Resumen de Home and dry
Barras reports that around 70% of Earth's surface is ocean, and water makes up 60% of humans' body weight. Few living things can survive for long without water: it's a perfect medium in which organic molecules can dissolve and react to sustain the core processes of life on Earth. But this perfect solution is also a problem. Life's molecules don't just dissolve in water; the electron-rich oxygen of its molecules attacks them, and they begin to fall apart. Living things keep their molecules intact only through clever chemical strategies that perpetually repair the breakages
