Article: You might have noticed that the cost of food has gone up.In fact the price of wheat and rice has nearly doubled in the past few years.It's thought that right now,850 million people--that's more than 10 times the population of the UK--are short of food because it's too expensive or there's not enough of it.

Another reason is climate change.Droughts and floods make it hard to grow crops like rice and grain.The price of oil has gone up and that makes it more expensive for farmers to run their tractors and to transport the food they make.And lots of fields are being used to grow crops to make other things that can't be eaten--which is bad news for hungry people. The main losers are poor people who live in cities in poor countries,who are facing higher prices for food.Some people are doing well out of the food crisis though.Farmers in rich countries like the US,Canada and Australia are getting record prices for their harvests. World leaders are meeting in the Italian capital Rome to talk about the problem of rising food prices.Some countries are helping out with the cost of foods and international aid agencies have called for more money for food production in poor countries.
