Female leatherback turtles are among the world's most intrepid creatures, making journeys as far as 10,000 miles after nesting to find food in far-away seas. They've been known to set off from tropical Southeast Asia up to the cold waters of Alaska, where jellyfish are abundant.
But travelling such a long way means encountering threats that can be fatal: fishing nets intended for other species, poachers, pollution and waters warmed by the climate crisis, which force the turtles to travel even further to find their prey.
These turtles are just one of hundreds of migratory species — those that make remarkable journeys each year across land, rivers and oceans — that are facing extinction because of human interference, according to a landmark UN agency report.
Of the 1,189 creatures listed by the Convention on the Conservation of Migratory Species of Wild Animals, or CMS, more than one in five are threatened.

Sustainable construction is moving from ambition to delivery, with whole life carbon, embodied carbon and life cycle cost now shaping decisions on heat, materials and compliance.
New analysis suggests waste-heat networks and large air-source heat pumps could serve 70,000 new social and affordable homes at lower cost than electric panel heating, reducing energy bills by £142m. Record UK Boiler Upgrade Scheme heat-pump vouchers point to rising market confidence in low carbon building systems and energy-efficient buildings, strengthening the case for sustainable building design, low carbon design and net zero carbon buildings as practical infrastructure rather than policy rhetoric.
Circular economy in construction is gaining operational detail through new industry guidance on door reuse, supporting sustainable material specification, resource efficiency in construction and end-of-life reuse in construction.
The shift matters because embodied carbon in materials cannot be cut through cleaner cement alone. Contractors, insurers and regulators will need workable evidence routes for reused components, environmental product declarations (EPDs), lifecycle assessment and whole life carbon assessment if circular construction strategies are to compete with disposal. The priority is a reliable market for low embodied carbon materials, green building products, renewable building materials and low carbon construction materials that can reduce the carbon footprint of construction without creating unmanageable compliance burdens.
The central constraint is execution. Cleaner heat, eco-design for buildings, eco-friendly construction and safer delivery are meeting skills shortages, reskilling demands and post-Building Safety Act compliance pressures. Environmental sustainability in construction now depends on whether procurement teams, installers and building-control bodies can translate sustainable design into dependable, inspectable and affordable systems.
Net zero whole life carbon, BREEAM and BREEAM v7 ambitions will be won through building lifecycle performance, life cycle thinking in construction and carbon footprint reduction across design, specification, construction, operation and reuse. The strongest performers will be those able to make decarbonising the built environment a repeatable construction process, not a project-by-project aspiration.
