Impact of Land Pollution
In today's modern world, man becomes a victim of pollution in
some form or the other, because man fails to decomposition those toxic
substances in some form or the other to fulfil his physical needs. Due to which
many types of pollution are generated in the environment, and this pollution
makes man suffering from many types of harm. One of them is the effect of soil
pollution which directly or indirectly affects humans / animals. The result of
which is seen negatively in flora, fauna and humans.
1. Disturbances in the food chain
The soil became fertile when we initially used fertilizers
and pesticides to increase the fertility of the soil. But today to meet the
food demand of the growing population, when farmers use fertilizers,
pesticides, herbicides, chemical drugs in large quantities for more production
of the crop, the soil starts getting polluted. The use of organic or inorganic
insecticides such as benzene, hexa chloride, DDT, etc. to protect the crop from
fungi, insects and insects etc., have a negative impact on the food chain. It
affects the food chain as a whole, with frequent use of fertilizers,
insecticides, herbicides, chemical drugs and fungicides negatively impacting
the soil food chain, causing direct or indirect negative effects on human health
and ultimately its result reaches the flora, the animals. and negatively
affecting humans, flora and fauna. All the animals and plants in the food chain
are completely interdependent in nature. If the chain itself becomes
unbalanced, then surely all the flora and fauna associated with the food chain
will also be completely affected. Soil pollution has a very negative impact on
the food chain. When the food chain is affected, many types of diseases do
develop on the flora and fauna associated with it, and many animals and birds
also die, due to the food chain being affected, negative changes also occur in
the flora and fauna. Negative changes in the DNA of flora and fauna are a sign
of great danger for nature.
2. Desertification of land
The most profound effect of desertification of land is the
loss of biodiversity and the loss of productivity potential, that is, the loss
of productivity. Due to the development of land, over-exploitation of trees and
the continuous decrease of biological productivity, the expansion of
desertification is increasing day by day, due to lack of rainfall and surface
drainage system in this area, the soil becomes covered, due to which Due to the
loss, desertification continues to increase. Due to the physical need of
humans, urbanization and the use of harmful fertilizers, insecticides,
fungicides in agriculture is increasing continuously. Due to which the
production capacity of the soil is gradually lost, eventually that land turns
into barren land, due to which desertification increases continuously. In
today's modern world, man has started exploiting trees in excessive amount to fulfil
his material needs, the result of which will be seen in the future that the
development of desertification in that area will happen automatically, in the
form of desert formation. But in the highland plateau of Madagascar, 10% of the
entire country has been transformed into desertification due to the farming
method of shifting agriculture, that is, cutting and burning . Nile Valley, due
to the salt logging and water logging, the yield of crops has decreased. this
Quantity of shortage has emerged as a major problem. Which is continuously
increasing the development of desertification of the land.
3. Loss of Biodiversity
Biodiversity is severely damaged by land pollution, when land
pollution includes too many pesticides, fungicides, toxic waste from industrial
areas, radioactivity from nuclear, toxic water from urbanization, when absorbed
into the soil, the soil The components of the structure and texture begin to
change. And the soil becomes more toxic than before. If a crop is grown in this
soil, it disturbs the food chain in the form of a toxic, and the toxic element
obtained from various sources in the soil is absorbed by the crop there.
Ultimately it gets toxic elements to humans, animals and plants, due to which
many types of diseases start to occur to humans. Mostly it is seen, when an
alien species starts encroaching on the indigenous species, then gradually the
encroachment of the foreign species increases greatly, due to which the habitat
of the indigenous species starts to be destroyed. It acts as a threat to
biodiversity. For example Congress grass, it has arisen as a huge problem in
India today. And this is a sign of a huge threat to biodiversity.
4. Loss of Soil Fertility
In today's modern world, the dependence on agriculture for
the food supply of the growing population is increasing day by day, due to
which, in order to increase the productivity of agricultural work, farmers use
more and more fertilizers, pesticides, fungicides such as inorganic
fertilizers. Drugs are used extensively. Due to which the pH scale of the soil
increases excessively, or becomes very low. As a result, the structure and
texture of the soil changes, and the soil becomes harder than before. And
gradually losing its natural properties, the soil remains uncultivable. Its
negative effect is on the lower yield than the higher yield of the crop, that
is, the soil accepts more acidic or alkaline than before. Due to which it is
not possible to do agricultural work in that soil.
