Insect Apocalypse: Climate Change Empties Nature Reserves
A decades-long study in Costa Rica’s Guanacaste conservation area reveals a dramatic decline in insect populations, particularly moths, as evidenced by significantly reduced numbers in light trap surveys conducted over the same period and location. This alarming trend, also observed globally, affects even protected areas, suggesting a “new era” of ecological collapse driven by factors beyond localized human impact. Scientists attribute these declines, in part, to climate change disrupting the finely tuned synchronicity of the forest ecosystem, impacting insect life cycles and causing widespread desynchronization among species. The resulting loss of insects has cascading effects throughout the food web, impacting insectivorous birds and other animals, and highlighting climate change as an increasingly dominant force in biodiversity loss.
