Killed, aborted or neglected, at least 100m girls have disappeared—and the number is rising

Mar 4th 2010 | From The Economist print edition

It is no exaggeration to call this gendercide. Women are missing in their millions—aborted, killed, neglected to death. In 1990 an Indian economist, Amartya Sen, put the number at 100m; the toll is higher now. The crumb of comfort is that countries can mitigate the hurt, and that one, South Korea, has shown the worst can be avoided. Others need to learn from it if they are to stop the carnage.

Climate Change = Watertech Boom

Necessity is the mother of invention, and real needs will grow with climate change.

The most fundamental of these is the need for fresh water.

Despite predicted long-term water stress across a wide swathe of agricultural states like California,  we will have to find ways to grow the food we need. All kinds of novel adaptations must be made, from recycling water to learning to grow food in salt water and to reusing water that we do have.

A great deal of California’s energy budget goes to just moving water through the state. Innovation will be needed to reduce this waste of energy.

Discovering or inventing adaptations to the effects of climate change on growing food could make water tech the emerging green boom, especially here in drought-ridden California. The state is getting a third of $58 million in Federal water tech funding designed to stave of hydrological disaster.
