Ask yourself this question: How do I interact with the Carbon Cycle?
I live in a house I drive a car I eat food
I wear clothes I breathe I cut my grass
I plant trees
If we want to understand anything about climate change we must learn about the most important atom –

Episode 2
• The most abundant element in living things
• Accounts for 45-50% of the total mass of the biosphere.
• Also present in the Earth’s, atmosphere, soil, oceans, and crust
