    Kierman was born in Sydney, Australia, and grew up near the sea. For more than 40 years, he raced in international sailing competitions.

    In 1987, Kierman was competing in an around-the-world race when he began to1the huge amount of rubbish in the world's oceans. When he returned to Australia, he2to do something about it.

    He organised a community3called "Clean Up Sydney Harbour". On Sunday, January 8, 1989，more than 40, 000 volunteers came out to4away rubbish. The next year, Kierman made the clean-up a national event. It was a huge5. Across Australia, about 300, 000 people spent the day improving their local6.

    Since then, "Clean Up Australia" has got7every year. In 2002, for example, 800, 000 people cleaned up almost 15, 000 tons of rubbish from Australia's beaches, parks and streets.

    Kierman was8with the success of his project. In 2003, he started an even bigger programme. With the9of the United Nations Environment Programme, he introduced" Clean Up the World ", an international programme that supports communities around the world in cleaning up and protecting the environment. "Clean Up the World" has grown10and his wonderful idea has now spread from one city to the whole world.

The rise of a young scientist

Hannah Herbst, a 15-year-old teenager from Florida, the US, has just become America's Top Young Scientist. She was given this a award(奖赏) for her invention which turns ocean energy into electricity for the developing world.

In fact, Hannah was just a middle school student before that. She came up with this idea because of a letter from Africa. Shortly after the school began in 2014，she received a letter from her 9-year-old penfriend, Rose, in Africa. In the letter, she told Hannah that her family didn't have enough fresh water or electricity. Hannah realised that Rose's situation was bad and in some developing countries some people were in the same situation. She really wanted to help them, so she decided to do something useful.

Hannah began to work on her invention called "BEACON" to produce electricity from ocean power. Luckily, her idea won the attention of Discovery Education 3M Young Scientist Challenge. She got the opportunity to work with a scientist to improve her invention. Thanks to this project, she won a prize of $ 25,000. She offered to donate(捐赠) half of the prize to people in need of energy in developing countries and planned to keep working on BEACON to improve the real life situation.

Bill Goodwyn, the CEO of Discovery Education said, "It is always encouraging to see young people like Hannah use their skills to solve real problems and make changes for the better life of people." Millions of American students have a "scientist dream"，but Hannah was one of the few ones who could realise their goals. She wrote in her blog (博客), "It was so great to see my ideas come to life. I knew that it was hard to begin with, but I kept working and never gave up. After successfully creating BEACON, my love for science was discovered. I hope others will find their interests and make their dreams come true."
