Why the zebra mussel is illegal but mass migration is not
While the zebra mussel triggers hundreds of pages of guidelines and sanctions, the economic impact of migration is barely analysed. An ecological double standard that spares no one.

Why the zebra mussel is illegal but migration is not: the double standard nobody wants to see
Why can a foreign mollusc trigger a legal apparatus running to hundreds of pages, while the movement of people across borders generates barely any comparable economic analysis? The question is not new, but it resurfaces every so often, usually wrapped in labels that distract from the substance: the discrepancy between how we treat biological and human intrusions.
Government ministries publish exhaustive guides on invasive species. The zebra mussel, the red fire ant, the tree of heaven and the water hyacinth each have their own sanctioning regime and multi-million-euro eradication plans. The ecological logic is clear: they alter ecosystems, displace native species and cause substantial economic costs. Yet when the impact of mass migration on public services, the labour market or social cohesion is raised, the debate becomes judicialised and official figures are scarce.
Spain's Official State Gazette (BOE) sets out precisely which species may not enter or be bred in the country. But for people the framework is different: human rights, international conventions and integration policies. Economics, however, recognises no sarracena exceptions: any massive influx of new agents — whether molluscs or humans — affects the housing stock, wage pressure and public spending. Studies on the fiscal impact of immigration do exist, but never with the firmness of a royal decree on exotic species.
Herein lies the contradiction: a mussel clogging pipes mobilises three ministries; a mass arrival straining hospital waiting lists barely merits an economic impact report. While environmental regulation is enforced with a firm hand, the economic analysis of migration drifts between ideology and taboo.
The difference, of course, is that a mollusc cannot vote. But that is a reflection that goes beyond economics and enters the realm of politics. And politics, like ministerial guidelines, tends to choose which imbalances deserve to be measured.
