Singapore treats contaminated water through advanced water purification techniques. It disposes waste through incineration and adopting the 3R approach of reduce, reuse, recycle. To reduce air pollution, Singapore enforces strict emission standards for vehicles and industries, uses cleaner fuels, and promotes the use of public transport.

1. Air Pollution Contaminants released into the atmosphere causing harm to the environment and organisms. Factories Automobile
Effects of Air Pollution • Causes respiratory problems. • Causes acid rain when pollutants dissolve in the rain. • *Release of chlorofluorocarbons(CFCs) causes global warming.
2. Land Pollution Pollutants or wastes are disposed on land causing harm to the environment and the organisms. Burning of trees Improper Disposal Improper Disposal of rubbish of toxic waste
Effects of Land Pollution • Land unsuitable for use. • Soil unsuitable for farming and breeding. • Toxic wastes may seep into water bodies causing water pollution.
3. Water Pollution Contaminants are released into water bodies causing harm to the environment and organisms. Water bodies: Oceans, Rivers and Drains Untreated sewage Pesticides Improper disposal of rubbish Oil Spillage
Effects of Water Pollution • Harms coastal wildlife (e.g. birds covered with oil) • Harms or kills marine life. • Causes stagnant water which encourages breeding of mosquitoes.
Man’s impact on the environment
1. List 2 positive impact of Science and Technology. (i) Medical advancement/New machinery (ii) Farming and breeding/Man-made materials 2. What are two sources of air pollution? Factories and automobiles. 3. State two effects of land pollution. (i) Land unsuitable for use/Toxic waste may seep into the water bodies causing water pollution. (ii) Soil becomes unsuitable for farming and breeding. 4. What type of gas when released into the atmosphere causes global warming? Chlorofluorocarbons/CFCs
