aldelie penguins spend their (austral) winters in the seas surrounding the antarctic pack ice - about 4,000km from their southern spring breeding grounds - where they fatten on krill. the krill feed on phytoplankton beneath the icebergs, but warming waters due to climate change has reduced their numbers by up to 80 percent as the plankton, which are now unable to access cold water nutrients, are dying off.
adelies are the most southern living penguin, but head north as the summer ends to escape the protracted darkness of the winter. a warming climate, however, has meant a reduced northern icepack, and has seen the encroachment of other penguins onto their southern summer territory who previously found it too cold. the adelie population northeast of the ross sea, for example, has declined by 90 percent.
as one adelie expert put it, these penguins face possible extinction not merely by a loss of habitat, but by an unshakable fear of darkness; adelies need light, if only twilight, to forage and navigate, and as comfort against predators. but as they are pushed further south they may ultimately find themselves trapped behind a curtain of polar night for which they have no hardwired strategy.

Brian Skerry photographs the results of commercial bluefin tuna fishing in the mediterranean. The World Wildlife Fund estimates that each year, 4.4 million sharks and 90,000 turtles are unintentionally caught as bycatch from unregulated commercial tuna fisheries using long lines and drift nets. A shark caught in a net will suffocate to death. Shark numbers have declined by as much as 80 per cent worldwide, with a third of all species now threatened by extinction (pew charitable trusts)

native to indonesia and malaysia, orangutans are currently found only in the rainforests of borneo and sumatra. the world wildlife fund lists the borneo orangutan as endangered and her sumatran cousin as severely endangered. the IUCN estimates that in a decade the orangutan will be extinct.
from 1992-2000, the population of the sumatran orangutan declined by more than 50%, with only an estimated 7,000 animals left in the wild, while the bornean orangutan population fell nearly 43% in the past decade, with estimates placing their population between 12,000 and 15,000.
products like shampoo, ice cream, margarine, lipstick, and most processed foods contain palm oil. since more than half the world’s palm oil comes from indonesia - much of it at the expense of orangutan habitat - the cheyenne mountain zoo has created a free app to help you chose orangutan friendly products.
I’m a day late. So what? Every day is orangutan day.
if you don’t spend at least 330 days of the year thinking of orangutan conservation you’re living your life wrong
