Half of Murres seabird population dies after this happened
How To Protect The Ocean
In this episode of the How to Protect the Ocean podcast, host Andrew Luan discusses the significant decline in the population of common murres, a seabird species in Alaska, which has seen about half of its population die off—approximately 4 million individuals—since the marine heat wave known as "the blob" occurred from 2014 to 2016. The primary reason for this drastic decline is linked to the effects of the heat wave on the marine food web rather than direct thermal stress on the birds themselves. The heat wave caused shifts in the availability of food sources, leading to starvation among...

Orcas vs. Whale Sharks: A New Apex Predator Dynamic
How To Protect The Ocean
In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the fascinating behavior of orcas, particularly their recent predation on whale sharks, the largest fish in the ocean. Orcas, known as apex predators, have been observed hunting whale sharks in the Gulf of California. This behavior was documented in a new study published in the journal Frontiers of Marine Science, which includes video footage and images of the attacks. The orcas target the whale sharks by striking their underbelly and grabbing their pectoral fins, aiming for the nutrient-rich liver,...

One-fifth of migratory species on land, freshwater, and in the ocean are facing the threat of extinction due to two major causes: over-exploitation and habitat destruction. This alarming statistic was revealed in a recent report from the UN Convention on the Conservation of Migratory Species of Wild Animals. Host Andrew Lewin delves into the reasons behind this concerning trend, shedding light on the critical issues impacting these species.
Over-exploitation, particularly in the context of fishing and hunting, poses a significant risk to migratory species. The relentless pursuit of these animals for commercial gain has led to a decline in their populations. Andrew highlights the historical exploitation of whales for their oil, which pushed many species to the brink of extinction. While some populations have shown signs of recovery due to conservation efforts, overfishing remains a prevalent threat to marine species.
Habitat destruction is another key factor driving migratory species towards extinction. As these animals traverse vast distances across different ecosystems, they rely on specific habitats for feeding, breeding, and rest. Disruptions to these habitats, whether through human activities or natural changes, can have devastating consequences for the survival of these species. Andrew emphasizes the importance of identifying and protecting these distinctive areas to ensure the well-being of migratory species.
The impact of climate change further exacerbates the challenges faced by migratory species. Shifts in ocean currents, temperature patterns, and food availability can alter the traditional migration routes of these animals. As they struggle to adapt to changing environmental conditions, the survival of migratory species hangs in the balance. Andrew underscores the need for continued research, conservation efforts, and global cooperation to safeguard these vulnerable populations.
Despite the sobering statistics, Andrew offers a glimmer of hope by highlighting that four-fifths of migratory species are not currently at risk of extinction. This positive outlook serves as a reminder of the progress that can be made through dedicated conservation initiatives. By raising awareness, advocating for sustainable practices, and protecting critical habitats, there is a chance to reverse the trajectory of these at-risk species. The episode's informative and engaging approach encourages listeners to join the conversation and take action to protect the ocean's migratory wildlife.
In this episode of the How to Protect the Ocean podcast, host Andrew Lewin highlights a positive aspect of conservation efforts regarding migratory species. Despite the concerning statistic that one-fifth of migratory species are at risk of extinction, Andrew emphasizes that the majority of these species are not currently facing such threats. This revelation provides a glimmer of hope and optimism for the future of these species and conservation efforts.
Andrew points out that out of the 1,189 species examined in the report, 44% have experienced declining numbers, and 22% could potentially vanish altogether. However, he underscores that this means 56% of the species are not currently at risk of extinction. This majority of migratory species that are not in immediate danger signifies a positive outlook for conservation efforts.
The host's engaging and conversational style conveys the importance of this positive aspect amidst the concerning statistics. By highlighting that the majority of migratory species are faring well, Andrew encourages listeners to view this as a starting point for further conservation actions. He stresses the significance of continuing to work towards protecting these species and their habitats to ensure their long-term survival.
Overall, Andrew Lewin's enthusiastic and knowledgeable presentation of this information instills a sense of hope and motivation in the audience. The positive outlook provided by the fact that the majority of migratory species are not currently at risk of extinction serves as a catalyst for ongoing conservation efforts and reinforces the importance of protecting these vital species for the health of our oceans.
Protecting distinctive areas where migratory species stop for feeding, resting, and protection is crucial to ensuring their survival amidst changing environmental conditions. In the podcast episode, Andrew Lewin emphasizes the importance of these distinctive areas for the survival of migratory species. These areas serve as essential stopovers where these species can find food, rest, and protection from predators during their long journeys.
Lewin highlights the significance of these distinctive areas by discussing the migratory patterns of various species such as whales, sharks, and sea turtles. For example, he mentions how humpback whales travel from Hawaii to the Arctic, covering hundreds of thousands of kilometers and relying on specific stopover points for essential activities like giving birth, feeding, and resting. These areas act as crucial waypoints in the migratory routes of these species, providing them with the resources they need to survive and thrive.
Furthermore, Lewin explains that the protection of these distinctive areas is essential in the face of changing environmental conditions, such as climate change. As temperatures shift and currents alter, the traditional habitats of migratory species may no longer provide the necessary resources for their survival. By safeguarding these stopover points, conservation efforts can help mitigate the impacts of environmental changes on migratory species.
The host's passion for ocean conservation shines through as he underscores the urgency of protecting these distinctive areas. Through personal anecdotes and engaging storytelling, Lewin conveys the message that safeguarding these critical habitats is not only vital for the survival of migratory species but also for maintaining the overall health and balance of marine ecosystems. By raising awareness about the importance of these areas and advocating for their protection, the podcast episode inspires listeners to take action and support conservation initiatives aimed at preserving these essential stopover points for migratory species.
