ПЕРЕВЕДИТЕ НОРМАЛЬНО ПОЖАЛУЙСТА )Sweden's Roland Tiensuu, 12, thinks that saving our planet is too important to be left to grown-ups
. Three years ago, the boy learned
from his teacher, Eha Kern (who shares the prize of $60,000 with
Tiensuu), that large areas of rainforests in Latin America had been
destroyed. Tiensuu was worried that by the time he and his class-
mates grew up, there would be no rainforests left to save. "I thought,
there must be something we can do," he says. "I saw a television pro-
gramme where people planted trees to replace some of those that had
been cut down. But of course, we couldn't do that because we lived far
away in Sweden. Then I thought that instead we could buy the rainforest."

With the teacher's help Tiensuu and the rest of the class organized a bake sale in their small village of Fagervik and raised enough
money to buy four hectares of rainforest in Costa Rica. Their school
campaign started the Children's Rainforest, a nonprofit organization whose young members in several thousand Swedish schools have bought 7,000 hectares of jungle with the $1.5

million they have raised so far. Schoolchildren in Germany, Japan and the USA have followed their example. The people of Costa Rica
have named part of the rainforest the Bosque Eterno de los Ninos, or The Children's Eternal Forest.
