What is Land
Land pollution is a build up of toxic
chemical compounds, radioactive materials or solid wastes. These solid
wastes include; garbage, paper, plastic and other synthetic materials,
metals and wood. Each year, billions of solid waste is thrown out.
Pesticides, spilled chemicals and acid rain all contribute to land
What causes land
Solid waste can be unwanted paper, plastics and other
synthetic materials, wood and metal that we don’t need any more. Some of these
things get incinerated, recycled or dumped in a land fill.
The best option for solid waste is recycling. Recycling means that we
can use materials again and again. Items are often melted down and
shaped again. If solid waste is not recylced it generally ends up
rotting in a land fill. Land fill isn't a great option for our waste
because the rubbish just sits there and more and more
rubbish is piled on top of it until the hole in the ground is
full. Once the hole is full it is covered up and another piece of
land is found for the rubbish. Disposing of rubbish this way needs
plenty of spare land, which many countries and towns don't have and it
is also bad for the environment because whatever is in the dumped
rubbish breaks down and embeds itself into the earth. When
using landfill dumps, all of the rubbish that is either dumped or buried rots
and produces methane gas which can seriously harm the Ozone layer.
Incinerating is another way to
dispose or solid waste, it is still bad but not as bad as a land fill.
When items are incinerated, the rubbish pretty well burns away to
nothing but toxic chemicals can be given off in the
process creating air pollution.
Farmers spraying pesticides to
product their crops pollute the land and soil. Pesticides when sprayed,
depending on the weather and the quantity that is sprayed, sink
into the soil and into the water table. If rain occurs pesticides can
also run off into creeks and rivers. Pesticides seep through the soil
and into the water table. The water table is where plants with big long
roots get most of there water from, people in houses or businesses
who have spear pumps get there bore water from the water
Spraying pesticides to protect plants therefore has a secondary negative affect. It can actually
cause poisoning of plants, animals and people.
A variety of other pollutants can also seep into the soil including oil, petroleum,
How does land pollution affect us?
We now know that pollution can kill or sicken plants, animals and
people. Pollutions can also change the environment. If all wastes are
not disposed of properly, the damage they can do to the land is very
high. The land is often polluted without us even knowing. If the
land is polluted with chemicals when it rains the posioned soil can
travelling to different areas poisioning other places on the way.
The plutted soil can also get into the waterways killing the
creatures living in creekes and rivers.
