Why is rainwater harvesting important in Tamil Nadu?
Rainwater harvesting is mandatory in Tamil Nadu because it helps recharge depleted groundwater levels, ensures a steady water supply during dry summer months, and reduces urban flooding.
How can an individual reduce their carbon footprint?
An individual can reduce their carbon footprint by using public transport or carpooling, conserving electricity, minimizing single-use plastics, planting trees, and adopting energy-efficient appliances.
