Space vegetables are grown from seeds (种子) that have been taken to space and brought back to the earth. The seeds are affected by the radiation (辐射) and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy.

Here are some facts that you should know about space vegetables.

Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat.

Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes.

For example, if nut genes (坚果基因) are put inside potatoes, people allergic (过敏的) to nuts might get sick from eating these potatoes because they do not know they are also eating nuts.

Dukuly Dogbah, a 14-year-old Liberian(利比亚的) boy, grew up in a war. He was born in the same year the Liberian war started. Since then fighting between the government forces and the rebel armies has not stopped.

Dukuly is one of around 10,000 child soldiers in Liberia. At 10, Dukuly lost contact with his family in the war and had to fight for the rebels. During the war he learnt to kill people with guns. He has killed many people and seen many of his friends die. “You have to," he said, "because it is war."

Lots of children had to join the army. Some did it out of their own will. They thought they would be safe with a gun. The army leaders use child soldiers because they are easy to control and do not get paid much.

Child soldiers do terrible things. Most of them take drugs. “I cannot control myself because it makes me brave," Dukuly said.

Most of the child soldiers are under 18 years of age and the youngest is only 7 years old.
