Water: Life in Every Drop
Format: PDF / Kindle (mobi) / ePub
All known forms of life depend on water. Covering 71 per cent of the Earth's surface, water seems to be plentiful. But there are 1.2 billion people who currently live without a safe water supply, the amount of available drinking water is shrinking and the need for it is increasing relentlessly. While some regions are receiving too much rain, others are receiving too little. We are approaching a global water emergency.
Julian Caldecott examines the vital role this fascinating substance plays on our planet and explores the historical, scientific, political and economic reasons behind the looming water crisis. He reveals where the water we use comes from, and at what social and environmental cost. This is an intriguing and sometimes unsettling portrait of the future of water in our changing world and what we can all do to make a difference.
females, food and water. Territorial aggression between groups would also be anticipated, led by males and aimed at the elimination of outsider males and the control of space and resources. From this point of view, relatively 'soft' aquatic apes, with their gentle and egalitarian ways, would inevitably have become 'harder' on dry land, and this set of influences too would be expected to have left an imprint on our minds. WATER AND THE DIVIDED MIND If we have had both a semi-aquatic and
This way of thinking shows itself in the ideals and social arrangements of military and imperial societies. It feeds into the ways that such societies order themselves into castes and ranks, how they relate to others through war, threat, tribute and terms of trade, and how they train their youngsters, stressing respect for elders and superiors, their place in society and defence of the status quo. It also relates to how they manage their environments, with the wonders of nature valued only to the
part, side or end. They include molecules with a hydrogen-oxygen group at one end (for instance some sugars, like glucose, and alcohols, such as the ethanol in alcoholic drinks), and molecules with a hydrogen, oxygen or nitrogen atom at one end (like water itself, and ammonia, and many biomolecules or parts of them). All of these have a mutual attraction to water, so are called hydrophilic, and the smaller ones all dissolve in water. The same applies to most compounds with ionic bonds, since the
lends to the private sector, and the Multilateral Investment Guarantee Agency or MIGA, which protects private investments. The investment package, worth about US$800 million in total, was finally activated in April 2007, when the Board of Directors of the World Bank Group approved US$130 million in IFC loans, and over US$230 million in guarantees from the IDA and MIGA. During this process, the Bujagali project was challenged by those who held that existing dams on the Nile had contributed to
apart at a distance where the attractive force balances the repulsive force. Desertification. A process usually involving a combination of over-grazing and poor farming practices that expose the soil, drought that weakens it, and wind that blows it away. This destroys plant communities and soils, and degrades the landscape to a point where it looks superficially like a natural desert. DIPECHO.
