Causa de 3,000 Las muertes de delfines en Perú probable que siga siendo un misterio

Desde mediados de enero, Un estimado 3,000 delfines han sido encontrados muertos a lo largo de las costas del norte de Perú, en lo que se ha convertido en uno de los más grandes mamíferos marinos Dolphin-Perúeventos de mortalidad informaron vez.

Hasta ahora, No se ha determinado la causa, aunque la evidencia de media- y el daño del oído interno, lesiones pulmonares y las burbujas en la sangre son consistentes con impacto acústico y el síndrome de descompresión, dando lugar a la especulación de que la exploración de petróleo en la región puede ser el culpable.

En un comunicado publicado a principios de este mes, BPZ Energy confirmó que se estaba llevando a cabo acústica, Los estudios sísmicos en la zona, pero que las muertes de delfines comenzaron más de 2 semanas antes de la actividad exploratoria se iniciaron.

En la mayoría de los grandes varamientos de mamíferos marinos, no definitive cause is found – in part, because multiple factors are frequently at work. Toxic pollutants, for example, might weaken an animal’s immune system, making it more vulnerable to bacterial or viral infection. Persistent organic pollutants that accumulate in organisms further down the food web also tend to become more concentrated in top predators such as dolphins.

Tar-sand risks threaten health of Puget Sound

The risk from tar sands is too high for local and state agencies to allow these synthetic oils and raw materials increasingly to flow into Washington refineries, say a group of environmentalists concerned about the health of Puget Sound.

LOST in the fight over the Keystone XL pipeline is the reality that we have already seen a steady uptick in the flow of tar sands feed stocks —synthetic oilor the raw material for it — to our five Washington refineries by pipelines or from tankers transiting the Salish Sea. And there are plans on the books for much, much more.

Kinder Morgan — a multinational company also trying to build a coal-export facility on the Columbia River — intends to more than double the capacity of its Trans Mountain pipeline from Alberta to Burrard Inlet in Vancouver, B.C., while deepening its port there to utilize tankers larger than those allowed to enter Washington waters. Should a spill occur, the international boundary in the Strait of Juan de Fuca won’t be much of a barrier to the toxic spread from these larger vessels.

US agency stops seismic energy tests in Gulf out of concern for ailing dolphins during calving

NEW ORLEANS — With sick and dead dolphins turning up along Louisiana’s coast, federal regulators are curbing an oil and natural gas exploration company from doing seismic tests known to disturb marine mammals.

The U.S. Bureau of Ocean Energy Management has told Global Geophysical Services Inc. to not conduct deep-penetration seismic surveys off the Louisiana coast until May when the bottlenose dolphin calving season ends. The agency says the surveys are done with air-guns that can disrupt mother and calf bonding.

The company says it laid off about 30 workers because of the restriction, which it called unnecessary.

Environmental groups are suing BOEM over the use of underwater seismic equipment and say the restrictions should be extended to surveyors across the Gulf of Mexico.

Speak Out for Better Protections for Captive Orcas!

Lolita is a solitary orca who has been confined to a tiny concrete tank at the Miami Seaquarium for more than 40 years. The Endangered Species Act (ESA) provides members of the wild Southern Resident orca population and other endangered animals with a host of protections, including protection against being harmed or harassed. Yet, despite being a member of the Southern Residents, Lolita has been denied all of these protections without any explanation by the National Marine Fisheries Service (NMFS).

The government’s failure to provide Lolita with the protections enjoyed by the wild members of her pod has enabled the Miami Seaquarium to keep her in conditions that violate the Endangered Species Act. Lolita must be granted the protections under federal law which she is rightfully due and which best ensure her survival and well-being, which—depending on her condition—could include transferring her to a sea pen in her home waters and releasing her back to her family pod.

In the wild, orcas live in tight family units with bonds that may last a lifetime. At Seaquarium, Lolita swims endless circles in a small, barren tank that does not comply with USDA regulations. This highly intelligent and social animal has been without an orca companion since 1980.

Sign ALDF’s petition to the National Marine Fisheries Service, urging them to include captive members of Lolita’s Southern Resident pod in ESA protections.
