Group Asks Pope to Declare Sea Turtles 'Meat'
Reuters
Mar 14 2002 2:28PM
LOS ANGELES (Reuters) - A conservation group wants Pope John Paul II
to declare that sea turtles are meat not fish in a bid to cut down on the
illegal practice in parts of Mexico of killing and eating them during Lent.
"The tradition of serving sea turtle ... is largely due to the fact that the
Catholic Church asks its members to abstain from eating meat during
(Lent)," the conservation group Wildcoast said in a statement.
It said some 35,000 sea turtles are killed off the coasts of Baja each year
by poachers, "the highest mortality rate anywhere in the world."
"Many eaters think sea turtle flesh is "fish" because it swims. Wildcoast is
attempting to reach the Vatican to have the Pope declare that the sea
turtle is ... not appropriate to eat during this time," the group said.
U.S. Wildlife officials said they did not see much illegal trafficking of turtle
flesh despite the group's insistence that there is a thriving black market
for it, particularly in Mexico.
The killing of sea turtles has been protected by the U.S. Endangered
Species Act since 1973 and by Mexican law since 1990, the Los Angeles
Times reported Thursday.
Penalties for turtle poaching in Mexico, where the practice of eating sea
turtles during Lent is a longstanding tradition, were raised last month
from three years to a maximum of 12 years in prison, the newspaper
said.
The conservationists believe that the Pope would have a great influence
on discouraging predominantly Catholic Mexicans from eating turtle flesh.
The 40-day period of Lent begins on Ash Wednesday and ends the day
before Easter Sunday.

*Hugs* I shouda asked you first, but I had this sea turtle article and more will appear as Hawaiian Monk seals begin spring whelping and turtles come ashore to lay eggs. I thought we should have it - sad though it is!

Another reason that some people in Mexico may think that it is acceptable to eat turtle during lent is that as reptiles they are cold-blooded. It is the flesh of warm-blooded animals, which includes poultry, which is prohibited on fast days. Hence, you wouldn't be breaking abstaining from meat if you ate snake, or lizard, or even alligator. That is some people's thinking on the subject, anyway.

Pacific Sea Turtles Diving Toward Extinction
SAN FRANCISCO (Reuters) - Giant Pacific leatherback sea turtles are on
a fast track to extinction as commercial fishing and man-made
destruction of their beach nesting areas threaten to wipe out the 150
million-year-old species, scientists said on Tuesday.
Speaking at the Leatherback International Survival Conference in
Monterey, researchers said only a handful of females returned to nesting
beaches along the Pacific coast last season -- down from thousands
who did so just 20 years ago.
The week-long meeting that began Tuesday is aimed at bringing together
marine biologists, environmental activists and fishing industry
representatives to seek ways to ensure the survival of the only sea turtles
without shells.
"The decline is an example of the greatest extinction of a population of
animals that we have probably witnessed since humans have recorded
this sort of thing," James Spotila, a researcher at Philadelphia's Drexel
University told a telephone news conference.
"It is almost as rapid as the extinction of the bison in North America in the
1800s."
Currently there are some 30,000 leatherbacks swimming in the world's
oceans, down from about 115,000 in the 1980s, the researchers said.
The turtles can reach 9 feet in length and weigh 2,000 pounds. The
females come ashore once a year to lay their eggs.
PACIFIC NUMBERS DWINDLING FAST
But the situation of Pacific leatherbacks -- which are genetically distinct
from those in the Atlantic Ocean -- is particularly perilous because their
numbers have sunk to about 3,000 from 91,000 just 20 years ago.
This creates a downward spiral where fewer and fewer females are left to
reproduce, leaving the leatherbacks swimming toward an uncertain
future, scientists said.
For example, last year just 68 of the animals, which spend most of their
time in the water, nested on Costa Rica's most popular leatherback
beach, down from 1,600 only 15 years ago.
More worrying, along Mexico's coast -- once described as the largest and
most important leatherback nesting area in the world -- only 50 females
returned to lay eggs this past season, researchers said.
"The decline in the last five years is nothing short of catastrophic," said
Sylvia Earle, an Explorer in Residence at National Geographic and
leatherback expert. "The number has dropped at a precipitous rate."
Pacific leatherbacks are facing extinction mainly because of commercial
fishing and from commercial development of their nesting areas, the
researchers said.
The main ocean threat comes from longline fishing where a ship can
send out thousands of baited hooks on hundreds of lines that total 60
miles in length, snagging sea turtles, seals and other sea animals, in
addition to the target catch of swordfish and tuna, the scientists said.
BEACH HOTELS A BIG THREAT
Problems on land stem from rapid development of hotels and resorts that
encroach on the beaches where leatherbacks come to lay their eggs, they
added. Egg poaching is also a danger.
But scientists also said there is hope for the sea turtles, so long as
something is done soon. This makes it important to hold conferences
like the one in Monterey where representatives from disparate groups can
search for ways to address the problem, they added.
"Scientists have been talking to each other for a long time," Todd Steiner,
director of Turtle Island Restoration Network, the nonprofit group that put
on the conference. "But it really needs to get into the policy arena."
Some ideas for staving off Pacific leatherback extinction included better
regulating fishing or exploring technology that could scare the turtles
away from the hooks.
Other scientists said solutions were as simple as donating money to
environmental groups looking to buy beaches to hold off development of
hotels and resorts to protect the Pacific leatherbacks' nesting areas.
"If we could just set aside some of these beaches that historically are
critical for the survival this species, we can make a difference," said Frank
Paladino, a biologist at Purdue University. "It is not going to cost billions
of dollars, it is only going to cost a few million dollars."

