Like so many farmers across the UK, Adam Henson is facing a dilemma. In the face of pressure to go green, how can you change your farming habits and still pay the bills? Adam catches up with his neighbor, David Wilson, who is a regenerative farmer, to find out more about one of the big new trends in agriculture and to see what ideas might work on Adam's farm.

Charlotte Smith checks out the soil on both farms and investigates 'greenwashing'. As big companies start buying up land for carbon off-setting, are they putting the UK's food production at risk?

Charlotte Smith visits the Cotswolds to see how Adam is getting on with his experiment in regenerative farming. Adam also meets a robot that could one day eliminate the need for pesticides.

We join Adam Henson on his farm to find out if he is being persuaded to give regenerative farming a go. Charlotte Smith finds out whether a giant grass could help to heat our homes in the future.
