Water demand to outstrip supply by 40%

Population growth and climate change could threaten the world's water supplies within the next 20 years.
Population growth will not only increase the demand for drinking water but also for that used in the production of clothing, food and other necessities. Developed countries will be required to have more complex water conservation techniques in order to manage the water that is available.
A new way of thinking about water is needed as looming shortages threaten communities, agriculture and industry, experts said. In the next two decades, a third of humanity will have only half the water required to meet basic needs, said researchers.

I've been listening to a similar argument about oil becoming so scarce that it will be unobtainable in the next X amount of years since I first rode a motorcycle on the road 40 years ago. However with the hiking of prices and the pressure from world powers to get what's left it would seem that thirty years is a bit optimistic imo. To ease the situation we are seeing the hybrid cars hitting the roads and some mixing hydrogen with petrol to make petrol more economical but what's the point when there's nowhere to drive your car? During rush hour it's faster to walk into town if you live within a ... [More]

Oil companies will tells us anything to pacify us as a consumer and that includes food and water. If you have cash I have an investment idea for you and your children bigger than Microsoft. Vertical farming. This technology could make any major city independent of import foods and save water. This can be done anywhere on the planet we just need some backers to make it happen. Not me I'm poor and go to Costco and wall mart. However hear me now this is the future. Vertical farming. I'll add this vid so the UM bot may post it. I hear you but it won't help long term overpopulation... You hear me. ... [More]

I hear you but it won't help long term overpopulation... You hear me. MANAGING PLANET EARTH - MANAGING PLANET EARTH - Experts Scaling Back Their Estimates of World Population Growth - NYTimes.com I do hear you, as a matter of fact governments have been and will be controlling the population. Just look around, no nation that doesn't have oil is getting no aid or help. If your a third world nation with no oil good luck your dead. I have no worries that population control is in full motion as nasty as that sounds. There will be controls my friend.

We already have half the people in the world who do not get the basic necessities of life, and this will get even worse.

We already have half the people in the world who do not get the basic necessities of life, and this will get even worse. The sad part is the more poor you are the more children one has to aid one in your old age. With no retirement plan or health care system children are ones only hope to die a somewhat respectable death with out rotting to death in the street.

Okay mate and I hear you. What narks me is when here in Britain we get half baked ideas by politicians who for instance said words to the effect, We need more people here in order that they can contribute to the pension funds required to keep those who are retired and an increasingly aging population. This when the majority of people born in Britain were (voluntarily?) having less children to cope with sawing prices of most of the necessities of life. The mind boggles. There are controls already natural and otherwise. In my last post I stated that people in poor nations have children to take c... [More]

In my last post I stated that people in poor nations have children to take care of them when they get old due to a poor infrastructure. I see the rich or so called wealthy nations keeping these people poor as more of a problem then helping them. I look at Canada a country that has on average 2 children per family then I look at places not as wealthy having x amount more children. The wealthy need to aid the poor because no one chooses to be poor it just happens. No I'm not a crazy lefty but I see greed as a disease. I smoke and I am forcing all my body parts to accept my addiction and it's not... [More]

Yes I read it mate but imo I think it would be better to give them aid as to birth control and how to manage their life in old age if, as you say, that is why they have so many kids. For one we can look at the Vatican for part of the problem as they say using birth control is against gods will and second a third world nation with poor education believes these religious do gooders under a false pretense. Get rid of bullschit dogma being force feed to the poor and uneducated and we have the beginning of a cure.

You are on the nail with education since the Chinese have already slowed their birthrate and this since industrialization. However there are many who are still poor and ignorant working in the fields etc. The same goes for India to a degree but the way I heard it was ... [More]
