Water, water everywhere – but for how much longer?

Enviroment

Demand for water is expected to increase by nearly one-third by 2050 as the planet’s population expands, according to the 2018 World Water Development Report from the United Nations.

To provide enough water for drinking, growing crops, generating power and other uses, governments and businesses should work more closely with nature, which controls the water cycle, the report said.

Incorporating more green space into cities, conserving wetlands, and farming in ways that keep the soil healthy are examples of the “nature-based solutions” backed by the report.

These can also help protect people from floods, drought and other water-linked threats, it said.

Here are some facts on water use, and the risks of too much or too little water.

* Global water use has increased by a factor of six over the past 100 years, and is growing steadily at a rate of about 1 per cent per year spurred by population growth, economic development and changing consumption patterns.

* Household water use accounts for about 10 per cent of global water withdrawals, and is expected to rise significantly by 2050, particularly in Africa and Asia where domestic demand could more than triple.

* Global demand for agricultural and energy production – both of which use water intensively – is expected to increase by about 60 per cent and 80 per cent, respectively, by 2025.

* Agriculture accounts for about 70 per cent of all water use worldwide. Water withdrawals for irrigation have been identified as the main driver of groundwater depletion.

* Worldwide, 3.6 billion people, or nearly half the global population, live in areas at risk of being water-scarce for at least one month a year, nearly three-quarters of them in Asia. The number could increase to 4.8 billion-5.7 billion people by 2050.

* At about 4,600 cubic kilometres per year, global water withdrawals are now already near maximum sustainable levels.

* Since the 1990s, water pollution has worsened in almost all rivers in Africa, Asia and Latin America.

* An estimated 80 per cent of industrial and municipal wastewater is released to the environment without treatment, resulting in a deterioration of overall water quality with harmful impacts for health and ecosystems.

* About 30 per cent of the global population live in places routinely hit by either floods or drought.

* The number of people at risk from floods is projected to rise from 1.2 billion today to around 1.6 billion in 2050.

* Some 1.8 billion people are affected by land degradation, desertification and drought.

* Since 1900, an estimated 64 to 71 per cent of the world’s natural wetland area has been lost due to human activity.

    Anybody figure out that Trump is a doofus? Anybody figure out the doofus is still making money for the deep state?

    He ain’t draining the swamp, he’s enriching it, whether it is beknownst or not, that is what is happening.

    Can’t possibly be any other way.

    75 Kilograms average weight for each human, 70 percent water, 52.5 kg of water in each human, the average, times 7.6 billion equals 399 000 000 000 kg of water in all humans.

    All need four glasses of water each day, two liters, 2 kg of water each day.

    798 billion kg of water each day for all humans just to keep the water intake adequate for the body to function properly.

    Also, the human population blazes through one hundred million barrels of c/c each day, without that amount of oil, it will be bad from day one.

    Can’t go without water, you’ll die.

    Can’t go without oil, it will be all over but the crying.

    Cut it, slice it, dice it, that is how it is.

    Water is too cheap and abundant. As it becomes more scarce and expensive we will be forced to use it more efficiently.
    Russia has a lot of water; they will never run out of it. Humanity will go extinct before Russia runs out of water. Viva Putin! Viva Rusia!

    Maybe jezus will come along and remove all the oil, plastics, nuclear waste and old tires the narrativeman and friends have been dumping into our water supplies for the last hundred years or more. You cant have an honest discussion about how much water there is to be had without considering what is IN the water that is available. Water supplies are simply becoming increasingly contaminated by industrial and consumer waste everywhere. Ask the people in under-developed regions of the world, like Flint Michigan.

    Even the corporate-friendly media, always happy to downplay and deflect attention away from corporate malfeasance, covered this story. Of course, this is only the tip of proviberal melting iceberg when it comes to water pollution.

    A growing population makes all problems harder to solve.

    Too many people demand too many resources.

    Me and Michimind ain’t worried about running out of water here in the mitten. We are terrified about being overrun by thirsty Southwesterners.

    We can solve the water shortage by
    watering the crop fields with ocean water.
    It’s impossible to run out of ocean water.
    Everybody knows that.

    Correct. More and more, it’s not the quantity of water, but its quality. Just ask China where a large percentage of water resources are so polluted, it can’t even be used for industrial purposes. Ask the recently extinct Yangtze River dolphin about pollution and its effects. The Dump administration eliminated the requirement that chemical companies test new compounds for adverse impacts on the environment prior to release. Dump’s EPA administrator and former industry lobbyist claimed that this “Democrat: job-killing legislation was costing jobs (in reality, he meant to say costing the chemical industry less than a penny a share in earnings). Nobody bothered to ask since when was Pruitt concerned about the welfare of rank and file workers.

    Kenz300:

    I like how you cut to the meat of the matter. Well done.

    “The Dump administration eliminated the requirement that chemical companies test new compounds for adverse impacts on the environment prior to release.”

    Do you have the reference because your shallow highlight sounds extreme and emotionally slanted. “Completely eliminated all testing” sounds extreme and beyond what I would expect would fly out of Washington.

    Der Hund, the guy hates Americans and especially hates Americans that talk bad about China and you are buddying up to him????

    Davy,

    Under Missouri law, is it legal to pledge allegiance to a flag manufactured in China?

  11. Davy on Tue, 20th Mar 2018 10:59 am 

    No, but pricks generally get their ass kicked. Why? Just because pricks need an ass kicken. It’s considered common law.

  12. GregT on Tue, 20th Mar 2018 11:37 am 

    It was a legitimate question Davy, and who better to ask then an totally obsessed, and prolific flag waver such as yourself?

    Thanks for your usual considerate and mature response. I found the answer online instead.

    It would appear that legislation was passed for the US military to wave only flags proudly ‘Made in America™’.
    Sadly, 94% of all imported US flags are still manufactured in China, including those used by the US government itself.

    So no, it’s not illegal to pledge allegiance to Chinese flags.

    greggie, your question is a prick and you are a prick. I have kicked your ass so many times all you think about is pricking me. Man up and show some intelligence IOW say something on topic and enlightening. You are sinking into irrelevance day by day. Maybe you will fall off the board like all the other pricks that have vanished.

  14. GregT on Tue, 20th Mar 2018 2:23 pm 

    “IOW say something on topic and enlightening.”

    Merely responding to your post above Davy:

    “the guy hates Americans and especially hates Americans that talk bad about China and you are buddying up to him?”

    And wondering why you hate the Chinese so much, especially considering the fact that without them, the US economy would already be DOA.

    Exceptionalist turd craps this out.

    “No, but pricks generally get their ass kicked. Why? Just because pricks need an ass kicken. It’s considered common law.”

    Just as exceptional amerika is the ‘law’ and world policeman’, so to, here at PO.com, the exceptionlist has appointed himself, the ‘law’.

    Needless to say, amerika’s role of ‘world policeman’ is a self-appointed one and done entirely for selfish reasons. See the similarity? Despite being reminded countless times, you have no position or special status here exceptionalist, yet you continue to cast yourself in the role of some kind of self-styled, white-hat sheriff. You seem to think the world, and the forum here, since it comprises the scope of the ‘world’ as you know it, is one of those old amerikan cowboy serials you watched on TV in the 1930s and 40s.

    One last thing dumbass. Why is ‘Hiya’ considered somehow low-brow to you(if I use it), but ass-‘kicken’ is ok when in your usage?

    As a further aside, the proper colloquialism you were looking for, would be ass-Kick’n, not ass-kicken.

    Dumbass.
