Climate change due to global warming and climate disasters such as the Gulf Oil Spill are two catastrophies which imperil the lives of our sea turtles.
In an article titled, Wildlife and Offshore Drilling: The 2010 Gulf of Mexico Disaster: Sea Turtles, Defenders of Wildlife states: "The waters of the Gulf of Mexico and Florida’s Atlantic coast are home to five species of sea turtles: green, hawksbill, leatherback, loggerhead and Kemp’s ridley. All are listed as endangered or threatened under the Endangered Species Act. The oil gushing from BP’s Deepwater Horizon oil rig poses several additional threats to the already precarious existence of these rare creatures."

They further state what the impact of oil is on sea turtles: "Sea turtles are vulnerable to oil exposure at all life stages and through several routes of exposure: contact with skin, ingestion and inhalation of vapors. The exact impact will also vary with the type of petroleum product involved, and by how long it has been in the environment."
Defenders of Wildlife explains more specifically how the oil effects the turtles at certain stages of development: "Oil poured directly on eggs can kill or maim developing turtles, probably because the oil prevents vital oxygen from entering the eggs."
Hatchlings must crawl from the nest to the water potentially crossing a toxic oil zone: "Because they are small, they are more easily overwhelmed by any toxic substance. They are also more likely to choke on clumps of oil and tar, or have their mouths or stomachs blocked... Both sudden exposure to large amounts of oil and longterm exposure to small quantities of oil harm turtles internally and externally."

Sea turtles of all ages have trouble distinguishing oil tar balls from food. If oil is ingested internally, it will effect juveniles and adults by decreasing red blood cells, increasing white blood cells, causes changes in liver enzymes, and can shut down the glands that rid the turtle of excess salt.
"Impacts of oil spills combined with climate change and other oil in the water is not the only problem for sea turtles. The burning of oil and other fossil fuels is a leading contributor to climate change."
"Climate change poses a unique threat to sea turtles, since the temperature at which their eggs incubate determines the sex of the turtle. As global temperatures continue to rise, sea turtles could be faced with the reality of only females being born in clutches that are laid in sand with temperatures over 88.6 degrees F. Sea level rise and storm surge could also destroy sea turtle nesting beaches."

"Beaches are already being lost to erosion caused by development, dredging and chaneling projects. Furthermore, efforts to protect seaside buildings and other structures from sea level rise—particularly beach armoring, shoreline hardening and beach renourishment projects— result in the loss of nesting beaches. Sea turtles also suffer in red tide events, outbreaks of toxic algae that are on the rise due to warming waters. Strandings of sea turtles increase during red tides as the turtles are poisoned by toxins produced by the algae."

"Reasons for Hope: Sea turtles are fortunately one of the better protected animals under various conservation laws. All sea turtles are included in Appendix I of CITES. Six out of seven sea turtle species are protected by the Endangered Species Act."
Defenders of Wildlife is urging strong mandates on the government to prevent future oil disasters and states: "Although we are encouraged by the White House announcement that no new areas will be opened up to drilling until this spill has been fully investigated, Shell has announced plans to move forward with drilling in the Arctic, an area just as ecologically fragile as the Gulf, and where cleanup technology doesn’t even exist" said Jamie Rappaport Clark, executive vice president of Defenders of Wildlife and former director of the U.S. Fish and Wildlife Service.
"It is time for President Obama to reinstate the moratorium on all drilling off of U.S. shores, ensuring that we can deal with the situation at hand without opening another part of our country up to similar disaster. Hopefully this catastrophe will be a wake-up call for Congress to pass comprehensive climate change legislation that moves us beyond drilling along our fragile coastline and towards a cleaner greener energy future."

In a "Defenders Magazine" article, summer 2010, titled Defenders in Action: Defenders Responds to Offshore Oil Disaster, Jamie Rappaport Clark states: "The worst thing about this is that it all could have been avoided. This is not a natural phenomenon caused by Mother Nature. This is caused by people. Something has got to change.”
In July of 2010, Defenders of Wildlife posted information about Obama in an article titled, Obama administration holds threats to America's coasts at bay, issues new offshore oil and gas drilling moratorium. The following is a statement from Rodger Schlickeisen, president and CEO of Defenders of Wildlife: “Today’s action by the administration makes clear that America’s waters and coastlines are too valuable to invite another drilling disaster even before we have stopped the gush of oil from BP’s Deepwater Horizon well. This new moratorium is a welcome and courageous step by the administration, one that demonstrates its commitment to reining in a reckless drilling industry and helping to assure that a tragedy such as the continuing one in the Gulf will not happen again.”
