In the heart of Mexico City, a lone kayaker glides through ancient canals.
Omar Menchaca, 63, is a former mining engineer turned environmental advocate.
For over three decades, he’s paddled through Xochimilco, collecting trash and raising awareness.
A UNESCO World Heritage site, Xochimilco is known for its Aztec-era canals and floating gardens.
But pollution and urban expansion now threaten this fragile ecosystem.
Despite a city-wide plastic ban, bottles and bags still choke the canals.
Menchaca says the wetlands are critical for recharging the aquifers that supply drinking water to millions.
