Bees, soil, trees – even tiny organisms we can’t even see – all play a vital role in producing the world’s food. Yet, this biodiversity, which supports our food and agriculture systems, is under stress.

Speaking to Charlotta Lomas, Dan Leskien, from the Commission on Genetic Resources for Food and Agriculture, explained why biodiversity is essential to food production.
