Scientists say Arctic sea ice has shrunk to its lowest level since satellite records began more than 30 years ago. The director of the US National Snow and Ice Data Center said the Arctic Sea used to be covered by ice that remained for several years, but now it is becoming a seasonal ice cover.

The head of the United Nations food agency has called for coordinated action by the world's richest countries to ease worries about rising food crisis. He said the owners were on the G20 because they produce about 90% of the crops worst affected by price rises. The conference has also urged to help reduce food wastage. Here's Mark Doyle.
联合国粮食机构主席呼吁全世界最富裕国家协作起来缓解人们对粮食危机的担心。他说G20国家是主人,因为最易受粮价上涨影响的作物中,其中有90%的就是这些国家生产的。会议还呼吁减少粮食浪费。Mark Doyle报道。
Delegates to the conference in Sweden were told that about a quarter of the food were produced worldwide never reaches our plates. This increases the prices we pay in the shops and puts unnecessary pressure on land and water supplies. The way food is wasted varies. In richer countries, consumers expect their food to look so perfect that slightly blemished though perfectly nutritious food and vegetables never reach the supermarkets; in poorer developing countries, most of the waste is on farms.
