IF THE EARTH HAS ALWAYS THE SAME AMOUNT OF WATER, AND IT ALWAYS
FOLLOWS THE SAME CYCLE, WHY MUST WE SAVE OUR WATER?

WE HAVE TO SAVE IT BECAUSE...
• We have done an experiment, and we have seen that the water can underground flow. Here we can see the difference.
A FORM TO WASTE IT
• If you don’t close the tap of the water, you are wasting it. We have done another experiment and we have seen that in Catalonia we can waste 1.892.750 of litres in a day, if we let running the water.
THE ANSWER
• We have to save the water ( althouhg we have got always the same), because...
1- The distribution of the water. There is a lot of saltwater, a 97% of it. We only have got a 3% of freshwater.
2- But from the 3% of the frehwater, there is some ice that we can’t use. There is also some underground flow. We can’t use this water, so we can only use the 1% of the freshwater.
3- The pullation is another way that know that we have to save the water, because we can’t use the polluted water. So, a lot of countries have got a Depurator to clean the water.
THE END
