The Trump Administration has authorized companies to use seismic airgun blasting in the ocean to search for oil.

This practice is highly disruptive and harmful to marine life. It also represents the initial phase of a process that will lead to hazardous offshore drilling, posing significant environmental risks.

Not all "vampires" reside in Transylvania; some infest underwater pens of farmed salmon. Tiny parasites called sea lice make life miserable for both farmed and wild fish, weakening adults and killing juveniles.

These bloodsuckers pose a dual threat: the lice themselves harm fish, and the pesticides used to control them can be toxic to other marine life. Their prevalence signals a critical need for improved practices in certain salmon farms.

Poke, a popular raw tuna dish, raises significant sustainability concerns. Tracking the origin of yellowfin or bigeye tuna used in poke is often difficult, highlighting broader issues in the seafood supply chain.

This lack of transparency is common across the seafood industry, leaving consumers with little information about what they eat. To combat seafood fraud and promote sustainable practices, Oceana is actively working on solutions. Learn more about their efforts: https://bit.ly/2FvJLZo

Southern Resident Orcas, iconic to the Pacific Northwest and frequenting Washington's Salish Sea, face a critical struggle for survival.

This endangered population made national headlines this summer after a newborn calf died, with its mother carrying the body for 17 days in apparent grief. A month later, a young female disappeared and is now presumed dead, further reducing the population to a mere 74 whales.

Efforts to sustainably manage Brazil's gray mullet fishery are underway. This initiative aims to ensure the long-term health and viability of the fishery.

An unexpected benefit of these conservation efforts could be the safeguarding of one of the world's most unusual partnerships, a unique ecological collaboration vital to the region.

Seamounts, or submarine mountains, are vital habitats supporting unique species and migratory animals like tuna and whales.

Historically, these little-studied ecosystems lacked adequate protection. However, this oversight is now beginning to change, leading to increased conservation efforts.

Ghost gear—lost or abandoned fishing nets, lines, and traps—is a silent threat in our oceans.

This derelict equipment continues to entangle and kill marine life, posing a long-term danger even after it's forgotten.

Marine National Monuments in the U.S. face a critical threat. The Trump administration is considering allowing commercial fishing in three of these vital protected areas, potentially weakening their long-standing protections.

We need your help to stop this. Add your name now to tell President Trump not to compromise our Marine National Monuments: https://bit.ly/2PTgTeC

The leatherback sea turtle, the largest living turtle at up to 2,200 pounds, urgently needs our help. These magnificent creatures, along with other at-risk species, face increasing peril.

Recent proposals by the Interior and Commerce Departments aim to fundamentally change Endangered Species Act regulations. If implemented, these changes would significantly weaken vital protections for vulnerable wildlife.

Act now: Tell President Trump not to weaken protections for threatened and endangered species. Sign the petition today.

Marine biologist Patricia Majluf initially focused on studying seals. Following a massive seal die-off, her research expanded to explore the intricate links between seals, fish, and the climate.

Majluf now explains the critical need for changes in Peru's fisheries management. She emphasizes adapting to ever-fiercer and increasingly unpredictable weather and ocean conditions.

Protecting sharks is crucial in the fight against climate change.

Ocean acidification, a dangerous consequence of climate change, occurs when the ocean absorbs excess atmospheric carbon. This carbon reacts with seawater, forming acid.

Acidified water erodes the hard body parts of marine life, including coral, bivalves, and plankton, threatening these vital ecosystems.

Humpback whales are charismatic large whales found globally, from Antarctica to the Arctic, inhabiting both coastal and open ocean waters.

At Talks at Google, Peter Kohler (The Plastic Tide) and Dr. Stefan Leutenegger (Imperial College London) discuss the escalating ocean plastic crisis. They highlight how plastic threatens a vital $5 trillion economic resource and humanity's life support.

The Plastic Tide initiative quantifies this problem using drone imagery and machine learning. Their work involves a vast drone imagery database and a deep-learning algorithm for plastic detection and geo-referenced mapping.

The speakers will present early results, related research, and future strategies to limit ocean plastic. Learn more about their efforts at The Plastic Tide.

The Magnuson-Stevens Act, our vital fisheries management law, faces a significant threat. Proposed congressional changes could prioritize short-term profits, potentially leading to the overexploitation of our oceans. Urge lawmakers to protect this crucial act.

Music for this message was provided by Spearfisher, and the cello performance by Cicely Parnas.

Van Jones presents a compelling social justice case against plastic pollution. He argues that plastic waste disproportionately harms impoverished communities and nations "first and worst," with far-reaching consequences for everyone, regardless of location or income.

In this powerful TEDxGreatPacificGarbagePatch [TEDxGP2] talk, filmed in 2010, Jones offers actionable ideas to reclaim our "throwaway planet." The event was produced by the Plastic Pollution Coalition at the Annenberg Community Beach House in Santa Monica, California.
