What is pollution?
According to the oxford dictionary pollution is defined as “the presence in or introduction into the
environment of a substance or thing that has harmful or poisonous effects” Pollution is caused because of human activities or even due to some natural
phenomena’s. There has been an increase in the rate of pollution in recent years, which has caused harm not only to the environment but also on human health. Pollution
can be in many types, however the main types of pollution's are land pollution,
air pollution and water pollution.
Air Pollution
CAUSES OF AIR POLLUTION
The main cause of air
pollution is due to the dangerous emissions of gases like Nitrogen Oxide, Sulphur
Dioxide and other greenhouse gases, which are emitted from factories, motor vehicles or by
other human activities or even because some natural phenomena’s
Household
activities like using wood fires for cooking can add to the smoke in the air, use of
incense and air fresheners can also contribute to the pollution.
In order
to get rid off garbage they are burnt in open lands, thus this smoke adds to the
pollution because of no proper waste disposal method.
An increase
in the amount of CFCs (chlorofluorocarbons) which is emitted due to the use of
refrigerators, air conditioners etc also add to the air pollution.
EFFECTS OF AIR POLLUTION
- · An increase in air pollution alters the ozone layer in the atmosphere. The ozone layer helps protect the earth from dangerous gases. A decrease in the ozone layer could lead to diseases like skin cancer.
- · As air pollution increases humans could also face many respiratory problems.
- · Many humans could find it difficult to breathe in this polluted air thus have diseases like bronchitis.
SOLUTIONS TO CONTROL AIR POLLUTION
- · Vehicle owners should take care of their vehicles in order to reduce the smoke emitted from them.
- · Factory owners should take care of their factories so that they can reduce the amount of chemicals emitted in the air.
- · Instead of burning garbage other methods that are better for the environment should be introduced.
- · Reduction in the use of air fresheners, incense, air conditioners, burning of firewood for cooking etc. can also reduce air pollution.
Water pollution:
CAUSES OF WATER POLLUTION
The
main reason for water pollution is because of waste dumped into the sea, river,
lakes and other water bodies, directly or indirectly, by human activities like
using the sea side for domestic purposes like bathing, washing, etc. this is mainly done in rural areas of developing countries like India.
Water
pollution is also caused by factories dumping waste like dyes, etc in the seas
and other water bodies.
Oil
spills because of human activities, while transporting oil can also add to the water pollution.

EFFECTS OF WATER POLLUTION
v Water
pollution affects the flora and fauna in the sea.
v Fishes find
it difficult to live in this polluted water and eventually die many species of
fishes are on the verge of extinction because of water pollution.
v Water
pollution not only affects marine animals but humans also, as it can cause
diseases like jaundice. Consumption of this polluted water could also lead to other diseases.
v Fishes in
the polluted water have a small amount of mercury in them, when these fishes
are consumed by humans it could be dangerous.
SOLUTIONS TO CONTROL WATER POLLUTION
v Waste from
factories should not be dumped in the sea but instead special provisions should
be made to dumb waste.
v While transporting
oils humans should be careful in order to avoid oil spills.
v The
government should enforce laws that will lead to lesser waste dumped into the
sea.
Land pollution:
Land pollution is caused by dumping household waste and factory waste in
open lands
due to lack of proper waste disposal methods.
In order to increase the growth of
vegetables, farmers have begun using pesticides and fertilizers. Excessive use
of these fertilizers also reduces the quality of the land.
In order to meet the demands of raw
materials like coal, mining has been increased. Thus mining is also one of the causes
of land pollution.
Deforestation in order to build
buildings is also another reason for land pollution which is increasing lately
because of urbanization and industrialization.
EFFECTS OF LAND POLLUTION
v
Land pollution affects the climate, as there is less forest
cover this results in lesser amout of rainfall.
v
Many species who cannot adapt to these climatic changes may
find it difficult to live and eventually die.
v
Land is wasted, which can be used for better purposes like agriculture.
v
There is also a spread of epidemics like plague, malaria,
etc due to no proper disposal methods.
SOLUTIONS TO CONTROL LAND POLLUTION
Ø
We should plant more trees.
Ø
Increase in the use of biodegradables products.
Ø
Waste should be disposed of properly instead dumping them
on open land.
Ø
We should adopt methods like Reduce, Reuse, and Recycle.
CONCLUSION
Pollution has been
increasing continuously lately, due to increase in pollution, it has been
difficult for animals and us to live in this polluted environment, with the help of
these solutions we can try and reduce the percentage of pollution, as pollution could be really dangerous for the environment and us humans.
