Class 5 Our Wondrous World – The World Around Us – Chapter 2 Journey of a River question answer
(a) Keep the river clean
To keep the river clean, I’d ensure industries treat wastewater before release, build sewage treatment plants and enforce strict anti-dumping laws. Citizens would be educated on eco-friendly habits. Plastic use would be reduced and riverbanks cleaned regularly. Eco-clubs in schools and campaigns would involve the community. This would preserve aquatic life and ensure the river remains safe for all living beings.
(b) Prevent floods during heavy rains
To prevent floods, I would design the city with proper stormwater drainage and green spaces to absorb excess water. Flood-prone areas would have embankments and sandbag stations. Forested areas near the river would reduce runoff. A warning system would alert people early and emergency shelters would be built for safety. This ensures both human lives and animals are protected from flood disasters.
(c) Ensure there is always enough water for everyone, even during summers
To ensure water during summers, I would build reservoirs and promote rooftop rainwater harvesting in every building. Treated greywater would be reused in gardens and toilets. Water ATMs would provide access in public places. Laws to prevent water wastage, community storage tanks and educating citizens would make usage efficient. Groundwater recharge zones would be created to store water naturally and sustainably for year-round supply.
