Answer Details
(a) What is an environmental hazard?
An environmental hazard is any natural or human-induced event or condition in the environment that poses a threat or danger to human life, property and other living things. It is a situation with the potential to cause damage, injury, loss or destruction.
(b) Five examples of environmental hazards
- Flooding.
- Drought and desertification.
- Earthquakes.
- Volcanic eruptions.
- Soil erosion (also acceptable: landslides, storms/hurricanes, oil spillage, deforestation, pollution).
(c) Three effects of environmental pollution
- Health problems: polluted air and water cause diseases such as cholera, respiratory illness and skin infections, and can lead to death.
- Destruction of ecosystems and living things: pollution kills fish, wildlife and plants, poisons the soil and reduces biodiversity.
- Damage to agriculture and economic loss: contaminated soil and water lower crop yields and fish catch, spoil water supplies and impose high clean-up and treatment costs; air pollution also contributes to global warming and acid rain.
