First of all, humans are made of eighteen percent carbon. It is not only found in humans, it is also found in every organism currently known, including plants in a technological way. To plants, carbon flows inside of their cells. They need it to create glucose which then works as food. To humans, it's used in many science sets. It is used in a vast array of compounds including gasoline. Gasoline is what keeps motors around the world running, and it's made up of hydrocarbons with at least 5 carbon atoms each. It also aids the greenhouse effect, keeping the earth warm and habitable by human beings.
