NAME:
WORLDWIDE WATER CONSUMPTION TRIPLED IN 1950. BUT OUR PLANET'S WATER RESERVES DID NOT FOLLOW THE INCREASED CONSUMPTION, SO CONTINUED AT THE SAME LEVELS.
WHAT ALSO DRAWS ATTENTION IS THAT IN RECENT DECADES THE AVERAGE WATER CONSUMPTION HAS EXPANDED BY 50%.
USING AN OPEN TAP FOR 5 MINUTES TO BRUSH YOUR TEETH OR SHAVE, AN AVERAGE 12 LITERS OF WATER IS USED. SOME WAYS TO SAVE UP TO 2 LITERS OF WATER ARE: BRUSHING YOUR TEETH USING A GLASS OF WATER, SHARING BY PLACING A PLUG IN THE SIN.
A TAP THAT DRIPS FOR A ENTIRE DAY USES ABOUT 48 LITERS OF WATER. ANOTHER ATTITUDE THAT WASTES A LOT OF WATER IS A LONG BATH.
A DISCHARGE WILL USE 19 LITERS OF WATER. SO IT IS RECOMMENDED THAT THE OLD DISCHARGE VALVES BE CHANGED FOR NEW VALVES THAT HAVE TWO DISCHARGE OPTIONS, AND FOR THOSE WHO CANNOT CHANGE THE DISCHARGE, UNNECESSARY DISCHARGE AND PROLONGED.
WE MUST BE AWARE THAT WATER IS AN ESSENTIAL GOOD FOR EVERYONE'S LIFE, AS WE CAN GO UP TO 28 DAYS WITHOUT EATING, BUT ONLY 3 DAYS WITHOUT WATER.
1) COPY ALL NUMBERS THAT APPEAR IN THE TEXT:
R.:
2) KNOWING THAT A DRIPPING TAP SPENDS 2 LITERS OF WATER PER HOUR, ANSWER HOW MUCH IT WILL SPEND ON:
3) AN OUTLET WASTES ABOUT 19 LITERS OF WATER. FIND OUT HOW MUCH WATER EACH HOUSE WILL SPEND WITH DISCHARGE IN ONE DAY.
