Land pollution is the degradation of the Earth's land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping, and indiscriminate disposal of urban wastes. It includes visible waste and litter as well as pollution of the soil itself.
Examples of Land Pollution
Soil pollution is mainly due to chemicals in herbicides (weed killers) and pesticides (poisons which kill insects and other invertebrate pests). Litter is waste material dumped in public places such as streets, parks, picnic areas, at bus stops and near shops.
The accumulation of waste threatens the health of people in residential areas. Waste decays, encourages household pests and turns urban areas into unsightly, dirty and unhealthy places to live in.
The following measures can be used to control land pollution:
* anti-litter campaigns can educate people against littering;
* organic waste can be dumped in places far from residential areas;
* inorganic materials such as metals, glass and plastic, but also paper, can be reclaimed and recycled.
The major increase in the concentration of population in cities, along with the internal combustion engine, led to the increased number of roads and all the infrastructure that goes with them.
As the demand for food has grown exponentially with the increase of the human population, there is an increase in field size and mechanization. The increase in field size makes it economically viable for the farmer but results in loss of person and shelter for wildlife, as hedgerows and copses disappear. When crops are harvested, the naked soil is left open to wind after it has been compacted by heavy machinery. Another consequence of more intensive agriculture is the move to monoculture. This is unnatural, will deplete the soil of nutrients, allows diseases and...
