Recently I read the Human Development Report.I couldn't help thinking about another problem which the world is facing-hunger.According to the report,2,400 people are dying from hunger every day；nearly 13 million in southern Africa will be worried about their food supply because of earthquakes，floods or wars.

　　In a word，hunger remains the biggest problem of the world today.It's strange to see that man can travel to the moon，but still doesn't know how to feed himself.You may ask，"Who steals our bread？" The first thieves should be population growth，poverty and loss of rich farmland.

　　In less developed areas like South Africa，the population grows faster than the crops.It is almost impossible for its government to feed so many people and provide education for them.So it is very important to control the population growth and protect their farmland in countries whose people are suffering from hunger.

　　According to the report，the world's food production is enough to feed everyone if it is given away well.But the problem is that the developed countries are eating food that should be given to the poor.Although they are just using their own earning，the fact is that they are coldly watching others starving away.

　　Luckily，some developed countries such as Netherlands，Norway and Sweden have done a lot to help those hungry people in African countries.We hope other developed countries will follow them.
