YOU KNOW WHAT IF YOU HAD A SYSTEM, WHERE WHEN YOU TAKE A SHOWER YOU PRESS THE BUTTON AND IT BEGINS TO COLLECT THE WATER WHEN YOU ARE TAKING A SHOWER AND IT USES THAT WATER TO WATER YOUR HOUSE GARDEN....And when you begin to soap yourself you press the button again and it stops collecting the water....And i was thinking...IF YOU WAS TO COLLECT THE ENTIRE PLANET WATERS FROM WHEN PEOPLE ARE TAKING A SHOWER NOT SOAPING THEMSELVES AND EMTPY THAT WATER IN THE SAHARA DESERT, I THINK YOU MIGHT FIX THE SAHARA DESERT OR HALF OF IT...
