Captive breeding is the process of breeding endangered animals by capturing them from their natural environment, breeding them in restricted conditions in zoos and other conservation facilities, and releasing them back to the wild when the population stabilizes and the threat to the animal in the wild is lessened or removed.

This technique has been used with great success for many animal species for quite a while, with probably the oldest known such instances of captive breeding being attributed to menageries of European and Asian rulers, a case in point being the Pere David's Deer. The idea was popularized among modern conservationists independently by Peter Scott and Gerald Durrell in the 1950s and 1960s, founders of the Wildfowl and Wetlands Trust and Jersey Zoo - who demonstrated considerable success with a wide variety of life forms in the 1970s ranging from birds (eg. Pink Pigeon), mammals (eg. Pigmy Hog), reptiles (eg. Round Island Boa) and amphibians (eg. Poison arrow frogs). Their ideas were independently validated by the success of Operation Oryx (under the auspices of the Fauna and Flora Preservation Society), which successfully captive bred the Arabian Oryx in 1962 and reintroduced them back into Arabia.

Such techniques are usually difficult to implement for highly mobile species like some migratory birds (eg. cranes) and fishes (eg. Hilsa).

Cars: The road ahead
Thu, 04 Sep 2008 12:30:35 -0000
The world’s carmakers have mapped out their route to a greener futureTHERE is nothing like high oil prices, panic-selling of big cars and the prospect of swingeing new penalties on carbon-spewing vehicles to concentrate the minds of the world’s carmakers. In less than two years something remarkable has happened. Technologies once regarded by horsepower-obsessed marketing departments as politically correct public-relations fluff, never likely to see the light of day, are entering the mainstream just as fast as the car firms can get them there. Only 18 months ago it was common to hear Toyota’s pioneering Prius hybrid joked about as a funny-looking niche vehicle with which Hollywood stars could painlessly flaunt their green credentials. Although General Motors (GM) had exhibited a plug-in hybrid concept car, called the Chevrolet Volt, early in 2007, hardly anyone took seriously the claim that it might reach production in 2010. And just ten months ago carmakers in America were lining up to lobby Congress against proposed legislation that would oblige them to achieve a fleet-average fuel consumption of 35 miles per gallon (mpg) by 2020. It simply could not be done, they wailed. ...
Technology and global warming: The world in a test tube
Thu, 04 Sep 2008 12:30:35 -0000
From plug-ins to planktonic algae, technology is part of the solution to climate change. But which technology?NOTHING about global warming is simple, alas. Meteorological models fry the circuits of the largest supercomputers. Feedback loops and anomalies turbocharge an ill-tempered debate about what will happen where and when. And don’t even start on the politics of negotiating a global agreement on emissions or the intricacies of cap-and-trade. Unfortunately, the technology of climate change is no simpler than anything else. A field that you may think is governed by level-headed, spreadsheet-wielding engineers is alarmingly prone to zealotry and taboos. Climate change is too important and too complex to yield to either. ...
Monsoon floods in India: Bihar's annual sorrow
Thu, 04 Sep 2008 12:30:35 -0000
With some justice, the government gets the blame for a natural disasterAS NEW ORLEANS survived the worst Hurricane Gustav could throw at it, the scale of devastation wrought by another natural fury was becoming horribly apparent. On August 18th the monsoon-swollen river Kosi, a Ganges tributary that flows from Nepal to India, burst an embankment on the Nepali side of the border and flowed into a channel it had abandoned a century earlier. The water gushed into hundreds of villages in the Indian state of Bihar, killing an unknown number and displacing more than 3m, many of whom have been marooned on roofs, trees and tiny islands of dry land. Hundreds of thousands are living in makeshift camps. South Asia’s monsoon rains kill hundreds every year. This summer they have been especially severe, killing nearly 2,000 people in India since June, according to government’s National Disaster Management Division. That total will soon double, at least. Many of the deaths occurred in the north Indian state of Uttar Pradesh. In north-eastern Assam, floodwaters have submerged over a thousand villages and imperilled the state’s rare one-horned rhinoceroses, which have fled a national park for higher ground, putting them within easier reach of poachers. In Bangladesh, flooding has cut off at least 50,000 people. ...
