In ancient times, the world provided
living things with sufficient amount of potable water through freshwater ponds,
lakes, and streams among others. Unfortunately, the rapid surge of population
growth and environmental damage greatly reduced such availability of drinkable
water, thereby pushing man to find ways on how to maximize other water sources.
According to the United Nations, around
1.8 billion individuals are predicted to live in areas with scarce water supplies
by 2025. Increasing industrial demand, droughts, and population growth are
primary contributors of water shortages in the world.
