It's the exact position of anyone who studies ecology and conservation. Bees are certainly being killed by pesticides. However, the claim is not about bees. It's about Earth's biodiversity in general. Pesticides are certainly a factor here, but pesticides are not why tuna are overfished, or why elm trees are being wiped out, or why domestic cats are killing songbirds, or why the Amazon rainforest is getting bulldozed, or why polar bears don't have enough ice to hunt seals, etc., etc.
