Study the picture (factories and vehicles emitting smoke, with a person coughing) and answer the questions:
Write one measure to reduce this pollution.
Topic: Control of air pollution
Answer
Use UNLEADED PETROL or CNG in vehicles instead of diesel and leaded petrol. (Also acceptable: fitting chimneys with filters or electrostatic precipitators; switching off engines when not in use; using public transport or car pools; planting more trees; regular servicing of vehicles.)
One measure, stated concretely. Vague good intentions ("we should stop polluting") earn nothing.
Measures fall into three kinds, and naming which you are giving shows structure: TECHNICAL — cleaner fuels (CNG, unleaded petrol), filters and precipitators on chimneys, catalytic converters BEHAVIOURAL — public transport, car pooling, switching off engines at signals BIOLOGICAL — planting trees, which absorb carbon dioxide and trap dust on their leaves
Delhi’s conversion of its entire public transport fleet to CNG by order of the Supreme Court is the standard Indian example.
