The article discusses the global decline of insect populations, highlighting the sixth mass extinction event driven by human activities such as deforestation, climate change, and pollution. It reviews the evidence of insect declines, including reduced abundance, biomass, and species richness, and the potential ecological and economic consequences. The article emphasizes the need for more data, particularly from tropical regions, to understand the full extent of the crisis. It also addresses the challenges in assessing insect population trends due to their complex life cycles and the difficulty in identifying species, especially in tropical regions. The article calls for urgent action, including increased funding for monitoring and conservation efforts, and highlights the importance of community science and education in raising awareness and fostering public support for insect conservation.The article discusses the global decline of insect populations, highlighting the sixth mass extinction event driven by human activities such as deforestation, climate change, and pollution.
