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.

Oil field is a part of the environment pollution. The industries are developing. Also there are a lot of oil factories which are building. So soil containing hydrocarbons from leaking oil tanks. That makes the soild are impact thier qualities. These contaminants polluted the soils and produced some stinking smell. That makes the environment lost it's natural atmosphere and vividness.
On the other hand, The composting and pesticides are the reasons that influence the environment. Also they effect poeple's health because they belongs to one of the chemicals of the industry. In terms of chemicals, they are always a kind of harmful matters. Furthermore, poeple didn't treature the environment. They alway throuht garbages away. That makes the environment was very terrible. They would bring a lot of bugs and mosquitoes which would hurt poeple. Otherwise, the garbages were piled on the ground for a long time. It would decay, and produced chemical reaction. This reaction would discharge stinking smell and matters which were destroyed the soils. Thereby, people must notice these factors. And find out the suitable way to protect the environment and bring the healthy life to people.

Examples of Land Pollution
Soil PollutionSoil 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.
Waste DisposalThe 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.
Control Measures
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.
