Mexico wetlands: Conservationists race to protect biodiversity

Summary

The canals of Xochimilco, on the outskirts of Mexico City, represent a diminishing wetland ecosystem that was once rich in biodiversity, including the critically endangered axolotl salamander, unique to this area. Urban sprawl and pollution have led to a drastic decline in axolotl populations, highlighting the fragile state of this ecosystem. Local conservation efforts aim to breed and reintroduce axolotls into their natural habitat, as their survival is intertwined with the cultural identity of the Xochimilco community. The loss of wetlands globally poses a significant threat to countless species, underlining the urgent need for environmental preservation.
