Land Usage
Land use- is the human use of
land. Land use and land
management practices have a big
impact on natural resources such
as water, soil, nutrients, plants and
animals.

Land Pollution
 Plastic bottles/containers, cans,
and gas powered vehicles are
bad for the environment.
 Landfills are the worst for the
environment because they are
holes in the ground where the
waste is placed.

 Rangeland- land used to graze livestock and wildlife
 Forestland- land used for harvesting wood, wildlife, fish, nuts, and other resources
 Cropland- land used to grow plants for food and fiber
 Parks and Preserves- land used for recreation and scenic enjoyment and for
preserving native animal and plant communities and ecosystems
 Wetlands, mountains, deserts etc- land that is difficult to use for human purpose
 Urban land- land used for houses, businesses, industry and roads.
How Do We Use Our Land Today?
We use our land today for several things such as:
Farming, Mining, Recreation, Highways, Building Cities.
When land is being used for houses, industries, roads, and businesses
it is known as urban land.
Rural land is an area of few people and large open spaces of land.
When land is being used for graze livestock and wildlife, it is known
as range land. 1/30/2016

Con….
- We use land in three major ways; woods in forests, crops in farm, and mineral resources!
Weather people live in rural or urban cities, we all depend on resources that are being produced
in the rural areas.
-Resources being produced by natural and
artificial ecosystems is known as ecosystem
services.
-Ecosystem Services:
-aesthetic beauty - purification of water & air
-regulation of climate -prevention of flood/drought
-movement and cycling of nutrients
-maintenance of biodiversity -detox wastes
-decompose wastes 1/30/2016

What is land pollution?
 Land pollution is when left over wasted is thrown away and piles up
in land fills
 Trash is also being thrown away into rivers and into forests as well
 Sometimes the waste in burned for fuel or energy
 This is a problem because the products thrown away might have oils
or chemicals in them or on them.
 In a average day in the United States, people throw out up to 200,000
tons of edible food and 1 million bushels of litter out of their
automobiles.

Pollutant on soil surface
When any liquid pollutant is on or just below the ground surface for any period of time, one of
three things could happen to it, if it is not cleaned up first.
1- pollutant might be washed away by precipitation,
causing little or no harm to the ground on which it was found.
Pollutants will simply accumulate somewhere else)

Con…
2- the pollutant, if volatile, could evaporate, again causing little harm to the soil
(however, not a solution to the bigger pollution problem, as it might become a
source of air pollution).
3- pollutant could infiltrate through the unsaturated soil, in much the same way as
ground water.

The issue with land pollution
 The issue with land pollution is that chemicals for the waste is
getting into the ground
 When that happens the ground water gets contaminated
 The pollution then gets into the soil and eventually gets in to the
air.
 If waste gets in the water it will make it unsafe to use or drink,
and if consumed there could be possible health problems.
 When the air gets polluted it is also a bad issue because it can
turn into something called acid rain, acid rain is rain that is very
acidic due to pollutants in cloud water. 1/30/2016

Bioremediation
A treatment process that uses microorganisms (yeast, fungi, or bacteria) to break down, or
degrade, hazardous substances into less toxic or nontoxic substances (carbon dioxide and
water)

Solutions for Land Pollution
 Disposing waste correctly.
 We can separate household waste at home.
 Recycling, Re-use and Reduce.
 Organic waste can be recycled by composting.
 Do not litter.
 Use biodegradable items
 Organic Gardens can help lower the amount of waste
sent to landfills.
 Set up household systems to help separate their waste
products.
