Insects and Humans at Mutual Risk?

Experts have claimed that, if the insect losses continue, things will become very difficult for humans (https://www.theguardian.com/environment/2020/feb/20/fates-humans-insects-intertwined-scientists-population-collapse). They suggest that, although it is often unclear what precisely is going wrong for each of the declining 6-legged species, there are some obvious things that can be done.  We could greatly increase the sizes of reserves (with a reduced focus on bird and mammal species); reduce the spraying of harmful chemicals; cut our lawns less frequently and leave dead wood in our gardens. Insects are a very necessary part of terrestrial ecosystems.
