Carbon farming is being touted as a way to slow down and reverse climate change.
The idea is that you can suck carbon from the atmosphere and store it in plants and the soil, and farmers are being paid to change the way they farm to promote carbon storage.
Some are regrowing native forests on their farms which were cleared generations ago, others are improving their ground cover to make sure carbon stays locked away.
They earn carbon credits which can be bought by polluters to offset their carbon emissions.
I think it's easier to search for a soft answer, something like carbon sequestration rather than tackling the really hard issues of how do we stop emissions in the first place.- Dr Kate Burke founder of Think Agri
But while there are opportunities, there are also concerns. And critics say the amount of carbon farmers can store is limited and difficult to measure.
