There are growing concerns about food insecurity in the developing world. Rising food prices, weather emergencies and political problems are deepening the struggle of families in many countries.

Three United Nations agencies published a report last week before Sunday's World Food Day. This year's \high prices are likely to continue. Gregory Barrow, who works with the World Food Program in Rome, said that if we look at the places where World Food Program works particularly in developing countries, we see populations of people who might be spending sixty, seventy, eighty percent of their salaries

on purchasing food for their families.

The report says even short-term price increases can have a long-term effect. Reducing nutritious food early in a child's life can affect mental and physical development and limit future earnings.

East Africa is suffering its worst drought in years. In Kenya, at least three and a half million people are going hungry, especially in the North.

Farmers say bad roads and a lack of transportation make it difficult for them to get their produce to market. Storage is another problem. And they complain about a big drop in food prices.

People at Kenya said the government should make some arrangements—perhaps even give transport. Then, they can buy food at a good price, then give it to those people instead of asking for food from overseas, which is very bad.

Having reached the top, the thin youth looks down through his black-framed glasses and poses on the edge of the roof like Spider-Man.

\it as a game. Tall buildings are like final monsters in a computer game and I'm the brave player,\said the 21-year-old firmly.

Zhang, from Linyi city of Shandong province, used to climb up to the roof of his house when he was a little boy, which always annoyed his parents. He could go up to the top of houses more quickly than other children of his age. A scar, a reminder of falling from a roof, can be clearly seen below his left eyebrow.

He didn't become serious about scaling buildings without equipment until last September when he posted a photo online showing him atop a residential building.

But instead of people being surprised, as he had expected, most citizens doubted the authentic of the picture and thought he was trying to grab fame. He was puzzled by or even angry with those responses for a couple of days, because he really likes climbing without equipment and just wanted to make friends, who are also interested in it.

He admired the French climber Alain Robert. But he said the French man plans before climbing, but his climbing is at will.

\about most is the freedom of standing in the air,\
