A project that appealed to me was just posted through Highlights. It sounds like such a simple thing to do, but how much fun will it be to know that students from every part of the globe were doing the very same thing at the same time!
The Green Wave is a tree planting celebration for children and youth around the world. It leads up to the International Year of Biodiversity in 2010. Each year, The Green Wave will contribute to worldwide celebrations of the International Day for Biological Diversity (IBD). It also supports other national, international and global tree planting initiatives such as the UNEP-led Billion Tree Campaign. In participating schools, students plant a locally important tree species in or near their schoolyard. Where possible, the tree should be planted on 22 May IBD. In some countries, it may be too hot, too cold, too rainy, too dry or too something else to plant on 22 May. If such conditions apply to your country, you can plant in another month but still be involved. On 22 May, students around the world will count down to 10:00 local time, when they will water their tree in their respective schoolyards, thereby creating a figurative green wave starting in the far east and traveling west around the world. Throughout the day, students can upload photos and text summaries on The Green Wave website to share their tree-planting story with other children and youth from around the world. The interactive map will be launched at 20:10 local time, thereby creating a second green wave .
Much more information and many ideas for participating in this project can be found at the website http://greenwave.cbd.int/.
Let me know if you do this!
