They're a familiar site in gardens and parks up and down the UK, but there are worries that bee numbers are being hit by chemicals used by some farmers.

A group of MPs is calling on the government to ban a number of these pesticides, which are used to protect crops from insects.

Some of the sprays contain chemicals that have been linked to the deaths of bees.

The European Union has called for a ban on these chemicals too.

So far, though, the UK has refused to back the EU ban, saying the impact of pesticides on bees isn't clear.

Bees are really important for the environment, because they help trees and plants to reproduce.

Researchers reckon wild species such as honey bees are responsible for pollinating around a third of the world's crops, helping humans grow enough food to eat.
