Water in its natural state can be unsafe for human consumption. It may contain naturally occurring bacteria, inorganic material and man-made contaminants such as pesticides and pollutants. As a result, your water utility has to treat the water before delivering it to your home.
Why is the world running out of water?
The world’s changing climate has been linked to an increased incidence of droughts that can greatly diminish freshwater supplies in a region. The historic drought in California has depleted the Sacramento and San Joaquin river basins by an estimated 11 trillion gallons below normal seasonal levels.
What will happen if we drink polluted water?
Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year. By 2025, half of the world’s population will be living in water-stressed areas.
How much water on earth is drinkable?
Only about three percent of Earth’s water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground.
Is water free at Starbucks?
Free water If you like to drink water with your coffee (coffee can be dehydrating, after all), don’t pay for bottled water: You can get filtered water for free at Starbucks.
Should water be free or not?

Why does a small amount of water appear clear?
The reason a small amount of water appears clear is because not much light is scattered. In larger bodies of water there are more water molecules for light to collide with, resulting in more blue light being scattered. Think of it like throwing a bucket-full of tennis balls against a tree from…
Is it possible to find a cup of water that does not have net motion?
