• Smoke from industrial and domestic burning of fossil fuels produces gases like nitrogen, carbon dioxide and sulphur dioxide
Acid rain is the term to describe polluted rainfall. The moisture in the atmosphere mixes with gases like sulphur dioxide and carbon dioxide, forming a weak acid. Acid rain affects the plant and animal life of rivers and lakes by reducing the numbers of some species.
• Carbon monoxide from exhausts of cars • Sulphur dioxide from traffic and incomplete burning of fuel • CFCs (chlorofluorocarbons) used in old fridges and aerosols • Overuse of chemical sprays and cleaning agents
Effects
• Global warming affects the earth’s climate • Ozone layer is damaged which leads to skin cancer and eye damage • Increase in respiratory conditions like asthma and bronchitis and allergies
• Acid rain lowers pH of soil so damages plants and wildlife; it also damages metals and stone
Steps
towards change
• Use renewable energy resources • Avoid products with CFCs, choose pump-action and ozone-friendly products
• Use smokeless fuels and unleaded petrol • Use cars less, so car-pool, use public transport, or walk or cycle more
• Buy energy-efficient appliances • Use green/organic cleaning products and detergents
