Of the 1.5-million African Penguin population estimated in 1910, only some 10% remained at the end of the 20th-century. African penguin populations, which breed in Namibia and South Africa, have declined by 95 percent since preindustrial times.
Commercial fisheries have forced these penguins to search for prey farther off shore, as well as making them eat less nutritious prey, since their preferred prey has become scarce. Global climate change is also affecting these penguins' prey abundance. As recently as the mid-twentieth century, penguin eggs were considered a delicacy and were still being collected for sale. Unfortunately, the practice was to smash eggs found a few days prior to gathering, to ensure that only fresh ones were sold. This added to the drastic decline of the penguin population around the Cape coast, a decline which was hastened by the removal of guano from islands for use as fertiliser, eliminating the burrowing material used by penguins. Penguins remain susceptible to pollution of their habitat by petrochemicals from spills, shipwrecks and cleaning of tankers while at sea.
In the year 2000 the total population of African Penguin was estimated to be 200,000 ; ten years later, in 2010, the number was estimated to be only at 55,000. If this decline is not halted, the African Penguin is expected to be extinct within 15 years!
