The Earth’s entomofauna seems in an ongoing state of collapse. Insect decline could pose a global risk to key insect-mediated ecosystem functions and services such as soil and freshwater functions (nutrient cycling, soil formation, decomposition, and water purification), biological pest control, pollination services and food web support that all are critical to ecosystem functioning, human health and human survival. At present the attention for insect decline is low in all domains, ranging from scientific research to policy-making to nature conservation. Scientists made urgent calls to prioritise insect conservation. An international treaty for global pollinator stewardship and pollinator ecosystem restoration is urgently needed to counteract the current crisis. A review of insect pollinator conservation policies found that despite scientific calls and public outcry to develop polices that addresses declines, governments have not delivered such legislation, nor have they met basic monitoring needs recommended by experts.
