The document discusses different types of pollution including land, water, air, light, and thermal pollution. Land pollution is caused by improper waste disposal and agricultural practices. Water pollution contaminates water bodies and causes widespread illness, deaths, and ecosystem damage. Air pollution introduces harmful substances into the atmosphere. Light pollution causes unwanted artificial light at night that interferes with ecosystems and astronomy. Thermal pollution alters water temperatures from industrial processes like power plants.

1. THE POLLUTION

2. The pollution in the enviroment
The pollution is an international journal that seeks to publish papers that report
results from original, novel research that addresses significant environmental
pollution issues and problems and contribute new knowledge to science.
The pollution present in some place:

In the land

In the water

In the air

In the light

In the thermal

3. Land pollution
Is the degradation of earth's land surfaces often caused by human activities and
its misuse. Haphazard disposal of urban and industrial wastes, exploitation of
minerals, and improper use of soil by inadequate agricultural practices are a few
of the contributing factors.

4. Water pollution
Is the contamination of natural water bodies by chemical, physical, radioactive
or pathogenic microbial substances. Adverse alteration of water quality presently
produces large scale illness and deaths, accounting for approximately 50 million
deaths per year worldwide, most of these deaths occurring in Africa and Asia. In
China, for example, about 75 percent of the population (or 1.1 billion people)
are without access to unpolluted drinking water, according to China's own
standards. Widespread consequences of water pollution upon ecosystems include
species mortality, biodiversity reduction and loss of ecosystem services.

5. Air pollution
Is the introduction of chemicals, particulate matter, or microscopic organisms
into the atmosphere; in particular, when concentrations of those substances
cause adverse metabolic change to humans or other species. The most common
and widespread air pollutants include carbon monoxide, sulfur dioxide, nitrogen
oxides and particulate matter.

6. Light pollution
Is the intrusion of unwanted or unneeded artificial light into a man-made or
natural environment. A variety of somewhat separate phenomena comprise the
overall issue of pollution due to excess artificial light: Overillumination, glare, light trespass and skyglow. Adverse impacts of light pollution
include human annoyance, interference with ecosystems, human health
effects, interference with astronomical observation and wasteful consumption of
energy.

7. Thermal pollution
Is the act of altering the temperature of a natural water body, which may be a
river, lake or ocean environment. This condition chiefly arises from the waste
heat generated by an industrial process such as certain power generation plants.
