Better with Forests
Why do we need forests?

Trees are the longest living organisms on Earth
California holds the record for the oldest living trees. Some of the state’s bristlecone pines and giant sequoias are 4,000-5,000 years old. Methuselah, an estimated 4,852-year-old ancient Bristlecone Pine, is one of the oldest living trees in the world.
Some trees have been to the moon.
“Moon trees'' were grown from seeds taken to the moon during the Apollo 14 mission in early 1971. NASA and the US Forest Service wanted to see if the moon’s orbit caused the seeds to grow differently back on earth. These trees were donated to state forestry services in 1975 and 1976.
Trees are able to communicate and defend themselves against attacking insects.
Scientists have found that trees can flood their leaves with chemicals called phenolics when the insects begin their raid. They can also signal danger to other trees so they can start their own defense. Willow trees, for example, emit certain chemicals when they’re attacked by webworms. Other willows then produce more tannin, making their leaves harder for the pests to digest.
