Yao Ming was born in Shanghai in 1980. At 229 centimeters, he was the third tallest player in NBA history. Yao made his first appearance in the NBA during the 2000 Sydney Olympics. He surprised many critics with his first games, and was fast becoming an international fan favorite, as he broke Michael Jordan’s record for votes (投票) received. In July 2011 Yao announced his retirement from the NBA due to frequent problems in his left foot.

He continuously works to raise awareness of endangered species and even went as far as to stop using shark fin soup at his wedding in 2007. Yao has been saying no to shark fin soup since 2006 when he was appointed Goodwill Ambassador (亲善大使) for wildlife protection. “Shark’s are friends of human beings. They are not our food.” Since his retirement he has become a surprise international force in the field of wildlife protection, and he is using his fame to tell us the difficulties faced by sharks.

Most recently he went to Houston Zoo, as part of his continuing effort to educate young people about the importance of wildlife protection. He is part of a large campaign (运动) by the wildlife protection charity WildAid, and has traveled through Africa to see and document the difficulties facing elephants and rhinos in the wild. With elephant and rhinoceros poaching (偷猎) on the rise, Yao also said, “When the buying stops, the killing can too. Get rid of the demand for rhino horn and ivory right at the source. That’s what I want to do.”

Although Yao is not the first Chinese player in the NBA, it could be argued that he is the most important one, not just for his taking part in charity and wildlife protection work. He built a bridge between two completely different worlds and introduced millions to the Chinese way of life, and the American lifestyle separately.

The number of giraffes is becoming smaller across Africa, according to the Giraffe Conservation Foundation. The total population has dropped by 40 percent in the last 15 years. People care little about it. Surprisingly, even scientists haven't given much attention to giraffes. "We are learning more about their ecology, but what we know is still way behind what we know about other species. It's a silent extinction (濒临灭绝)", said Dr. Julian Hennessy, a wildlife scientist.

"The main reason for the smaller number of giraffes is their loss of living places," said Hennessy, "as an increasing part of land is used for farming. But hunting also has a big influence." You might wonder why hunters like giraffes. First of all, once a giraffe is brought down, there is lots of meat with a small amount of effort. Besides, there is another thing encouraging the hunting. In Tanzania, Hennessy says, the latest word on the street is that eating giraffe meat could cure AIDS. Fresh giraffe heads and bones can be sold at prices of up to $140 per piece.

Another widespread misconception about giraffes is that they are everywhere. Look at kids' books which are full of giraffes. They are always in zoo collections. They can be seen easily, so you don't think we have to worry about them. But the truth is that they are in danger of extinction. There is a lack of right and true data.

Hennessy and other researchers are now pulling together the data needed to improve the situation of the entire giraffe species. He hopes that the world will finally start to realize how endangered these beloved animals have become.
