Wild bee species at risk of extinction in Europe have more than doubled in the last decade. And that matters more than you might think.

Bees pollinate 75% of the crops we eat, from apples and tomatoes to carrots and raspberries. So if bee populations decline, our food system feels it too. So what’s actually driving the drop in wild bees? BBC climate & science correspondent Georgina Rannard breaks it down for us. We also hear from a beekeeper in Sierra Leone about protecting bees on the ground – and what simple changes could help them thrive closer to home.
