Question

Will there be enough water for everyone in 50-100 years from now? Support your answer.?

Answer 1

yes, we will have water. wether or not we will be able to afford it is the question. you can always make water. you have hydrogen and oxegyn in an abundance amount. the only thing that you have to worry about it being able to afford it when we have to start making it. the government likes to take money and once they figure out that we are buying it, they will increase the price for it.

Answer 2

The  problem with water is distribution, not supply. Every day cubic MILES of water flow out of the Amazon into the Atlantic Ocean. The  current can be felt 50 miles offshore. Other major rivers do the same thing, on a smaller scale.

Sea water can be made into drinking water by several methods. There is about 100 million gallons of sea water for every person on the planet.

There is also 6 million cubic miles of ice on Antarctica. We do not want it to melt, as this would raise the level of the oceans 212 feet, but some of it could be used.  

The Great Lakes hold 5% of the  planet's fresh water, but that does not help a thirsty person in Arizona.

Answer 3

if we are desperate we can use desalination plants to drink beach water

Answer 4

Yes, there always has been enough water for the planet ever since Earth was created and always will be

rain water is recycled water

use your imagination

Answer 5

If I had my way there would be. I have a comprehensive system for the bioremediation of eutrophic water bodies. I was on a team that spent a year in Lake Elsinore, CA looking at the environment, watching the daily ebb& flow of the watershed (winds etc.) and kept trying to use that ebb & flow to power most of the system.

Nobody would listen to our development group when we wanted to test the system using an actually polluted lake. The local water district was too busy pocketing the EPA funding sent for bioremediation. They're trying different things now after almost 10 years, but their efforts are a joke. All anyone need to do for me to demonstrate how to fix ANY eutrophic waterbody is ask, and bring a checkbook.

Answer 6

the future wars will be for potable water someone once said

not a drop of water ever leaves the planet ,but it changes its form ,and location.

75% of the worlds potable water supplies are being lost into the seas,

And much of the little that is available is being contaminated

and we have an extra 70.million people each year that drink wash ,waste water ,not to speak of the extra irrigation needed to grow the extra crops to feed all these new additions

farming alone uses more than 60% of all water supplies.

This has brought the good(sweet) water supplies to critical levels ,

Perhaps there is plenty of water where you are ,but

some countries have been in trouble already quite a while .

In Tasmania 1 liter of good drinking water is worth 2 liters or petrol

In Southern Portugal and southern Spain ,Wine is cheaper than water

and the food you buy comes from many third world countries that have mayor irrigation problems

When the price of beer goes up because of the water it uses ,you will know that we are in big trouble .

here is a story on water shortage

WATERSHORTAGE

we should not only conserve water ,we should also collect it

PERMACULTURE ANSWER ON WATER HARVESTING AND CONSERVATION

WHY SHOULD WE HARVEST WATER

because there is so little that we can use

------------------------------...

25% of the planets surface is land

75%of the surface is water and it is rising

------------------------------...

97%of the Earths water is salt

fresh water is only 3% of all the Earths water

most of it is beyond out reach

now much ice is melting and running into the seas fresh water lost for ever.

STORAGE or Location of % of the fresh water

ice and glaziers 74%

groundwater 800 meters + 13.5 %

groundwater less than 800meters 11.o%

Lakes 0.3%

soils 0.006%

Atmospheric in circulation 0.0035%

rivers 0.03%

frozen land or permafrost is not included and represent an unavailable storage of 40%

so of the 3% about 11.6 ,is easily available to us ,in rivers, lakes and ground water surface aquifers,more and more of this is becoming contaminated

.

Now climate change and desertification, because of irresponsible agriculture ,overgrazing and deforestation is damaging world fresh water production .

It is a good reason for concern and if we do not rectify matters by changing agricultural methods ,reforest ,stop deforestation,become more economic with water use ,stop producing more people ,stop wasting and contaminating water, we will be in serious trouble all round

and could end up looking like Mars

And these are some of the things we can do

tp conserve water use

EFFICIENT WATER USE

IN THE HOUSE and GARDEN

one can connect the sink straight to the toilet cistern and so use the water twice ,first to have a shave and then to flush the toilet

also if you bend the ball valve you can regulate the level of the cistern

Always have your Grey water and Black water separate,so that the sink and shower water goes directly into the garden saving on irrigation and at the same time ,making the sewage smaller and easier to deal with ,

This also goes and irrigates the garden but via a cistern of two compartments and a French drain ,on which you plant trees,

when it rains ,make your lawn and garden receptive to absorb water ,and not let it run off onto the street.

And cars can be washed with rain water ,it does not have to be drinking water.

The summary for the garden is mulching and lowering the flower beds

having the paths high so that they form basins that absorb the water .

