With increasing fervor since the 1980s, sustainability has been the watchword of scientists, environmental activists, and indeed all those concerned about the complex, fragile systems on the sphere we inhabit. It has shaped debates about business, design, and our lifestyles.
World's children cannot wait any longer. While international community debates and issues recommendations, statements and fine speeches, world's children - marginalised, socially excluded, poor and vulnerable - continue to suffer.
During the Cold War, America took sides not only in disputes between Arab countries, but also in debates within them.
I don't like the whole 'slander, slander' conversation that most political debates are these days. So I tend to keep my political standpoint not to myself, but just relatively private.
Before the Internet, we were in a different sort of dark age. We had to wait to hear news on TV at night or in print the next day. We had to go to record stores to find new music. Cocktail party debates couldn't be settled on the spot.
When I start getting embroiled in heated debates and feeling stressed, I just turn everything off and disconnect from the world. I simply tell my colleagues and friends that I am not well and need to cancel all meetings for a day or more. I take it easy - go for a long hike, take a vacation somewhere, or just stay at home and read.
I like to think I've changed the centre of gravity on lots of national debates.
