Environmental Issues: That Could Be Fatal
Environmental issues
are the result of the harmful effects of human activity on the bio-environment.
Water shortage, climate change, and loss of biodiversity are some major environmental
issues, but that’s not all. These problems should be solved if the world is to
maintain a supportive habitat for humans and other species. Here are some of
the environmental issues that are growing very fast at this time.
1. Overpopulation : Human overpopulation is a major environmental issue. Human
overpopulation is the condition in which the number of people living in any
country increases compared to the resources available there. Overpopulation can
result in an increase in births in any country, a drop in mortality, an
increase in immigration, and a lack of resources. It has also been proved by
scientists that the largest impact of humans on the environment is
overpopulation, overconsumption, and increasing population. According to the study
done on 30 October 2020, the world population at this time is 7.827 billion.
2. Water pollution: Water pollution is a growing crisis for the world, from large pieces of
garbage to invisible chemicals and dead bodies, polluting the world’s lakes,
rivers, ravines, groundwater, and ultimately the oceans.
Water pollution is
not only a threat to drought, inefficiency but also sources of fresh water,
drinking water, and other essential needs. Research has revealed that a
pollutant is common, especially in our tap water, called PFAS (poly and
perfluoroalkyl substances).
Most PFASs are used
to protect everyday objects from moisture, heat, and stains; Some of these
chemicals are also known for their long half-lives and are also known as
chemicals that are available forever. Protecting the water supply is very
important because even though about 70 percent of the world is covered by
water, only 2.5 percent of this 70 percent water is fresh. Out of this 2
percent water, only one percent freshwater is possible to reach, out of which
most of the water source is in the remote glaciers and ice plains.
3. Natural Disasters: A natural disaster is an inimical event that
occurs due to natural processes of the earth like tornadoes, hurricanes,
floods, volcanic eruptions, earthquakes, tsunamis, and all geological
processes. Natural calamity severely affects life, property, and the current
economic situation of the country. The severity of a natural disaster depends
on the resilience of the affected population of that country and also the
infrastructure available in the country.
An adverse event
does not rise to the level of a disaster if the population of that place is
small. The consequences of earthquakes are devastating and can also cause
permanent damage, which can take years to recover.
4. Air pollution and change of climate: Air pollution and Changes in climate
are the biggest environmental issues. The problem occurs due to an excess of
carbon in the atmosphere and seawater.
Carbon dioxide in the atmosphere is re-emitted and absorbs infrared wavelength
radiation. The amount of carbon in the air is increasing very rapidly day by
day. Two hundred years ago, the amount of carbon was 280 ppm (parts per
million), which has now increased to 400 ppm (parts per million), and the main
reason is the burning of fossil fuels, deforestation, and industrial
activities. Burning of coal, gas, oils, and wood is the main reason for the
excess of carbon, and this causes air pollution.
In a study
conducted by the WHO (World Health Organization), it has been proved that one
in nine deaths daily are caused by pollution. By replacing fossil fuels with
renewable energy, reducing emissions, and changing the industrial process in a
country, the government can reduce air pollution.
5. Deforestation: As with other environmental issues, deforestation is also a major
environmental issue. Species-rich forests are increasingly being destroyed to
make way for animal husbandry, soybean or palm oil plantations, or other
agricultural monocultures. The harvesting of forests is proving to be fatal for
the environment, such as the increase of carbon dioxide in the atmosphere, lack
of sufficient rainfall for irrigation of fields.
Today, about
30 percent of the Earth’s land is covered by forests. About 18 million acres of
forest are being destroyed each year, most of which are from tropical areas.
Tropical forests used to cover about 15 percent of the Earth’s land, which is
now reduced to 6 or 7 percent.
