Millions years ago much of our earth was covered with blocks (块) of ice. These ice blocks were as tall as high buildings in modern cities. Most of the ice was in the northern (北方的)part of the world.

Then the ice blocks started to move south. Cold and rain came with the ice. Animals and people had to move.

At last, the ice began to melt (融化). After half a million years, most of it had melted. More than half of the earth became covered with water. The climate became much warmer. Things began to grow. The earth began to look the way it looks today.

     Julia Hill, an American woman, was born in 1974． She was 23 years old when she discovered that a company wanted to cut down part of a forest in California. In the forest there were lots of redwood trees. One of the trees was 70 meters tall and 1,000 years old.

       Julia didn’t want the company to do so. She traveled to California and climbed up the tree. “If I sit in the tree,” she said, “the company can’t cut it down.” At the beginning, Julia planned to stay in the tree for two weeks. She lived in a small tree-house and her friends were very helpful-they cooked food for her every day. She used her mobile phone to talk to her family and to the news reporters. She stayed in the tree day and night.

    Environmental organizations supported her, but other people weren’t on her side and they tried to stop her. The company used a helicopter to stay near her tree-house for a long time. The helicopter was very noisy and there was a lot of wind. Julia didn’t like it, but she stayed in the tree.

       In the end, she was successful. The company agreed not to cut down the redwood. Finally, after two years and eight days in the tree, Julia Hill climbed down and walked on the ground again. She and her friends were very happy.
