     The Amazon rainforest is home to millions of different kinds of animals, plants, and birds. Most of the

world's fresh water is here and the forest plants clean the Earth's air every day.

     Chico was born near the Amazon town, Brazil, in 1944 and started working when he was very young.

Like the rest of his family, the boy got the money by taking a little rubber from the trees in the forest. (The

trees are not hurt when the rubber is taken. ) The forest and its people lived together comfortably and

peacefully.

     But some people think too much about themselves and never think about the future. In 1980, the forest

was burned to build roads, houses and factories. Chico was angry; he wanted to save the forest! He talked to

the government workers, but they didn't listen to him. They were still clearing the rainforests to make quick,

easy money. "Many voices are stronger than one," he thought, so Chico held group meetings. He discovered

that hundreds of people agreed with him. His hope grew. More people came together to try to stop the work

of the forest clearers. Large areas of the forest were saved. Later he traveled to many other countries for

international help. People soon became very much interested in this brave Brazilian. In the next few years

Chico' s name became famous all over the world. The government of Brazil started making plans to protect

large areas of the Amazon rainforest.

     But as Chico's dreams started coming true, someone stopped him in the only possible way. The famous

forest fighter was murdered right outside his home on December 22, 1988. Chico's life was cut short, but his

brave new ideas continued in other people. One man changed the world's ideas. After his death, people around

the world sent money to help Chico's work.
