Will Kemp’s ridleys go extinct?

Kemp’s ridley is the smallest species of sea turtle and has been around for millions of years.  It was around at the time of the dinosaurs!!
Unfortunately, since it exists only in the Gulf of Mexico, it might vanish forever thanks to BP’s carelessness and humankind’s greed in general.
From NYTimes.com:
Federal officials said Tuesday that since April 30, 10 days after the accident on the Deepwater Horizon, they have recorded 156 sea turtle deaths; most of the turtles were Kemp’s ridleys. And though they cannot say for sure that the oil was responsible, the number is far higher than usual for this time of year, the officials said.
The Deepwater Horizon spill menaces a wide variety of marine life, from dolphins to blue crabs. On Tuesday, the National Oceanic and Atmospheric Administration expanded a fishing ban in the gulf because of the spreading oil. But of the endangered marine species that frequent gulf waters, only the Kemp’s ridley relies on the region as its sole breeding ground.
Since the Ixtoc 1 spill, the turtles, whose numbers fell to several hundred in the 1980s, have made a fragile comeback, and there are now at least 8,000 adults, scientists say. But the oil gushing from the well could change that.
The turtles may be more vulnerable than any other large marine animals to the oil spreading through the gulf. An ancient creature driven by instinct, it forages for food along the coast from Louisiana to Florida, in the path of the slick.
It lives its entire life cycle in the gulf, which is why we are so critically concerned,” said Dr. Pat Burchfield, a scientist at the Gladys Porter Zoo in Brownsville, Tex., who has studied the turtle for 38 years.
The Kemp’s ridley is millions of years old; its ancestors once swam with dinosaurs. Sandy olive in color, Kemp’s ridleys are the smallest of the sea turtles, only about two feet across. Although the turtles have been spotted along the Atlantic Seaboard, they return to the warm waters of the gulf to breed.
As recently as the 1940s, they were abundant in the Mexican gulf waters. Tens of thousands at a time would come ashore on the same day at Rancho Nuevo, a remote Mexican beach in Tamaulipas State, to lay their eggs in the synchronized pattern unique to their breed. But pollution, the collection of eggs for food and aphrodisiacs and the nets of shrimp trawlers depleted their numbers.
Then came the blowout on the Ixtoc 1. The deepwater well dumped three million barrels of crude into the gulf, covering the beach at Rancho Nuevo. Nine thousand hatchlings had to be airlifted to nearby beaches. Although the role of the oil in killing the turtles was never confirmed, by 1985, there were fewer than 1,000 Kemp’s ridleys left.
I just happen to love turtles, of any kind, so the possibility of losing a whole species breaks my heart.
