Dozens of grey whales have been found dead along the U.S. West Coast in recent weeks and some scientists believe the cause lies far to the north, in the heated-up Arctic waters off Alaska. Fifty-eight grey whales have been found stranded and dead so far this year in sites stretching from California to Alaska, according to the National Oceanic and Atmospheric Administration (NOAA).
One in five deaths globally are linked to poor diet, experts said on Thursday, warning that overconsumption of sugar, salt and meat was killing millions of people every year. The United Nations estimates that nearly a billion people worldwide are malnourished, while nearly two billion are over-nourished.
