Beekeepers in Britain are worried because millions of the honey-makers are dying, and they don't know why.

Bees don't just make honey, they're really important because they play a big part in helping lots of plants, fruit and vegetables grow.

But loads of them are getting ill, and beekeepers are warning they could be wiped out in 10 years.

Newsround's Sonali put on a beekeeping suit, to try and find out more about why bees are under threat.

She discovered that beekeepers know what sort of diseases affect the little creatures, but they don't know why they're getting so many illnesses at the moment.

Bee experts are really worried

They want the Government to spend more money on research to find out what's going on.

Bee expert Robin Dartington said without bees, we wouldn't have a lot of the food we eat.

He said: "It's not only the honey, it's the fact the bees fly out to all the flowers on the plants which we eat for food.

Fave foods

"If they don't go and visit these flowers and pollinate them, then nothing happens later, you get no fruit, you get no seeds.

"Imagine a world in which we could only eat meat, potatoes and bread, not much of a diet, is it?"
