Saturday, May 4, 2008　　　　　　　　　　　 Cloudy

Li Ming and I took part in a wilderness survival program yesterday, and it has been one of the most unforgettable experiences since high school.

Early in the morning, we set out. Li Ming was carrying a compass and a tent in his backpack, and in mine there was a flashlight, a map, a knife, a first-aid kit, some matches, candles, food, and clothing.

　　　 On the way to the campsite, we climbed a hill, and then we swam across a river, pushing the backpacks on a large piece of wood we had found by the river.

　　　 As we got into a forest, we lost our way. Luckily, we found the right direction with the compass.

By the time we arrived at the campsite, it had already been dark. Li Ming then put up the tent, and I made a fire and started cooking.

biggest killers in the world contaminated drinking, poor sanitation and air pollution.

Stress the need for equality and fairness in the world. Rich countries have a responsibility towards poor countries and must do what ever they can to help others. Without international cooperation, developing countries cannot prosper, nor will sustainable development b3e possible.
