Crested ibises (朱鹮) are one of the oldest bird species (物种) on Earth. It is believed that they have been around for 60 million years. They were once common in Asia. But in the 1960s, they began to disappear because of pollution and other human activities. In 1981, Chinese scientists found seven of them in the wild in Yangxian, Shaanxi Province. They were believed to be the last ones in the world. But now, they have been saved from extinction.
Researchers say its population has risen to more than 5, 000 around the world. There are 3, 000 crested ibises in Yangxian alone. The birds’ survival (幸存) is because of China’s early protection efforts, according to Zhang Yueming, an expert who helps protect the birds in Yangxian.
On the fourth day after finding the ibises, the local government put up a lot of notices to protect the birds. Then, it stopped people from cutting down trees. Later, it set up the Qinling No. 1 protection station and sent four people to look after the birds day and night. During the daytime, they watched and recorded the birds’ habits and conditions. At night, their job was to keep them safe.
To help the ibises have more babies, a rescue and breeding center (救助和繁育中心) was set up in 1990. At the center, crested ibises are fed by people and can receive timely help when they are sick or hurt. China’s protection of crested ibises is an example in the world's history of protecting endangered wildlife.

One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn’t want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?
Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad—and it’s not safe to eat.
If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains (包含) water. This allows mold to easily grow below its surface (表面). Bacteria (细菌) can also grow along with it.
But it’s easy to remove mold from hard food. The mold can’t grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to remove it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.
Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat—and they’re quite delicious as well.
