Why aren't we talking about soil?

16 July 2012

A handful of soil contains a billion organisms and more DNA than in a human body. The Earth's soil contains more carbon than the atmosphere and more water than all the lakes and rivers. As Da Vinci pointed out 500 years ago, we know more about the cosmos than the soil beneath our feet. While climate change, ocean acidification and biodiversity loss dominate news headlines, the topic of soil security rarely rates a mention.

The integral role played by soil in the health of ecosystems and human populations should be reason enough for all of us to understand this issue and its complexity. This event was a rare chance to see the world's experts in soil science and security sharing a stage and presenting their latest research along with real world implications.
