Susan is the daughter of the famous environmental scientist Clark. But the woman has become an environmentalist on her o1．.

In 1992, the first UN Earth Summit(峰会) was held in Rio de Janeiro. Thousands of people from around the world h2． for it to talk about the Earth’s tomorrow. Twelve-year-old Susan and three of her friends formed a group. They raised money to travel to Rio to a3． the summit.

At the summit, Susan said that the state of the environment w4． her a lot. “You don’t know how to fix the holes in our ozone layer (臭氧层). You don’t know how to bring back forests that once g5． where there is now desert. If you don’t know how to fix the Earth, please stop b6． it!” The six-minute speech silenced all the people and made them fall into deep thinking.

After that speech, Susan began to lead “two lives.” On the t7． days, she was a schoolchild. But during her vacations, she s8． internationally about the environment.

Now, nearly 30 years has passed since Susan made her Rio speech. Although many of the world’s environmental problems have only become w9．, Susan does agree that some things are different now. More and more people give voice like Susan because they have realized the importance of the environment.

“Thirty years ago, I was fighting for my tomorrow. Now, I am fighting for the f10． of my sons,” says Susan, now a mother of two, who has kept calling people's attention to climate change.
