Insect biodiversity under threat

With around half a million species of insects reported to be at risk of extinction and studies already showing a large decline in abundance, this month Horizon looks at what reduced insect biodiversity means for us – and what we can do about it. We speak to rove beetle expert Dr Alexey Solodovnikov about the services insects provide, from waste disposal and pollination to monitoring climate change and providing information about a new pandemic. We find out how scientists hope to cut the use of pesticides – one of the big culprits for reducing insect diversity – with new ways of pest control. We look at how efforts to boost urban green space in Europe’s cities is impacting insect life and we ask whether people’s attitudes to insects affect conservation efforts.

Parks and green spaces in cities provide health and wellness benefits to human inhabitants, but they’re not necessarily beneficial for other urban dwellers – like insects. Researchers are investigating urban biodiversity with approaches such as ‘bee hotels’ to see how cities can better foster insect life.
