Only 5% of the water on Earth, our Blue Planet, is fresh water (rivers and underground water tables).
Only 0.3 % of these 5% of fresh water is accessible. Most of the rest is locked up in ice caps and glaciers.
The constantly growing world population must rely upon this small amount of water to survive.
Based on current rates of increase in water demand, by 2025, two thirds of the world's population could be short of drinking water.
20% of the world's population currently doesn't have access to drinking water and half of the population isn't connected to wastewater treatment facilities, so this affects nearly 3.5 billion people.
Without sanitation, conditions are highly unhygienic and prone to conveying infectious diseases. It is assumed that the lack of sanitation is the cause of the death of over 2.5 million people in the world every year. Today, wastewater treatment is a priority in developing countries.
More than half of pesticides or herbicides used in gardens or fields find their way directly into the water and end up in rivers and underground water tables.
