How Much Water Do We Use
Key notes :-
1. Importance of Water
- Water is essential for life. We need it for drinking, cooking, cleaning, agriculture, and many other activities.
- Around 71% of the Earth’s surface is covered with water, but only 1% is fresh and usable for humans.
2. Everyday Water Usage
- Drinking: A person needs about 2-4 liters of water per day for proper hydration.
- Washing: Water is used for cleaning dishes, clothes, and our bodies (showers, baths).
- Cooking: Water is essential for preparing food (boiling, steaming, etc.).
- Toilets: Flushing toilets use a large amount of water (around 5-7 liters per flush).
3. Water Usage in Agriculture
- Agriculture is the largest consumer of water. Crops like rice, wheat, and corn need a lot of water.
- Efficient irrigation systems are important to reduce water wastage in farming.
4. Water in Industry
- Industries use water in manufacturing processes, cooling machines, and generating energy (power plants).
- Factories and industries can consume vast amounts of water, sometimes contributing to water shortages.
5. Water Wastage
- Wasting water through activities like leaving taps open, long showers, or using water inefficiently contributes to water scarcity.
- Fixing leaks and reducing water consumption in daily activities can help conserve water.
6. Conserving Water
- Simple actions: Turn off taps while brushing teeth, use water-efficient appliances, and take shorter showers.
- Rainwater harvesting: Collecting and storing rainwater can reduce dependency on other water sources.
7. Global Water Scarcity
- Many parts of the world, especially in dry and arid regions, face water scarcity.
- Overuse and pollution of water sources contribute to the global water crisis.
