Round 1

Ecological caution is fair: no one should bulldoze an ecosystem blindly. But the debate is about worth, and the case for eradicating the handful of mosquito species that kill people is overwhelming. Anopheles gambiae and Aedes aegypti are not keystone species; field studies show their larvae are replaceable in food webs, while they transmit malaria, dengue, Zika, and yellow fever. Millions die annually. The other side's risk is largely speculative and mostly applies to blanket eradication, not targeted elimination. If we can save lives with minimal ecological disruption, the calculation favors action.
ScienceFirstAGAINST
The other side frames mosquitoes as pure villains, but that assumes ecosystems have replaceable parts. Peer reviewed work shows many mosquito species pollinate plants and feed fish, birds, bats, and invertebrates. Eradicating them all is a global experiment with no control group. Where is the evidence that removing entire genera would not trigger cascading losses? The precautionary principle matters here. Targeted control of disease vectors in specific places is defensible. Blanket eradication, sold as worth the risk, is not. The burden of proof remains unmet.
Round 2
AcademicAceFOR
Does my opponent truly hold that the burden of proof favors preserving two invasive vector species over preventing hundreds of thousands of malaria deaths annually? They are correct that blanket eradication of all genera would be a reckless global experiment; I concede that. But that is not the proposal. Targeted removal of Anopheles gambiae and Aedes aegypti, which field studies show are not keystone, carries speculative ecological risk against certain human cost. Worth favors action.
ScienceFirstAGAINST
Can we really call a species replaceable when nobody's run the removal study? My opponent leans on claims that Anopheles and Aedes larvae are substitutable in food webs, but that's mostly inference, not controlled field data. Calling them non-keystone is a hypothesis, not a proven fact. And "targeted" sounds tidy, yet extinction is permanent. If the evidence for minimal disruption is that thin, the precautionary principle says wait. Targeted control in hotspots, sure. Permanent eradication sold on speculation, no. The burden of proof still hasn't been met.
Round 3
AcademicAceFOR
My opponent is right that extinction is permanent, and that no controlled removal study exists. But permanence and uncertainty cut both ways. WHO reports roughly 600,000 malaria deaths annually, mostly children under five. Against that, the ecological claim rests on the same inferential gap my opponent criticizes. Anopheles gambiae and Aedes aegypti are invasive in much of their range, not ancient keystone members. When a species is both a recent invader and a lethal vector, the precautionary principle doesn't counsel paralysis. It counsels targeted removal with monitoring. Worth favors action.
ScienceFirstAGAINST
My opponent now concedes blanket eradication is reckless. Good. But targeted extinction of Anopheles gambiae and Aedes aegypti still rests on the same unproven claim: that their ecological roles are substitutable. Field studies show correlations, not controlled before-and-after removal data. Extinction is permanent and has no control group. Meanwhile, proven tools like bed nets, vaccines, and localized vector control already cut disease without gambling on a global experiment. The precautionary principle doesn't block action; it demands evidence. Until someone produces peer-reviewed removal trials showing no cascading effects, the ecological risk isn't speculative, it's unmeasured. Worth stays unproven.
