2. INTRODUCTION
Land pollution is the destruction of the
earth's land surfaces, often directly or
indirectly as a result of man's activities and
their misuse of land resources.

3. It occurs when waste is not disposed of
properly, or can occur when humans throw
chemicals onto the soil in the form of pesticides,
insecticides and fertilizers during agricultural
practices. Exploitation of minerals (mining
activities).
Since the Industrial Revolution, natural habitats
have been destroyed, and environments have
been polluted, causing diseases in both humans
and many other species of animals.

4. EXAMPLE OF LAND POLLUTION

5. CAUSES OF LAND POLLUTION
Agricultural activities: 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.
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.

6. 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.
Waste Produce: Humans produce vast
quantities of waste—in factories and
offices, in our homes and schools, and in
such unlikely places as hospitals. Even the
most sophisticated waste processing
plants.

7. EFFECTS OF LAND POLLUTION
• 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 control measure.
• 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.
• 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.

8. Cont..
• Effect on wildlife: The animal kingdom has suffered
mostly in the past decades. They face 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.
• 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
body through foods and vegetables that we eat as
they are grown in polluted soil.

11. COUNTRIES AFFECTED
• Linfen, China
• Haina, Dominican Republic
• Ranipet, India,
• Kabwe, Zambia

12. CONCLUSION
• Ideally, we don't just need to stop polluting land:
we also need to clean up the many contaminated
sites that already exist. Many former nuclear sites
have already been cleaned up as much as
possible. We need to educate and create
awareness of the dangers.
• All these things offer hope for a better future—a
future where we value the environment more,
damage the land less—and realize, finally, that
Earth itself is a limited and precious resource.
