Yes, humans would survive without mosquitoes, but the consequences would be far-reaching and complex, impacting various ecosystems. While the absence of mosquito-borne diseases like malaria, dengue fever, Zika virus, and West Nile virus would dramatically improve human health – "a world without mosquitoes would literally be life-changing and life-saving" – eliminating this species would trigger unforeseen ecological changes.
Impacts on Ecosystems
-
Disrupted Food Webs: Many animals rely on mosquitoes as a food source. Several species of birds, fish, bats, and other insects would lose a significant portion of their diet. The impact would vary depending on the species and its reliance on mosquitoes. "Most species would not starve without mosquitoes, and several would thrive if they disappeared," however, the overall ecological balance would be affected. This would cause a cascade effect throughout the ecosystem, potentially leading to population declines or extinctions in other species.

Altered Plant Life: Mosquito larvae consume algae and other microorganisms in aquatic ecosystems. Their removal could lead to an overgrowth of these organisms, disrupting the balance of these water ecosystems. Conversely, certain plants also depend on mosquitoes for pollination, though this is less significant than their role as a food source for other organisms. [Source: Quora, NICD]

Unexpected Consequences: Removing a species as widespread and abundant as the mosquito from the environment could have cascading effects that are difficult to fully predict. It's crucial to acknowledge that our understanding of intricate ecological relationships remains incomplete. The long-term impact on biodiversity and stability is uncertain.

Human Impact
While eliminating mosquito-borne diseases would significantly reduce human mortality and suffering, it’s vital to recognize that the consequences extend beyond health. The immediate positive impacts of disease reduction could be significant. However, the disruption to ecosystems could lead to indirect effects on human livelihoods, including agriculture and food security.
The Complex Reality
The idea of a mosquito-free world might seem appealing initially, but the reality is far more nuanced. While eliminating the threat of disease is beneficial, the potential ecosystem disruption raises significant concerns. Simply removing mosquitoes without a comprehensive understanding of their ecological role could prove detrimental to overall biodiversity and ecosystem health.