This is more of a resurrection than an endangered species and very exciting.
Extinct Tasmanian Tiger One Step Closer to Cloning
Reuters
May 28 2002 12:52AM
SYDNEY (Reuters) - Australian scientists announced on Tuesday a
breakthrough in efforts to clone the extinct Tasmanian Tiger, saying they
had replicated some of the animal's genes using DNA extracted from
preserved male and female pups.
The scientists from the Australian Museum in Sydney said they hoped to
clone a Tasmanian Tiger in 10 years if they were successful in
constructing large quantities of all the genes of the Tasmanian Tiger and
sequencing sections of the genome to create a genetic library of
Tasmanian Tiger DNA.
"We are now further ahead than any other project that has attempted
anything remotely similar using extinct DNA," Mike Archer, director of the
Australian Museum, told a news conference.
"What was once nothing more than an impossible dream has just taken
another giant step closer to becoming a biological reality," he said,
adding that the ultimate aim was to clone a viable reproducing population
of Tasmanian Tigers.
The Tasmanian Tiger (thylacine) was a dog-like carnivorous marsupial
with stripes on its back that lived on the southern Australian island state
of Tasmania.
The creature originally roamed Australia and Papua New Guinea, but
sometime between 2,000 and 200 years ago disappeared from the
Australian mainland, only to be found in Tasmania.
It took man only some 70 years to make the Tasmanian Tiger extinct, as
farmers in the 1800s began shooting, poisoning, gassing and trapping
the animal, blaming it for attacking sheep.
The last known Tasmanian Tiger died in 1936 and it was officially
declared extinct in 1986.
COMPLEX OF GUILT
The project to bring the Tasmanian Tiger back from extinction began in
1999 when Australian Museum scientists extracted DNA from an
ethanol-preserved female pup in its collection.
In 2001, further DNA was extracted from two other preserved pups -- the
tissue source for this DNA was bone, tooth, bone marrow and dried
muscle.
Archer said the alcohol-preserved female pup's DNA had given scientists
the Tasmanian Tiger's X chromosome and the other samples the male Y
chromosome.
In May 2002 the museum's scientists, using the extracted DNA, replicated
some of the Tasmanian Tiger's genes using a process called PCR
(Polymerase Chain Reaction).
"The supposedly dead DNA in fact reacts in the way live DNA does.
Clearly the DNA we collected was not extinct -- it works," Archer said. "It
makes molecule cloning possible."
Archer said if the museum was successful it would seek to clone a viable
population of Tasmanian Tigers, using the Tasmanian Devil, another
carnivorous marsupial, as a host.
"We want a viable population. We don't want a strange animal pacing
back and forth in a laboratory. What we want to do is put that animal back
in the wild and for that we need a viable, reproducing population," he said.
But Archer said the technology for the final stage of cloning, putting the
Tasmanian Tiger's genetic material into a Tasmanian Devil host cell
which has been stripped of the devil's genetic material was still to be
developed.
"We don't know the length of this journey. Its up to the speed with which
technology keeps pace with the vision. But I am optimistic," he said.
"The Tasmanian Tiger is an iconic Australian animal, its woven in a
complex web of guilt because Australians made it extinct. We need to lift
this burden of guilt."
