Sources of fresh water
Sources of salt water
Conserving fresh water
Conserving fresh water means using water in a correct way, because the percentage of fresh water that is suitable for drinking is very small compared to the percentage of water on Earth.

So, we must conserve the limited amount of fresh water through many ways such as:
1 Drinking more juice instead of water.
2 Turning off water tap (faucet) during brushing your teeth.
3 Taking a quick shower.
4 Turning off the water, while washing your hair.

بالتوفيق
