Can soil save us?

GLF Live with Rattan Lal

This episode is now available on Spotify, Apple Podcasts, Stitcher and Amazon Music.

The question – if soil can “save us” from the disastrous climate trajectory we’ve gotten ourselves on – might sound a bit hyperbolic. But consider yourself one step ahead if you stop to give it some thought. While the search continues for all manner of natural and technological ways to sequester carbon released into the atmosphere, we seem to have forgotten just how much can be stored in the ground beneath our feet.

Soil holds an estimated 2,500 gigatons of carbon, which is more than all carbon in the atmosphere and in plants combined – and scientists believe it could sequester billions more tons of carbon annually with the adoption of more sustainable agricultural and land use practices.

From food to water to emissions, the transformative powers of soil – a single tablespoon of which can hold more microbes than all people on Earth – are so abundant that it seems self-evident soil will have a heyday in political and scientific attention. It’s just a matter of when. And so, in this GLF Live, we heard from one of the foremost soil scientists and 2020 World Food Prize recipient Rattan Lal on why soil has gone so long overlooked and how we can start to urgently tap into all the benefits it can bring.
