With sea levels rising why can't we irrigte the deserts, we built the suez, Panama and crinin canals why not?

Answer 1

You can do it. Israel changed entire deserts into productive farms.

Of course, process is little bit expensive, but people are not interested in solve problems. Only profit.
Why have better prices to computers if it will destroy your national industry? Why buy meat from Brazil (more than half price) if it will destroy local farmers?

World fighting agains poverty or freedom or human rights are just an urban legend. Always there any kind of business rule behind any action.

What i do not know is what is the relation between Sea Level Rising, Artificial canals and Irrigation. At least final two have any kind of far association through human capability, but to poetic.

Answer 2

When a conqueror would really want to decimate a culture and make absolutely sure that it would never bother his empire again, he would “sow the fields with salt”. IT MADE a desert. A natural desert could, many hundreds or thousands of years in the future, recover and establish an organic matrix (what we call “soil”). But a salt flat is a salt flat.

Answer 3

Mostly because the Sea water would be to Saline and present desalinization units are not really capable of a project of this magnitude.
Desalinization best on small individual scales.

Answer 4

The seas are full of salt.

Salt kills plants.

You would need to build desalination plants to get the salt out of the seawater before it can be used for irrigation.

Answer 5

we have done this. look at saudi arabia. they have one of the world's largest desalination units. it is used for drinking water and to irrigate their farms.

so, in my opinion, when the poor desert dwellers find oil, gold or uranium, we will irrigate their deserts for them, since we are such nice people....for a price, that is.

Answer 6

i believe it is because of the climate, despite the fact we would probably have enough water for it it would still be very hot in the desert so the water would evaporate quickly which in turn would completely reverse this and limit our water supply

Answer 7

its not possible coz the temperatures n heat rise very often and als that no one wud agree to do that coz they will just die off heat there, just think who wud evwer want to move from their sweett homes to desertss whichr also a simple examples of rural areas too!

Answer 8

sea water contains salt
desserts tend to be in dodgy places like iraq
people living there can't afford your plan

Answer 9

You can't irrigate with salt water.

Answer 10

Because it cost too much....

We CAN do it but we dont WANT to do it...

Sad but the world is run by MONEY....
