What was that about every species that becomes extinct being a rivet popping on spaceship earth?

'The apparently rude health of this Welsh puffin population is in marked contrast to the species’ catastrophic decline in what were once thriving colonies on Shetland. The RSPB’s seabird specialist Dr Ellie Owen confirms that on 20 monitored sites across Shetland, the 33,000 puffins counted in the last nationwide census in 2000 have plummeted to just 570 individuals. A Further afield, these auks are also in dire straits: Norway has seen vertiginous crashes, with hundreds of thousands of adult puffins in the once-teeming colony of Røst struggling to fledge any chicks in recent years...

Seabird scientists regard puffins – which in the breeding season are the only species to return to land with fish very visibly held in their beaks, as long as there are fish to be found – very much as coalminers used canaries.'
