Biodiversity loss increases human biting

Loss of vertebrate diversity can force generalist mosquito species to shift blood‑meal composition toward humans, increasing human‑vector contact rates even without mosquitoes 'preferring' humans biologically. Molecular gut‑content studies in disturbed habitats (e.g., Brazil’s Atlantic Forest) can reveal rapid dietary shifts that raise spillover risk. — If widespread, this mechanism links habitat conversion directly to higher zoonotic and vector‑borne disease risk, implying land‑use, conservation and public‑health policy must be coordinated to prevent emergent outbreaks.
