Watch on YouTubeVideoWater scarcity and conservation
Though Earth looks blue, only ~2.5% of all water is fresh. Most is locked in ice caps and glaciers; only a tiny fraction is accessible liquid fresh water.
Ways to save water:
- Fix leaking taps and pipes.
- Close tap while brushing.
- Shower shorter; bucket beats hose.
- Rainwater harvesting — catch and store rain.
- Drip irrigation on farms.
- Reuse greywater for plants/flushing.
Example
A dripping tap wastes ~15 litres a day — that's 5,400 litres a year, enough drinking water for one person for 7 years.
💡 Tip:"Every drop counts" isn't a cliché — it's literally true with freshwater scarcity.