ON THE LAND

Economic systems of irrigation, like drip irrigation

and water harvesting design, using a lot of stone walls ,that condense water in the night

and planting leafy plants ,for the same purpose,

Building wind breaks ,to counter act the drying effects of the wind and farm towards Aggro forrestal ,using as many trees as possible to limit evaporation .

Using shade nets before we have tree cover

and use MULCH

By cutting down the weeds before they produce seeds and leave them where they fall.

They will cover the ground add even more organic matter on top,(you can use saw dust,leaves green or dry),

And when you plant make a little space and plant in the mulch.this is the easiest quickest and by far most beneficial way(for the quality of you soil)to prepare the land for planting.

To prevent weeds from coming all you have to do it turn out the lights,you can even use cardboard or black plastic(this is good for strawberries because they will rot if they touch humid ground,and the bugs can get to them).

Mulch is organic material green or dry that covers the ground,the thicker the better the composting process will turn it in to black topsoil

The humidity is preserved underneath and promotes the development of worms(there exists no better compost than their excrements)and a variety of micro biotic life which together within the mulch produce more topsoil.

The mulch also keeps the ground temperature even and guards against the impact of the rain ,which would other wise brings salt to the surface if on unprotected land.

Mulch also prevents the soil from drying out because of the sun and,wind erosion.

WATER HARVESTING

As far as catching rain is concerned ,we do this all the time ,and have done so already since Babylonian times,and is a part of the more advanced Agriculture,that existed with the Egyptians,,Moors, Arabs and probably many more

Central ,and South American indigenous people had this idea coupled to their pyramids ,catching the water of the slopes and leading it into tanks or onto the fields .

And many others ,today we call this WATER HARVESTING.

Only Modern Man is totally extravagant with the rain water given ,and complains of the wetness ,letting it run off into the rivers lost forever ,With out even attempting to hold on to it .

And then later complains of not having water ,when times are dryer

In Permaculture the rule is to harvest water to the point of Zero runoff.

This means that all of the rain that falls on an area is absorbed by the terrain and not a drop leaves it.

By building dams,ponds or Swales, with inter connecting ditches,

http://answers.yahoo.com/question/index;...

.

If there are enough of these ;the places ,where before ,the rain water ran over the ground into the rivers and on to the sea ,in a matter of minutes or hours

It now runs into absorbent dams or Swales and saturates the ground and eventually reaches subterranean water deposits ,taking many months to do so.

Or it fills up ponds that can be used for Aquaculture.

And so a convex situation that repels water is transformed in a concave ,absorbent one and turning the area in to a sponge.

In Spain and Portugal ,which still display many examples of the conquering Moorish influence one can find many remnants of Water harvesting,such as Aqueducts and tanks underneath the patios ,which collect the rain water from the roofs ,to be used in dryer times.

In Arabia ,on a large scale ,land has been shaped to catch and lead,rain water into sandy areas or to agricultural lands.sand is almost as good as dams because it absorbs water and holds it.

Here in Mexico we collect the rainwater in our school for sustainable agriculture,but it is too near Acapulco to trust the rain water for drinking ,and this holds true for most places ,so we use it for irrigation.

the rain water from a gutter runs via a filter into a tank.

In Europe in my parents house ,when i was young ,we had a rain barrel,where the water from the gutter ended up .

this was usual in those days ,but i have seen few in modern times.

We can use this action also in other ways ,

for example the roof water via a ditch can run trough the chicken house ,cleaning it and end up fertilizing the vegetable plot(this is called the creation of energy flow.

this water used to be Ok in times gone by before Air pollution ,

Today i would recommend it only for washing and irrigation

Answer 7

It Will End Up finishing Soon! water Prices Are Gonna Go up Like gas prices

Answer 8

There isn't enough water for everyone already.

Answer 9

There are already serious water shortages around the world.  The NE US had a drought a few years ago and Florida and Georgia and experiencing a drought now.

Water really doesn't disappear, but it does move around the world a bit.

A better question would be 'Will there be enough clean water in 50-100 years?'.

Answer 10

There will always be enough water but will it be potable is another question. I think the water quality may diminish unless this resource is protected and toxins are cleaned from the environment. If you are speaking world wide. There is, and was, a shortage of clean safe water to drink or even bathe in.

Answer 11

i wish i knew. Our society is way to wastefull.

Answer 12

We have a fixed amount;-} the question is drinkability.

The oceans are become more polluted, killing off marine life.

But global warming makes ice-bergs melt, to dilute this.

Answer 13

there is more ocean then land

Answer 14

i think we can create water H2O???

Answer 15

Ditto on the above.  I don't know if there's enough water for everyone *now* -- checked out the middle eastern water fights lately?

Will there be enough water for everyone in 50-100 years somewhere in the world?  Sure.  The technologies to filter seawater keep getting better and better, so we will probably be able to keep up with global demand for quite some time.  Transportation to the areas that need it may be another issue entirely, just as it is today.
