2. Introduction
• Pollution is a major concern for the environment and human health.
Pollution refers to the presence or introduction of harmful substances
(pollutants) into the environment that may cause harm to human health,
wildlife, and the ecosystem. There are many types of pollution that
affect our environment.
• Types of pollution; there are many types of pollution, the four basic
types that we will discuss are as following;
• 1 air pollution
• 2 water pollution
• 3 soil pollution
• 4 light pollution

3. Air pollution
• Air pollution is caused by the release of harmful chemicals and
gases into the air.
• The sources of air pollution can be natural, such as volcanic
eruptions, or man-made, such as combustion fossils and industrial
discharge.
• Air pollution can cause respiratory problems, decrease visibility,
and cause acid rain.

4. Water pollution
• Water pollution is caused by the introduction of contaminants such
as sewage, chemicals, and industrial waste products, into bodies
of water such as rivers, lakes, and oceans.
• The sources of water pollution can be domestic, industrial, or
agricultural.
• Water pollution can have severe impacts on marine life and human
health.

5. Soil pollution
• Soil pollution is caused by the introduction of chemicals and
substances such as pesticides, herbicides, fertilizers, and
industrial waste into the soil.
• Soil pollution can lead to decreased fertility, plant death, and
groundwater contamination.
• Soil pollution can also have a direct impact on animal and human
health.

6. Light collision
• Light pollution refers to excessive and unneeded artificial light
which has negative effects on humans, the environment, and
wildlife.
• Artificial light pollution can cause sleep deprivation, light
trespass, and glare.
• Light pollution can also disrupt ecosystems and interfere with
animal behaviors such as migration.

7. Conclusion
• Pollution is a complex and serious problem that requires collective
actions at all levels to address the causes and impacts of
pollution. We should do our part in reducing pollution by properly
disposing of waste, using renewable energy, supporting green
initiatives, and advocating for measures that improve air, water,
soil, noise, and light quality.
