United Nations Secretary-General Antonio Guterres has expressed concern over the global food situation wherein "more than 820 million people do not have enough to eat" while one billion tonnes of food is wasted every year.
In his message on 'World Food Day', which was released here on Thursday by the UN India, he said, "It is unacceptable that hunger is on the rise at a time when the world wastes more than one billion tonnes of food every year."
