Summary:
- The European Union banned the use of certain pesticides that were harmful to bees, and this has led to a recovery in bird populations.
- Birds that feed on insects, like sparrows and swallows, have seen their numbers increase since the pesticide ban, as the insects they rely on for food have become more abundant.
- This shows that reducing the use of harmful pesticides can have a positive impact on the broader ecosystem, benefiting both insects and the animals that depend on them.