5. Increase in Pollution of Water and Ground water
Ground water gets polluted naturally or unnaturally due to
soil pollution, due to increase in various sources of soil pollution such as
fertilizers, pesticides, radioactivity, sewage, mixture of metals, acidity and
alkaline properties. , then its effect also starts on the pollution of ground
water. When the soil becomes more saline or more alkaline, it slowly seeps to
the ground water, which increases the concentration of these salts in the
ground water, which also pollutes the ground water. Harmful chemicals and heavy
metals or products used in the production of raw materials from many
agricultural, nuclear, urbanization and industrialization processes are known
to cause land pollution. Due to soil pollution, the toxic chemicals present in
the soil, such as acidic sludge and alkaline, when it rains on the land or
water flows through rivers and streams reach these polluted soils, then such
toxic chemicals and toxic elements in the water. They get mixed, due to which
the water also gets polluted, and this polluted water gradually starts going
underground. Which gradually increases the concentration of these toxic
elements in the ground water, and eventually the ground water also gets
polluted.
6. Health damage due to soil pollution
Soil pollution definitely causes harm to health directly or
indirectly, soil pollution acts as a very harmful for health, because the toxic
element from soil pollution enters the body through the food chain, the toxins
present in the soil When the elements (a mixture of arsenic, mercury, fluoride,
radioactivity, toxins) are taken by the tree plants as their food, the
concentration of these toxic elements increases in these tree plants, and the
same tree plant when we eat it. If we take it in the form of food, then that
toxic element enters our body. And this gradually increases the concentration
of those toxic elements, and it becomes very dangerous for the health of humans
and animals. Polluted soil causes many damages to humans, for example diseases
such as cancer, leukaemia caused by contact with soil contaminated with
chemicals, such as gasoline, caused by benzene. The same kidney and liver
damage when caused by a mixture of chemicals such as mercury cause in the body
when in excess, damage to the nervous system especially the presence of lead in
the soil proves very harmful, and this is especially the case in children.
affects. Soil pollution can cause even more serious diseases.
7. Negative impact on flora and fauna
In the effect of soil pollution, mainly trees, plants and
animals are highly affected, when the soil becomes highly polluted, then the
plants around it are unable to survive, apart from this, if any tree plant is
produced in that polluted soil, then It is not edible, or other organisms
cannot make it edible, if any organism takes the plant grown in that polluted
soil as food, then we are definitely seriously ill. , and begins to have a deep
impact in the life cycle of that organism, as he becomes afflicted with
diseases, becomes disabled, or even attains death.
8. Poisonous animals also originated due to soil pollution
Poisonous animals also arise due to soil pollution. When the
soil becomes highly polluted, the structure and texture of the flora and fauna
around it starts changing, due to which the effect of that polluted soil starts
negatively on those fauna, and that animal also gets polluted. Due to the
radioactivity caused by atomic bombs in Nagasaki and Hiroshima, for example,
there is no growth of fauna and flora there, but whatever Fauna or flora has
evolved, it has accepted the difference in various properties in its internal
structure and texture, that is, even today there is a difference in the
structure and texture of animals and plants.
9. Damage to natural and artificial habitats due to soil
pollution
The natural and artificial habitat of all the terrestrial
flora and fauna that has developed in the earth is the soil, in the soil
itself, many animals and plants determine their habitat, but when this soil
becomes polluted naturally or artificially. then it is no longer habitable.
Rather it does harm to those flora or fauna, and it proves fatal. Therefore,
many vegetation gradually end up in the polluted soil, or gradually there is a
negative effect in the structure and texture of these vegetation. At the same
time, many animals start choosing other places instead of living in the
polluted soil, due to which no one lives in that polluted soil, that is, due to
soil pollution, natural and artificial habitats are heavily damaged and
damaged.
10. Effects of Soil Pollution in Climate Change
When man does not dispose of excessive amount of fertilizers,
chemical fertilizers, pesticides, industrialization, various kinds of toxic
substances are born, which proves to be harmful to human life, and these toxic
substances gradually spread to the surrounding vegetation. And the organisms
together in the food chain of the animals disturb the same completely. Due to
which the surrounding flora and fauna start getting affected and destroyed, or
they are forced to leave that area and go to some other area. When such events
occur, the surrounding climate begins to be affected, such as the death of trees
and plants, there seems to be a negative effect on the surrounding environment.
Due to which negative changes are also seen in the surrounding climate, due to
which the flora and fauna have to suffer. In those places, sometimes flood
situation arises, and sometimes severe drought suffers.
11. Economic loss due to soil pollution
When soil becomes polluted naturally or unnaturally, it is no
longer usable, when a large amount of metal and non-metallic elements or toxic
substances are mixed in a soil. soil does not remain suitable, neither
agricultural work can be done in that soil, nor can building construction,
industrial construction or other types of economic activities be done in that
soil. Because when that soil is toxic, its negative effects are seen in the
surrounding environment when soil pollution occurs, it acts as an economic
loss. The productivity of that soil is lost, and it becomes a matter of great
concern, because without soil the food chain cannot be completed. Which is
essential for the innumerable flora and fauna living on the earth. If the soil
in this earth becomes polluted, then it can have many harmful effects.
