why is rainwater important?

Question

what are some reasons why rainwater is important...please state your sources~

Answer 1

Hey, just tell your teacher that there are places where there is absolutely no rainwater at all; the Atacama desert in Chile, and that the lifeforms there survive thanks to humidity from the sea. For them, rainwater isnt important at all.

Answer 2

Rainwater is ultimately significant because of Rainwater Collection..a system that provides people with water they "need". In some places, rainwater collection is their ONLY source of good, clean water. It's also significant during times of drought. There are other reasons as to why rainwater is important, relating to the environment of course. However I believe rainwater collection is most significant..

Answer 3

because the bio mass exists because of it

and the forrests are important

tAPART FROM THE FACT THAT EXOTIC FORREST STILL CONTAIN COUNTLESS MYSTERIES OF MEDICINAL VALUE.
they are also the prime factors responsible for the climate that is suitable for human ocupation.

and we have proven (in south africa,Europe,Mexico,USA,and just about every where else)that the forrest are far more valuable in terms of Eco-tourism than for example farming or timber(which has a very short lived value).

TREES NOT ONLY PRODUCE OXIGEN or ABSORB CARBON
the world bank pays large subsidies for farmers to plant trees especially a tree called Pawlomia because it is one of the better ones that capture carbon.

plants take in carbon dioxide period they dont take in oxigen at night.

they require carbon dioxide and release oxigen.

in the autemn there is an excess of carbon released because of the dead organic material ,the seas and waters when cool absorb this,in the spring when the new growth requires carbo the warmer waters release it ,so in con junction with the seas and rivers the bio mass on this planet maintains a balanced atmosphere for us to breathe.
now with the mass deforrestation(decrease in bio mass)coupled to the increase in carbon emissions,industrial chimneys,aerosol cans,motor cars,burning of plastics and tires to name but a few ,the carbon production by far exeeds what the bio-mass and the waters can handle,and so effect into global warming and the destruction of the ozone layers,
so to counter act these fatal processes we must reforrest and at the same time reduce our carbon emissions.
most governments are aware of these and many first world countries now include programs to reduce their carbon emissions.

the forrests make most of the water that we can drink or use for plant growth(sweet water)
some is condensed from the sea but that reaches only the coastel aereas .
the bulk ,comes from the forests ,and the rivers come from the rainfall which comes from the trees ,
and the trees with precipitation,feed the rivers when it is not raining and keep them running all year round.

DEFORRESTATION if it continues ,is that we could end up looking like Mars.Without an atmosphere ,without water,without air,with out life
If we kill all the trees,we kill the rivers .we kill the rain. we kill us.

the trees also absorb the heat in the day and heat up the place in the night ,so they keep the temperature confertable to live in.
these are some of the reasons why trees are important.plant a tree every week,and help us save the world

DESERTIFICATION
desertification is also a result of bad agricultural methods and deforrestation
in the dessert the nights are freezing cold and during the days you burn up

the saharaa is growing by 7 kilometres every day.
two major desserts in northern china are growing together making one giant dessert and,causing dust storms so making thousands of people refugeese

the trees evaporate a mist which ,which protects us from the strong rays of the sun .

in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth ,and there were no desserts .

Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.

Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.

Bad agricultural practises is turning vast teritories into desserts ,because of over grazing and the exessive pumping of carbon aquifiers ,the surface aquifiers already having been depleted.
And the use of fertilisers and heavy machinery that compacts the ground which raises the salt in the soil.
Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.
farmers are forced to cultivate highly erodable lands, to keep up with the growing demand for food.an extra 70 million people each year and this is increasing

the world population has doubled in the last 50 years the fasted increase ever since the first homo sapian. Source(s) http://spaces.msn.com/byderule

Answer 4

All living things need 2 elements in order to survive.

Water & Oxygen. Food can be preyed when hungry or endure hunger but not without water and air.

Humidity is water vapor in a gas. Water vapor consists of individual water molecules moving independently and randomly of one another, suspended within gas.

Individual water molecules are too small to see, as they are only one-ten thousandth of a micron in size.

Answer 5

Just like we use water to wash when it rains its a way of cleaning the air and atmosphere cooling and cleaning as it falls. It hydrates all living things like plants, animals, seas, rivers, trees, in order for things to grow and flourish thus giving life !

Answer 6

Without rain, the earth's water would just keep evaporating and we would eventually run out of water!

Which is one of the most important elements to our survival.

Answer 7

with ouy iy we would run out of water cos it'd all evaporate and be gone 4eva
