1. Water pollution
2. Air pollution
3. soil pollution
4. Noise pollution
5. Light pollution

3. WATER POLLUTION
Water pollution is the contamination of water bodies, usually as a result of
human activities. Water bodies include for example lakes, rivers, oceans ,
and groundwater. Water pollution results when contaminants are introduced
into the natural environment. For example, releasing inadequately
treated wastewater into natural water bodies can lead to degradation of aquatic
ecosystems. In turn, this can lead to public health problems for people living
downstream. They may use the same polluted river water for drinking or
bathing or irrigation. Water pollution is the leading worldwide cause of death
and disease, e.g. due to water-borne diseases.

4. AIR POLLUTION
• Air pollution occurs when harmful or excessive quantities of
substances including gases, particles, and biological molecules are
introduced into Earth's atmosphere.It may cause diseases, allergies
and even death to humans; it may also cause harm to other living
organisms such as animals and food crops, and may damage
the natural or built environment. Both human activity and natural
processes can generate air pollution.

5. SOIL POLLUTION
• soil pollution as part of land degradation is caused by the
presence of human-made chemicals or other alteration in the
natural soil environment. It is typically caused by industrial activity,
agricultural chemicals, or improper disposal of waste. The most
common chemicals involved
are petroleum hydrocarbons, solvents, pesticides, lead, and
other heavy metals.

6. NOISE POLLUTION
• Noise pollution, also known as environmental noise or sound pollution,
is the propagation of noise with harmful impact on the activity of
human or animal life. The source of outdoor noise worldwide is mainly
caused by machines, transport (especially planes) and propagation
systems. Poor urban planning may give rise to noise pollution, side-by-
side industrial and residential buildings can result in noise pollution in
the residential areas.

7. LIGHT POLLUTION
• Light pollution, also known as photo pollution, is the presence of
artificial light in the night environment. It is caused by excessive,
misdirected or obtrusive uses of light, but even carefully used light
fundamentally alters natural conditions. As a major side-effect of
urbanization, it is blamed for compromising health, disrupting
ecosystems and spoiling environments.
