The Breath of Trees
We breathe in O2 and breathe out CO2. But trees do the opposite: they breathe in CO2, and breathe out O2. That’s why trees are so important on the planet – we’ve pumped out too much CO2 – because they store carbon in their wood. Kauri trees can store a lot of carbon; they’re the largest rainforest trees in the world.
