1. When we talk about air or water pollution, the reactions garnered are stronger. This is
because we can see the effects caused by the pollutants and their extent very clearly. It is
normal human psychology to believe in what you see first-hand. Our land on the other hand
is living a nightmare too. We may not be able to see the effects with clarity, but land is being
polluted and abused constantly and we are unable to calculate the damages incurred. Land
Pollution has come to become one of the serious concerns that we collectively battle.
Land pollution, in other words, means degradation or destruction of earth’s surface and soil,
directly or indirectly as a result of human activities. Anthropogenic activities are conducted
citing development, and the same affects the land drastically, we witness land pollution; by
drastic we are referring to any activity that lessens the quality and/or productivity of the land
as an ideal place for agriculture, forestation, construction etc. The degradation of land that
could be used constructively in other words is land pollution.
Land Pollution has led to a series of issues that we have come to realize in recent times, after
decades of neglect. The increasing numbers of barren land plots and the decreasing numbers
of forest cover is at an alarming ratio. Moreover the extension of cities and towns due to
increasing population is leading to further exploitation of the land. Landfills and
reclamations are being planned and executed to meet the increased demand of lands. This
leads to further deterioration of land, and pollution caused by the land fill contents. Also due
to the lack of green cover, the land gets affected in several ways like soil erosion occurs
washing away the fertile portions of the land. Or even a landslide can be seen as an example.
Types of land pollution.
There are different types of land pollution. Many publications group them differently. Let us
see these four main types:
Solid Waste
These include all the various kinds of rubbish we make at home, school, hospitals, market
and work places. Things like paper, plastic containers, bottles, cans, food and even used cars
and broken electronic goods, broken furniture and hospital waste are all examples of solid
waste. Some of these are biodegradable (meaning they easily rot or decay into organic
matter). Examples include food droppings, paper products as well as vegetation (like grass
and twigs). Others are not biodegradable, and they include plastics, metals and aluminum
cans, broken computer and car parts.
Because these do not easily decay, they pile up in landfills (a place where all the city’s
rubbish are sent), where they stay for thousands of years. These bring great harm to the land
and people around it. See the complete lesson on WASTE here.
Pesticides and Fertilizers
Many farming activities engage in the application of fertilizers, pesticides and insecticides
for higher crop yield. This is good because we get more food, but can you think of what
happens to the chemicals that end up on the crops and soils? Sometimes, insects and small
2. animals are killed and bigger animals that eat tiny animals (as in food chains) are also
harmed. Finally, the chemicals may be washed down as it rains and over time, they end up in
the water table below (causes water pollution).
Chemicals
Chemical and nuclear power plants producewaste materials that have to be stored
somewhere. Fertilizer, insecticides, pesticides, pharmaceuticals manufacturers also produce
lots of solid and liquid waste. In many cases they are stored in an environmentally safe way,
but there are some that find their way into landfills and other less safe storage facilities.
Sometimes they also find their way into leaking pipes and gutters. They end up polluting
soils and making crops harmful to our health.
Deforestation
Humans depend on trees for many things including life. Trees absorb carbondioxide (a
green house gas) from the air and enrich the air with Oxygen, which is needed for life. Trees
provide wood for humans and a habitat to many land animals, insects and birds. Trees also,
help replenish soils and help retain nutrients being washed away. Unfortunately, we have cut
down millions of acres of tree for wood, construction, farming and mining purposes, and
never planted new trees back. This is a type of land pollution.
Causes ofLand Pollution
Below are the sources of land pollution:
1. Deforestation and soil erosion: Deforestation carried out to create dry lands is one of the
major concerns. Land that is once converted into a dry or barren land, can never be made
fertile again, whatever the magnitude of measures to redeem it are. Land conversion,
meaning the alteration or modification of the original properties of the land to make it use-
worthy for a specific purposeis another major cause. This hampers the land immensely. Also
there is a constant waste of land. Unused available land over the years turns barren; this land
then cannot be used. So in search of more land, potent land is hunted and its indigenous state
is compromised with.
2. Agricultural activities: With growing human population, demand for food has increased
considerably. Farmers often use highly toxic fertilizers and pesticides to get rid off insects,
fungi and bacteria from their crops. However with the overuse of these chemicals, they result
in contamination and poisoning of soil.
3. Mining activities: During extraction and mining activities, several land spaces are created
beneath the surface. We constant hear about land caving in; this is nothing but nature’s way
of filling the spaces left out after mining or extraction activity.
4. Overcrowded landfills: Each household produces tonnes of garbage each year. Garbage
like aluminium, plastic, paper, cloth, wood is collected and sent to the local recycling unit.
Items that cannot be recycled become a part of the landfills that hampers the beauty of the
city and cause land pollution.
3. 5. Industrialization: Due to increase in demand for food, shelter and house, more goods are
produced. This resulted in creation of more waste that needs to be disposed of. To meet the
demand of the growing population, more industries were developed which led to
deforestation. Research and development paved the way for modern fertilizers and chemicals
that were highly toxic and led to soil contamination.
6. Construction activities: Due to urbanization, large amount of construction activities are
taking place which has resulted in large waste articles like wood, metal, bricks, plastic that
can be seen by naked eyes outside any building or office which is under construction.
7. Nuclear waste: Nuclear plants can producehuge amount of energy through nuclear fission
and fusion. The left over radioactive material contains harmful and toxic chemicals that can
affect human health. They are dumped beneath the earth to avoid any casualty.
