Agricultural intensification and climate change are driving rapid insect biodiversity loss
In short: A review of documented declines since the end of World War II found that the spread and intensification of agriculture is directly related to massive losses in insect biomass and diversity. Researchers observed that industrial farming practices, such as monoculturing and increased pesticide use, are destroying essential insect populations.
The researchers synthesized evidence showing that the expansion of crops and grazing lands, alongside climate change, is depleting insect biodiversity. This study highlights how the elimination of wildlife habitats and the use of fertilizers and pesticides are destructive to both pollinators and natural pest predators. However, the findings are based on a review of existing documentation rather than a new primary experiment.
Why it matters: Modern industrial farming and a warming planet are significantly reducing the variety and abundance of insects worldwide.
