Can the linear become the circular? Michael Londesborough explains Earth’s uniqueness and richness in terms of its „circular“ chemistry by taking us on the journey of a single atom of Carbon. The journey illustrates the „circular“ chemistry of Earth as opposed to the general linearity of entropy and the chemistry of other planets. He explains that the circulatory nature of organic chemistry on earth gives us a wealth of opportunity for innovation, and choice. Our choices will determine our success as a species.
