Pandas are in danger. There are only about1, 600 pandas in the wild today. Zoos and research centers are looking after about 340 pandas. Pandas do not have many babies, and baby pandas often die. The situation is getting very difficult. Scientists are doing a lot of research to help pandas produce more babies and help baby pandas live.
Pandas live in the forests and mountains of Southwest China. Each panda needs to eat a lot of bamboo every day. The bamboo forests are getting smaller, so pandas are losing their home.
In order to protect pandas in the wild, the government is setting up nature parks and developing other plans. The nature parks will be big and there will be more bamboo to feed the pandas. Pandas born in zoos may go back to live in the nature parks.
The World Wide Fund for Nature(WWF) wants to protect all animals. And it chose the panda to be its symbol. We do not want to lose tigers, elephants or any other animals, so the WWF is working hard to save them all.

This week is our school's Water Saving Week. Water is important to us. All living things need water. Without water, there would be no life on earth. 75% of the earth is ocean, but the sea water is salty. The drinking water on Earth is very limited. Fresh water is becoming scarce because of factory wastewater and domestic sewage. There are still some people wasting water.
Then what should we do to save water We should start with small things and make good use of each drop of water. And we should try to protect water resources and never pollute lakes or rivers. It's not easy to save water. So we should do our best.
Let's save water together!
