In many parts of the world, land that was once forest has changed greatly. Some of the land has become part of cities or towns. Some forest areas have become farmland while some other places no longer have any trees because they've been cut down for other reasons. This causes problems. It affects the climate, causes animals to move or die, and can cause deserts to expand.
在世界上许多地方，曾经是森林的土地发生了巨大的变化。有些土地已成为城市或城镇的一部分。一些林区已经变成了农田，而其他一些地方已经没有树木了，它们由于其他原因被砍伐了。这将导致问题，它影响气候，导致动物迁徙或死亡，并可能导致沙漠扩大。

In Jiangxi Province, 83-year-old Zou Lianying has been planting trees on her land for almost 20 years. She knows that planting trees is good for the environment, so at the age of 64, she sold her cows and pigs and borrowed money to open a forest farm. Her family's forest farm has trees covering about 4 km2 with more than 8 million trees. Her trees are worth around 12 million RMB but she won't cut down even one tree and still lives very simply. She believes the forest she is planting will be a gift to future generations.

Near Beijing, Wei Guiying and a team of helpers have planted millions of trees. They have also been working at this for more than 20 years. Now, 20 km2 of hills have turned green. It hasn't been easy for her. She has borrowed money to pay for seedlings and still owes a lot of money. This doesn't seem to matter to her, though, as she says proudly that she's not a millionaire but she has millions of trees.

A lot of work is still needed to prevent deserts from getting larger and to stop the climate from getting warmer, but if more of us can be like these tree heroes, it will certainly make life better for everyone.
