That question can not be answered. The closes answer is more than 3/4's of the world is water.
According to one source ("How Stuff Works") It is estimated that there are about 326,000,000,000,000,000,000 (three hundred and twenty-six million trillion) gallons of water on Earth, including the oceans, rivers, lakes, underwater springs and wells, the ice caps, atmospheric vapour, and the fluids in your body (and in everything else, too). The oceans cover about 72% of the Earth's surface, but constitute about 98% of the Earth's water, so less than two percent of the world's water is actually 'fresh' (ie- drinkable), and with three quarters of this locked up in the ice caps and majority of what's left being underground, only a very tiny fraction of the world's water makes up rivers, lakes, and ponds.
Without water there can be no life and Earth. So, if we have to save our planet we need to conserve water. Sadly, water levels in many parts of the world have dropped alarmingly.
