Abstract

In any proposal for specicide, as represented by mosquito eradication, one must acknowledge that this involves a complex set of moral trade-offs. Taking it as given that the health burden of vector-borne diseases has to be reduced drastically, this chapter lays out the landscape of normative arguments that can be brought in the mosquito’s defence. These, in turn, should be involved in deliberations about whether such large-scale eradication practices can be morally justified. In favour of mosquito protection, several (but not exhaustive) kinds of arguments are presented based on individual mosquito’s moral standing, the value of each species, concerns about hubris and risks, and questions about preferable alternatives. At the same time, this chapter also inquires whether the conflict between humans and mosquitos can be framed as a matter of self-defence—attributing to humans a right to defend themselves. A morally important distinction here is that the mosquito is merely instrumentalized by the disease that it carries which is the real motive of self-defence, showing that mosquitos are innocent in several senses of the term. Taking all these different moral considerations seriously leaves us with an awareness that the eradication of these species cannot be treated lightly.
