The document discusses the importance and uses of water resources around the world. It notes that only 3% of the Earth's water is freshwater, with the majority being icecaps and groundwater. Asia contains over 60% of the world's water resources while supporting 36% of the global population. Water is used in homes for activities like flushing toilets, bathing, and washing clothes, as well as in factories and for agriculture. Agriculture relies heavily on water, as both plants and animals require water to survive. The document concludes by providing some facts about water and tips for conserving it at home.
2. The resources of water
• From the Earth’s water,only 3% in is freshwater, all the rest is saline
(saltwater from the oceans).Let’s look at that 3%! 68.7% of
freshwater are icecaps and glaciers, 30.1% is ground water,0.9%
are other waters, and only 0.3% of freshwater is surface water
(that meens: 87%:lakes, 11%:swamps, and 2% are rivers).

5. The exploitation of water
• In our world we use water in many ways.We use
it to flush our toilets, to cook, to take a bath or
have a shower, to wash our clothes etc…
• Besides our homes we use water in factories, for
sports, for drinking, and many other ways and
different places.
• Water is the most important thing on the world,
besides oxigen.In the future water is going to
more important when the world runs out of oil
stocks.Even the cars are going to run with water.
6. Abstraction
• Abstractions for different uses exert the
most significant pressure on the quantity
of freshwater resources.
• The total water abstraction in Europe is
about 353 km3;/year, which means that
10% of Europe's total freshwater
resources is abstracted!
8. The importance of water in
agriculture
• We can split agriculture into two main
sections: plant and animal breeding.
• As we know the water has a very
important function in both, so important,
that if there would be no water, agriculture
wouldn’t even exist…
9. Animals
• We know that the animals need water
just as us, humans.
• Without water, all of the animals would
die in a few days on weeks. So to give
the animals freshwater to drink is
crucially if we would like to consume
animal products.
10. Plants
• Lets look at the plants.Besides the light,
plants need good water and even better
dirt.The ”good” dirt changes in the races
of plants, but the base of the good quality
of dirt depends on the water precentage.
• Without water, the plants wouldn’t exist
either, so water is the most important in
agriculture.
11. The importance of water in
fishing
• Fish are an important resource for
humans worldwide, especially as food.
• I think fishing would be pretty hard without
water.
• The animals which live in water, water is
like air for us.What would we do without
air?Nothing!
12. • In the future water is going to more
important when the world runs out of oil
stocks.Even the cars are going to run with
water.
• Right now the people just use to much
water, they don’t look ahead in the future,
and they don’t respect water because it’s
cheap.
13. • Human body is 66% water
• A living tree is about 75% water
• Almost 80% of the earth’s surface is
covered with water
• Water consists of 1 atom of oxygen
combined with 2 atoms of hydrogen(H2O).
