Humanity is conducting a giant chemistry experiment with Earth’s atmosphere and oceans, but is it really unprecedented? Justin Rowlatt tells the story of how our planet was made.
Humanity is conducting a giant chemistry experiment with our planet’s atmosphere and oceans, filling them with unprecedented amounts of nitrogen, phosphorus, and above all carbon dioxide.
