For years, ecologists and citizens have denounced the periodic die-offs of marine life in the lagoon due to the runoff of fertilizers from nearby farms.
In 2019, over 50,000 people marched in the nearby city of Cartagena to denounce the degradation of the lagoon. This month, Spain's government approved 20 million euros ($19.7 million) in aid to improve water treatment in towns near the Mar Menor as part of a recovery plan for the lagoon.
"So that natural disasters like those that have occurred, so that the episodes of mortality of fauna of the Mar Menor don't return, let's give this ecosystem its own rights," Senator María Moreno said before the vote.
The law codifies the lagoon's right "to exist as an ecosystem and to evolve naturally" and recognizes its right to protection, conservation and restoration.
In 2017, New Zealand passed a groundbreaking law granting personhood status to the Whanganui River.
