This article examines the causes of insect extinctions, such as overexploitation, climate change, and pollution, and its impacts, such as loss of biomass and biodiversity. The following is an excerpt from the abstract:

“Here we build on the manifesto ‘World Scientists’ Warning to Humanity, issued by the Alliance of World Scientists. As a group of conservation biologists deeply concerned about the decline of insect populations, we here review what we know about the drivers of insect extinctions, their consequences, and how extinctions can negatively impact humanity.”
