She found more information about water.456More information about water7891011A2 Read the information Daisy found.11-2123456The oceans cover 2/3 of the Earth, but ocean water is salty. That is to say, most of the water on the Earth is not drinkable!
90% of all the water on the Earth that human beings can drink right now is underground. It is very easy to pollute groundwater. For example, 4.5 litres of paint or about 1 litre of motor oil can seep into the Earth and pollute 1,125,000 litres of drinking water!7891011More information about water11-3123456A leak that fills up a coffee cup in 10 minutes will waste over 13,500 litres of water in a year. How much water is that? You would have to drink 65 glasses of water every day for a year to get that much water!
If you leave the water running while you brush your teeth, you might waste 22.5 litres of water. That is enough to fill 65 cans of soft drink!
If you leave the water running while you wash the dishes, you might waste 135 litres of water—enough to wash a whole car!789101111-4123456Believe it or not, the water we flush down our toilets starts as fresh water! Each time you flush, your toilet uses about 9 to 15 litres of water. But it does not have to!
A shower usually takes at least 5 minutes. So every day, you could use 112.5 litres of water taking one shower. In a year, that is almost 45,000 litres of water!
A bath uses even more water than a shower—about twice as much. A bath can easily use 225 litres of water.7891011B Match these words with their meanings.debcfa11-51234567891011C Read the article again. Then work in groups of four.
