Those children changed their habits and they have started to do something to save our planet :)

These videos tell the story of how the Homestead School of New York helped save endangered rainforests in Costa Rica and Brazil. In 1996, the school built 500 bird houses from scrap wood and sold them to raise funds to adopt 50 acres of threatened rainforest. Through creative fundraising projects, Homestead has helped set aside and protect over 500 acres by raising $100,000 through SaveNature.Org's Adopt an Acre program.
