It may surprise people to learn that one elephant is killed every 15 minutes for its ivory.

All I want to say is that life is very fragile. We should live every moment and cherish what we have been given.

As the Ambassador for WWF Earth Hour, I still vividly remember that there were only 80 buildings in China that participated the Earth Hour in its first year. Six years later, there were 170 cities and thousands of buildings that participated. We are still growing strong. I am encouraged by the accomplishments we have made together and they make me proud and more determined than ever.

I used to think hard work made me come alive, honestly. I used to have a daily work schedule with millions of things on it and I thought, "This is wonderful!"

Take charity work for example; the motivation of my various charitable activities is neither for fame nor profits. It is my sincere wish that, through my efforts, more people can realize how important it is to protect our planet and to start to act for a change.

Air pollution is my biggest concern right now. Maybe because I live in Beijing, and in this city we have such severe challenges due to bad air quality. It has affected our daily lives and health. I do not go outdoors because of it. I desperately hope that we can improve the current situation.

I only started to understand the concept of "environmental protection" 14 years ago. I was an ambassador for a charity event, and the staff told me that the consumption of disposable chopsticks in China, per year, could result in the devastation of unimaginable acres of forest.
