- Engineering: Providing solutions to environmental problems like water treatment, waste management, and infrastructure development.
- Law: Creating environmental regulations and legal structures to protect natural resources.
- Political Science: Examining environmental issues, including government roles in addressing environmental challenges.
Environment Pollution
- Types: Air, Water, Soil, Noise, Plastic, Thermal.
- Air Pollution: Caused by industrial activities, vehicles, and release of Nitrogen/Sulfur oxides and particulate matter, harmful to human health/environment.
- Water Pollution: Results from industrial discharges, agricultural runoff, improper waste disposal, and oil spills, which impact ecosystems and human health.
- Soil Pollution: Arises from chemicals, heavy metals, and waste. Major sources are deposition of hazardous chemicals and waste.
- Noise Pollution: Unwanted sound from industrial activities, transportation, and urban development.
- Plastic Pollution: Caused by improper plastic waste disposal in rivers and various environments.
- Thermal Pollution: Discharge of heated water or air into natural water bodies/atmosphere disrupting natural temperature balance.
- Nuclear Hazards: Risks and dangers associated with the use, production, and disposal of nuclear materials and technology, impacting human health, environment, and wildlife.
Effects of Environmental Pollution on Mankind
- Climate Change: Pollution, particularly greenhouse gas emissions, affects human health and livelihoods.
- Respiratory Problems: Air pollution leads to respiratory issues like asthma and lung infections.
- Psychological Effects: Living in polluted environments contributes to stress, depression and other health issues.
- Cardiovascular Diseases: Exposure to air pollution increases risk of cardiovascular problems like heart attacks, strokes and hypertension.
- Developmental Impacts: Exposure to pollutants during pregnancy and early childhood can lead to birth defects, low birth weight, and developmental delays.
- Waterborne diseases: Polluted water can cause diseases like cholera, typhoid, and malaria.
- Reproductive health issues: Environmental pollutants can disrupt hormone function and affect reproductive health, leading to miscarriages, birth defects, and developmental abnormalities.
Causes of Environmental Pollution
- Industrial activities: Factories, power plants and manufacturing facilities release pollutants (chemicals, heavy metals, etc.) into the air, water, and soil.
- Transportation: Vehicles burning fossil fuels emit pollutants (carbon monoxide, nitrogen oxides) contributing to air pollution.
- Waste disposal: Improper waste disposal (plastics, electronics, hazardous materials) pollute land and water bodies.
- Deforestation: Clearing forests affects ecosystems releasing carbon dioxide, contributing to climate change.
- Population growth: Increasing population puts pressure on natural resources, causing pollution.
- Construction: Construction projects can cause soil erosion, sedimentation, and air pollution.
- Energy Production: Burning fossil fuels for electricity generation and heating releases greenhouse gases and air pollutants.
- Urbanization: Rapid urbanization increases demand for resources, leading to land conversion, pollution from vehicles, industries, and waste generation.
Controlling Air Pollution

- Impact on wildlife: Disrupting wildlife behavior and impairing their ability to locate food and mates.
Thermal Pollution
- Degradation of water quality by discharging heated water or air into natural water bodies or atmosphere,.
- This disrupts the natural temperature balance causing harmful effects on ecosystems and human health.
Causes of Thermal Pollution
- Industrial activities: Industries using water for cooling release heated water.
- Power generation: Power plants use water for cooling equipment.
- Waste heat from transportation: Heat generated from cars, trains, and planes can be indirectly transferred to water sources.
Effects of Thermal Pollution
- Fish mortality: Species requiring cooler water temperatures face stress or death.

Causes of Nuclear Hazards
- Radiation exposure -lonizing radiation: Alpha, beta, gamma rays causing DNA damage, cancers, radiation sickness and other health issues.
- Acute radiation sickness
- High doses over short periods causing vomiting, fatigue and even death.
- Long-term exposure (cancer, blood clotting, or heart attack).
- Nuclear accidents: Accidents at nuclear power plants or facilities causing radioactive material release into environment.
- Chernobyl accident (1986): A catastrophic nuclear accident release radioactive particles.
