Do you ever dream about climbing Mount Everest, which is 8,848 meters high? If so, you're not alone. Every year, thousands of people try to climb the world's highest mountains or walk across deserts. Let's take a look at some of the 21st century's greatest adventurers (冒险家).

    Ed Stafford

    Ed Stafford from the UK is the first person to walk along the Amazon River from the mountains of Peru to the mouth of the river in Brazil. There are many dangerous animals in the rainforest, but he was only bitten by ants and mosquitoes. On his trip, Ed had to find fruit and nuts or catch fish each morning. He used a radio to ask the people of the rainforest for food and help. Many people came to meet him and guide him through the rainforest. While he walked, Ed wrote a blog to tell the world about climate change and destruction (破坏) of the rainforest.

    Gerlinde Kaltenbrunner

    Gerinde Kaltenbrunner from Austria is one of the world's greatest climbers and has climbed all the world's mountains over 8,000 metres. It's very difficult to climb in the cold weather and storms, but Gerlinde loves it. Now she spends her time climbing and helping a charity for poor children in Nepal.

    Meagan Mcgrath

    Some adventurers are always looking for a new challenge. Meagan Mcgrath from Canada has climbed mountains, ridden a bike across Canada and run races in the desert to raise money for the disabled.

    Erik Weihenmayer

    Erik Weihenmayer from the United States has climbed mountains and ridden a bike through deserts. Amazingly, Erik is blind and he wants other blind people to have active lives too. He has taken groups of young blind people climbing in Nepal.
