Human Right

We live

in the Blue Planet, the Water Planet. However 1100 million people haven’t got the access to drinkable water ensured and 

about 20000 die 

every day because of it, most of them are children.

On average we have sufficient water to meet human needs.

The problem is water distribution.

We need to stay hydrated to remain alive, because we are

55 – 75% water!

The water in oceans (75% of the earth’s surface) affect climate and store heat.

Plants use solar energy to grow: water is the catalyst that helps in this process.

Water vapor in the atmosphere traps radiation and warms up

the Earth.

Water is a crucial element of our food and materials

World water uses

Different uses of water • consumptive usage is diversion + consumption of the water

through– transforming it into water vapor (where it is “lost” to the

atmosphere), – letting it seep into the ground, or– significantly degrading its quality. For example

• Residential• Industrial• Agricultural• Forestry

• non-consumptive usage. Do not educe water supply and, frequently, do not degrade water quality. Examples – Fisheries use water as a medium for fish growth.– Hydroelectric users extract energy from the water.– Recreation may involve using water as a medium (example:

swimming) and/or extracting energy from the water (examples: white-water rafting, surfing)

– Transportation is especially important use of water in the tropics.
