To make the circular economy work, organisations need to purchase products that have been made from recycled materials. But many materials, especially when they have been contaminated, cannot be recycled. They face a gradual downward slope ending in heat death incineration. It’s about increasing entropy – that is to say, disorder. For which, read usefulness. There’s only so many times paper and plastic can be recycled. There’s only one principle in existence on planet Earth that reverses entropy, creating order from chaos, usefulness from dust – and that is life. Life’s organising principle, from the cell, through organisms, ecosystems, and up to the ecosystem of the entire planet, is what gives us life and our life support system.
