Direction: Read the following passage and answer the questions given after it.

“Water, water everywhere, but not a drop to drink.” You must have heard this phrase many times in your life. It means that although there is water all around us, in Earth’s oceans, seas, lakes, rivers, etc., most of it is not drinkable water! The oceans cover up more than 70 per cent of all of the Earth’s surface, which is why it is very easy to raise the question – then why do we say that there is a shortage of water? It is because the water in the oceans is so salty that it is not safe to drink it.

Thus, we must rely upon the other sources of water that the Earth provides us, from the rivers that come from glaciers. However, we must also remember that this water is limited, and will exhaust a few decades down the line. Therefore, it is very important to use this water responsibly and do everything we can to avoid wasting it. While there is a lot of water now, if we keep on using water for unnecessary things or wasting it, there won’t be much left around the world.

What if the water in the world finishes? Aquatic life such as fish, coral reefs, seahorses, etc. will not be able to survive, because they will lose their habitats. We humans will not survive because our bodies are made up of 70% water, and without it, we cannot sustain ourselves. All the plants and animals around us will become extinct too. The Earth, which is a planet characterized by its ability to house life, will not be what it is now.
