Discussions about how to reduce greenhouse-gas emissions frequently center on clean energy, more efficient transportation and sustainable agriculture. But research suggests that if we really want to pay attention to our carbon footprints, we should also be focusing on another, less-talked-about issue: the amount of food we waste each day.

The nations of the world agreed years ago to try to limit global warming to a level they hoped would prove somewhat tolerable. But leading climate scientists warned on Tuesday that permitting a warming of that magnitude would actually be quite dangerous.

Cochin International Airport Solar Panels

Day by day, solar power is becoming a more viable source of energy for homes and businesses. If you need further proof of this, look no further than the Cochin International Airport in India that is now entirely powered by solar energy and pays nothing for electricity. The airport last year installed a solar power system with a 12-megawatt peak (MWp) capacity that added to its previous installation that had a capacity of 1.1 MWp, thus giving it enough solar energy to run the entire airport...
