Tubbat and his wife, Tosontsagaan, are villagers in Inner Mongolia's Ejin Horo Banner (内蒙古), where there is the Badain Jaran Desert (巴丹吉林沙漠), one of China's four biggest deserts. They have spent many years fighting against the desert. They plant trees in the desert area to keep the sand and protect the environment.

Tubbat has planted more than 50,000 trees covering about the size of 133 football fields. "When I was a child, there were lakes, forests and animals. And it rained a lot," said Tubbat. " But sandstorms turned the green land into a desert. "

Tubbat started to plant trees in 2002 after he finished his job as a government official. His wife supported his decision. They did all this for free and even spent most of their own money. "Many people do not understand why I do this. They don't know the happiness I feel when I see the land turn green again," said Tubbat. "My wife's support gives me energy. Our children want us to live in a city. But this is not the right time. I want to grow more trees," he said.

Tubbat is happy that more people have begun to plant trees after hearing his story. Some have even visited him to learn how to plant trees in the desert. "Trees can bring rain and animals," he said. "I want to be a tree, to grow up in the desert and hold the sand until I die. "

Our earth is in trouble. Our drinking water is becoming dirtier, and the air is not as clean as before! People and factories are polluting the air, rivers and lakes and seas. You may think that there is nothing you can do to help. That's not true. There are many things you can do to help the earth.

Cars burn gasoline. This will produce a lot of CO2 into the air. Some people believe that too much CO2 is making the earth warmer than ever. They think CO2 thins the clouds above us. The clouds keep us away from the strongest sunlight. So try to walk, ride a bike or take a bus. And if you drive a car, drive at a steady speed. This can save some gasoline.

The biggest energy use at home is for keeping cold or hot. So turn the air conditioner off when you don't need to use it. What's more, some people use plenty of water to wash things. It is necessary to save water by reusing it. For example, after washing vegetables, you can use the water to water the flowers. In addition, taking a shower instead of a bath also helps us to reduce the water use.
