How Pacific winds interact with the sea to bring colder waters up from the depths.
National governments are using political lobbying and empty symbolic efforts to stave off an "in danger" listing for their World Heritage sites.

An infestation as a chick leads to enlarged nostrils in the beak of Darwin finches, and that affects their mating call.
Down House: the home (and garden) of Charles Darwin.
Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.

Blue Planet II reveals what fantastic predators they are.
Life’s not such a beach for Galapagos native species these days.
More than 1,500 introduced species have been recorded on the Galapagos Islands, and most have arrived since the archipelago's tourism industry was expanded in the 1970s.
Trips to Antartica are part of the ‘last chance’ tourism to environmentally fragile places.
No place is off-limits to tourism, so the industry grows without restriction – but there are ways to curb the environmental damage it does.

The Galapagos Islands' giant tortoises are one of the world's best examples of evolution. Scientists are pioneering new conservation strategies to save them from extinction and restore their habitat.
TV audiences cheered on the iguanas' escape, but won't somebody think of the poor snakes?
Visits to Belize’s reefs have been climbing, despite them being listed as World Heritage in Danger since 2009.

Australia's government has lobbied hard to avoid the Great Barrier Reef being described internationally as being in danger. But that publicity wouldn't necessarily hit tourism that hard anyway.
One of the several precious giant tortoises recently found on Volcano Wolf, Galápagos Islands.
When 100-year-old giant tortoise Lonesome George died in 2012, the world thought his species was lost forever. We went to the Galápagos Islands looking for 'extinct' tortoises – and we found them.
The discovery of the genes that influence the beak shape in the famous Galapagos finches highlight the underlying unity of all life.
Darwin's finches are known to be a paragon of evolution by natural selection, but a recent genetic discovery relating to their beaks highlights the evolutionary connectedness of all life.
Darwin’s finch nestlings are highly vulnerable to a parasitic fly – unless their folks fumigate the nest.

When a bird species is threatened by nest parasites, you might think the logical next step is to fumigate – unsurprisingly, though, physically spraying nests (as you might spray an infested house) is disruptive…
Effects of climate change in the Galapagos Islands are threatening one of the world’s rarest seabirds, the flightless cormorant…
