Lesson Content/Board Summary

Effects of Pollution

Air Pollution

Air pollution is the presence of harmful gases, dust, or smoke in the atmosphere, which can affect living organisms.
The following are major effects of air pollution:

Causes respiratory diseases like asthma and bronchitis.
Leads to global warming by increasing greenhouse gases.
Contributes to acid rain, damaging crops and buildings.
Reduces air quality, affecting human and animal health.

Water Pollution

Water pollution occurs when harmful substances contaminate rivers, lakes, or oceans.
These include:

Spreads waterborne diseases such as cholera and typhoid.
Harms aquatic life, reducing fish populations.
Contaminates drinking water, affecting human health.
Disrupts the ecosystem balance in rivers and lakes.

Soil Pollution

Soil pollution is the degradation of soil quality due to chemicals, waste, or other harmful materials.
They are:

Reduces soil fertility, affecting crop production.
Introduces toxins that may enter the food chain.
Causes land degradation and erosion.
Harms microorganisms essential for healthy soil.

Noise Pollution

Noise pollution is the excessive sound that can harm human and animal health.
Examples include:

Causes stress, hearing loss, and sleep disturbances.
Interferes with communication among humans and animals.
Reduces productivity due to distraction and fatigue.

Effects on Human Health

Pollution can have both immediate and long-term effects on personal health.
The following are effects on humans:

Increases risks of respiratory and cardiovascular diseases.
Causes skin infections and allergies.
Leads to mental stress and reduced quality of life.
Can result in chronic illnesses and premature death.
