The Green Wave is a global biodiversity campaign to educate children and youths about biodiversity. It started in 2007 and leads up to the International Year of Biodiversity in 2010. On May 22, students around the world counted down to 10:00 a.m. local time. At that time, they planted and watered a locally important and indegenous tree species in or near their schoolyard, thereby creating a figurative "green wave" starting in the Far East and traveling west around the world.

In Belize, the tree most commonly planted was the Mahogany tree. The importance of the Mahogany tree to Belize is more significant than that of any other tree to its native country. Our earliest settlement was based on logging. Belize would be a completely different place today if it was not for the abundance of Mahogany trees in the 17th Century. On Friday, May 22, 2009 Programme for Belize was responsible to continue the Green Wave in the Belize River Valley. Omar Gale, Manager of UNDP’s COMPACT pogramme, said, "We have four sites for the Green Wave in Belize. These sites are the Memorial Park in Belize City, Maya Center, Xunantunich and Belize Rural High School."

At the Belize Rural High School, Programme for Belize got eight primary schools from the Belize River Valley to congregate and join the high school in partaking in the Green Wave. These schools are Isabella Bank Primary School, St. Paul’s Bank Primary School, Our Lady Rancho Dolores Primary School, Isabella R.C. School, Double Head Cabbage Anglican Primary School, Burrell Boom Methodist School, St. Thomas Doublehead Cabbage Primary School and Lemonal Primary School. Each school planted one tree at a designated spot on the campus of Belize Rural High.

Photos of the global initiative went up on the web at 20:10 local time on the night of May, 22. They could be viewed on the web at http://greenwave.cbd.int. Wangari Maathai, winner of Nobel Peace Prize in 2004, said, "When we plant trees, we plant the seeds of peace and the seeds of hope."
