The 350 Tree
350.org and Summit Green Build a 350 tree to show what we can do to stop global climate change. The tree was built by Kevin Buckland out of recycled materials, and each leaf, decorated by a child, details one way to reduce CO2 emissions. The tree grew throughout the day to finally include 350 leaves.
