I think that if Jesus lived in a world that knew what we know now about carbon and plants, he would have said a parable like this:
"The kingdom of heaven is a like a tree, that took what was invisible and made it visible, bringing healing out of decay, giving shelter and food to all within it's canopy, renewing and creating fertility using the cycle of death and new life, taking little, giving everything."
Have you ever planted a tree from seed? If you plant a seed in a pot, where does that tree come from? The soil does not leave the pot, yet, mysteriously a plant appears. Fecundity appears out of nowhere.
How do trees and plants grow? They take carbon from the atmosphere, making lignin and cellulose, and give oxygen in return. Plants take invisible carbon and make it visible in their form and structure. Excess atmospheric carbon creates a blanket of insulation that does not let heat escape. Without woody perennial plants our global ecosystem would cease to function.
Personally, I don't like the coined term 'global warming', but would rather use the term 'climate change'. The climate is changing and is becoming more volatile because of atmospheric carbon. With a growing global population, more food and caloric sustenance will be needed on a huge scale. Annual agriculture is, and has always been, destructive. Tillage is a spark that creates a fire. Fire needs oxygen and carbon to burn. Tillage destroys soil structure and the biological life that keep the whole system going. The byproduct of tillage is CO2. Food systems that are based on trees reverse this destructive carbon emitting cycle. Trees take carbon and store it in their structure and in the ground.
Annual agriculture is selfish, only living in the moment, satisfying it's temporal desires and needs. Planting a tree is one of the most selfless things that we can do. You may never live to see the tree's full potential, but someone after you might enjoy its shade and abundance. We all need to be carbon catchers. Store carbon, plant trees and live well within our global village.
