    What do you know about water?
    Water is our planet’s most valuable resource. It is rare in some parts of the world, which makes it particularly valuable

    The total volume of water on Earth is about 1.4 billion km3. The volume of freshwater resources is around 35 million km3, or about 2.5 percent of the total volume. The world's six billion people are appropriating 54 percent of all the accessible freshwater contained in rivers, lakes and underground aquifers. The UN suggests that each person needs 20-50 litres of safe freshwater a day to ensure their basic needs for drinking, cooking and cleaning. The daily drinking water requirement per person is 2-4 litres, but it takes 2 000 to 5 000 litres of water to produce one person's daily food. In developing countries, 70 percent of industrial wastes are dumped untreated into waters where they pollute the usable water supply.

    Tanzania we are very poor on water supply and very good on directing wastes to the water
    i hope the minister responsible for water has to start good planning before it get out of control

    please treat water resources with a great consideration as soon or late it will be expensive as gold
