. This layer is present in the stratosphere and
prevents too many harmful UV (ultraviolet) radiation from entering the earth.
The ozone layer is capable of absorbing 95-99% of the harmful ultraviolet radiation
that is emitted by the Sun.
However, during the last several decades, human and industrial
activity has contributed a lot
which has resulted in a considerable reduction in the ozone layer of the
atmosphere. The main cause of depletion of the ozone layer is determined as
excessive release of chlorine and bromine from man-made compounds such as
chlorofluorocarbons (CFCs).
CFCs (chlorofluorocarbons), halons, CH3CCl3 (Methyl chloroform),
CCl4 (Carbon tetrachloride), HCFCs (hydro-chlorofluorocarbons), (HBFCs)
hydrobromofluorocarbons and methyl bromide are some of the ozone-depleting
substances found to have a direct
impact on the depletion of the ozone layer.
Countries around the globe have been digging
into the earth’s crust in search of petroleum products that they can use or
sell to other countries to fulfill their thrust for energy. As you already
know, these energy sources are limited and exploitation of these sources beyond
a certain point will lead to an increase in air pollution and global warming.
Experts have already predicted these
non-renewable sources might vanish in less than 50 years from now but still, oil companies have been
using these sources of energy like they are going to be here for a
lifetime.
Habitat destruction occurs by pollution that causes habitats to
be destroyed because it changes the quality of air, water, and land while
becoming a breeding ground for toxins.
Habitat destruction can lead to the extinction of various species,
displacement of wildlife, disruption of underwater systems, change in the
composition, and quality of the soil among others. We must raise awareness and
teach others the importance of biodiversity to solve this serious environmental
issue.
Did you
know that only 2.5% of all the water in world is freshwater? And that only 1%
of accessible water is trapped in glaciers and snowfields. We only have real
access to 0.0007% of the planet’s water, that’s all we have to feed and fuel
over 6.8 billion people. And above all as per WHO, 1 in 3 people globally do not have access to clean drinking
or potable water. A water crisis is also known as water shortage, water
scarcity, and water stress.
Water crisis happens primarily due to water pollution, loss of
groundwater, climate change and can lead to a lack of sanitation, hygiene,
livestock and agricultural problems,
an increase in deaths, diseases, wars, and malnutrition.
