When the government axed the Sustainable Farming Incentive, many farmers said the loss of cash incentives to grow nature-friendly crops would leave them facing a hard choice.
That choice was between growing as much food as possible to make a profit, or looking after nature while losing money in the process.
But some farmers argue it is possible to do both.
Aidan Stanley raises beef cattle entirely on untouched grass pastures at Lilliput Farm near Bath, a practice which substantially reduces carbon emissions.
"This is working because of public demand," he said.
So what is he doing to make his farm more sustainable, and how does he make it pay?