8. Sewage treatment: Large amount of solid waste is leftover once the sewage has been
treated. The leftover material is sent to landfill site which end up in polluting the
environment.
9. Atmospheric deposition: Air pollution doesn'tremain air pollution forever. Ideally it
disperses, so the concentration of problematic chemicals becomes so low that it no longer
constitutes pollution. Sometimes, though, it falls back to the ground and becomes either
water pollution or land pollution.
Effects of Land Pollution
1. Soil pollution: Soil pollution is another form of land pollution, where the upper layer of
the soil is damaged. This is caused by the overuse of chemical fertilizers, soil erosion caused
by running water and other pest controlmeasures.
2. Change in climate patterns: The effects of land pollution are very hazardous and can lead
to the loss of ecosystems. When land is polluted, it directly or indirectly affects the climate
patterns.
3. Environmental Impact: When deforestation is committed, the tree cover is compromised
on. This leads to a steep imbalance in the rain cycle. A disturbed rain cycle affects a lot of
factors.
4. Effect on human health: The land when contaminated with toxic chemicals and pesticides
lead to problem of skin cancer and human respiratory system. The toxic chemicals can reach
our bodythrough foods and vegetables that we eat as they are grown in polluted soil.
5. Cause Air pollution: Landfills across the city keep on growing due to increase in waste
and are later burned which leads to air pollution. They become home for rodents, mice etc
which in turn transmit diseases.
6. Distraction for Tourist: The city looses its attraction as tourist destination as landfills do
not look good when you move around the city. It leads to loss of revenue for the state
government.
4. 7. Effect on wildlife: The animal kingdom faces a serious threat with regards to loss of
habitat and natural environment. The constant human activity on land, is leaving it polluted;
forcing these species to move further away and adapt to new regions or die trying to adjust
8. EXTINCTION OF SPECIES • Species are pushed towards endangerment and extinction
primarily by two processes.Habitat fragmentation, Habitat destruction. Both the actions can
cause some species to go extinct and others to become invasive.
9. BIO MAGNIFICATION• Process in which certain non-biodegradable substances go on
accumulating in the food-chain. it puts all the species above and below it at risk, and
ultimately affects the food pyramid.
10. EFFECTS ON BIODIVERSITY• Species extinction and bio magnification is going to
overthrow the balance of nature very significantly. The main reason for this is disturbance
created in the food chain
Other issues that we face include increased temperature, unseasonal weather activity, acid
rains etc. The discharge of chemicals on land, makes it dangerous for the ecosystemtoo.
Solutions for Land Pollution
1. Make people aware about the conceptof Reduce, Recycle and Reuse.
2. Reducethe use of pesticides and fertilizers in agricultural activities.
3. Avoid buying packages items as they will lead to garbage and end up in landfill site.
4. Ensure that you do not litter on the ground and do properdisposalof garbage.
5. Buy biodegradable products.
6. Do Organic gardening and eat organic food that will be grown without the use of
pesticides.
7. Create dumping ground away from residential areas.
i. Encourage organic farming.
ii. Propergarbage disposal.
iii. Recycle garbage.
iv. Reduce use of herbicides and pesticides.
v. Avoid over packaged items.
vi. Efficient utilization of resources and reducing wastage.

Several creatures survive under the land too. Disrupting the harmony of the land, is
disrupting their habitat. This has led to several creatures reaching the endangered status like
the Gilbert's Potoroo in Australia.
We walk and survive on land. It is literally the base of our ecosystem. It is in our good
interest to take care of it and nurture it.
Some important facts on land pollution.
Here are a few facts about land pollution:
Facts on paperrecycling
A spokesman from a Wiltshire (UK) said the county recycled more than 700 tonnes of
plastic bottles and cardboard every month. BBC
Recycling a tonne of paper spares 17 trees, and Recycling half the worlds paper would
free 20 million acres of forest land.
Recycling paper uses 70% less energy than to manufacture paper from virgin materials.
Every 10 tonnes of paper recycled is 10 tonnes less on its way to landfill.
The UK uses almost 13 million tonnes of paper and cardboard each year.
Paper and cardboard can decomposefairly easily, but the process gives off methane (a
greenhouse gas), which contributes to climate change
6. Offices in the UK throw away around 1 million tonnes of paper each year. The bulk of it
ends up in the landfill.
Facts on metal recycling
Recycling 1 aluminium can saves enough energy to run a TV for 3 hours.
Once an aluminium can is recycled it is part of a new can within 6 weeks.
There is no limit to the amount of times an aluminium can can be recycled.
The energy it takes to make 1 new aluminium can is the same as it is to make 20 recycled
cans.
Over 4 billion aluminium drinks cans were sold in 1998, if they had been collected for
recycling they would have been worth £38 million.
Nearly 60% of the aluminium used in the U.K. has been previously recycled.
Recycling steel and tin cans saves 74% of the energy used to producethem.
General facts
Every year one American produces over 3285 pounds of hazardous waste.
Land pollution causes us to lose 24 billion tonnes of top soil every year.
Americans generate 30 billion foam cups, 220 million tires and 1.8 billion disposable
diapers every year.
We throw away enough trash every day to fill 63,000 garbage trucks.
Every day Americans throw away 1 million bushels of litter out their car window.
Over 80% of items in landfills can be recycled, but they’re not.
The main human contributor to pollution are landfills.
