Is our tecnological manpower keeping pace?
Is our technological manpower keeping pace?
In a recent article of the above title, Prof.R. Rajaraman (The Hindu, December 4, 07, www.thehindu.in) states that the Indian industries are facing a severe shortage of trained manpower and the IT giants alone are hiring several thousand graduates from abroad. This is in spite of the fact that over 2 million Indian graduates are unemployed today. He attributes this state of affairs to the inadequate training our graduates receive in our educational institutions. Undue importance given by the Government to IITs, IIMs and few prestigious research institutions have drained our Universities of funds and needed infrastructure resulting in the low quality of our graduates.

Earth in Heat: 10 Views of a Warming World
The impacts of global warming have begun to appear across the globe, from shrinking glaciers to rising seas.

Climate change has become not only a problem for future generations but a current event that portends catastrophe. The effects of global warming can be seen in retreating glaciers, threatened animals and plants as well as rising seas. Addressing the problem will require humanity to both cut back on the greenhouse gas emissions that warm our world and adapt to a climate that is already in a state of flux, according to the United Nations Intergovernmental Panel on Climate Change.
The need for smart solutions is already evident. It can be seen in the following images, captured largely by photographer Gary Braasch and published in his book Earth Under Fire: How Global Warming Is Changing the World (University of California Press, 2007), which chronicles some of the impacts of climate change around the world:

A one-meter (3.2-foot) rise in sea level, which could result from the melting of a fraction of Greenland's glaciers or Antarctica's ice sheets, would flood 10 percent of Bangladesh, including the village on Bhola Island pictured here, and displace at least 20 million people.

Renewable sources of energy, such as the wind farm pictured here in Rockville, Ill., offer hope of alternatives to the fossil fuels, such as coal, that emit the greenhouse gases, which cause climate change when burned.
