Takie coś?
Water is a very important thing in our lives. Without it we wouldn't survive even a week. In oceans and seas we have salt water, which can not be drunk by humans. Fresh water is only 2,7% of Earth's water at all. Half of it is still not available - it's deep inside our planet or too dirty for our bodies. We need to remember about it and stop wasting water, because once we can regret it! There are a lot of ways to save water. We can, for example, take a shower instead of a bath. Arctic glaciers are also in danger - they are one of the biggest centres of fresh water, but they slowly melt and mix with salt water. We should remember, that 70% of our bodies is water and take care of it.
