Christine Figgener – My Life With Sea Turtles

Christine Figgener, a world-renowned marine biologist, discusses her passion for sea turtles and the importance of their conservation. She shares her journey to Costa Rica and her first impressions of the research station. Christine explains that there are seven extant species of sea turtles, each with unique characteristics and diets. She emphasizes the role of sea turtles in maintaining the underwater ecology, such as the green turtle's grazing on seagrass and the hawksbill turtle's role in controlling sponge populations on coral reefs. Christine also touches on the declining numbers of sea turtles and the potential impact on the underwater ecosystem. Sea turtles play a crucial role in maintaining the health of our oceans. They are considered keystone species that help regulate the ecosystem. The green turtles keep seagrass matters in check, while hawksbill turtles control sponge growth on coral reefs. Sea turtles also contribute to the provision of food by feeding on jellyfish, which helps maintain the balance of larval fish populations. However, sea turtles face numerous threats, including climate change, habitat destruction, and illegal harvesting. The mating and nesting behaviors of sea turtles are still not fully understood, but efforts are being made to study and protect these processes. Volunteerism in sea turtle conservation can be both positive and negative, with some organizations exploiting volunteers for profit. The viral video of a sea turtle with a plastic straw stuck in its nose brought global attention to the issue of plastic pollution and the need for change. Despite the challenges, there is hope for the future of sea turtles, as they have shown resilience and the ability to recover if we make positive changes to protect their habitats and reduce threats.

Nadina Galle – The Nature of Our Cities

The conversation covers various topics related to urban ecology and the importance of nature in cities. It touches on personal experiences, the role of technology in enhancing urban greenery, and the challenges faced by urban foresters. The guests discuss the need for better data collection and mapping of trees, as well as the importance of community engagement and policy changes to protect and enhance urban nature. In this conversation, Nadina Galle discusses the importance of preserving trees on private land and the challenges of implementing tree ordinances. She also highlights the efforts of Matt Wells in Santa Monica to increase canopy cover and advocate for a private tree ordinance. The conversation then shifts to the role of technology in urban forestry, including the use of high-resolution satellite imagery to map trees on private land and the development of the Burnbot firefighting robot. The discussion also touches on the impact of climate change, the importance of nature in cities, and the use of technology to engage people with urban nature through apps and immersive experiences. The conversation concludes with a reflection on the potential benefits of a daily dose of nature and the importance of reconnecting with the natural world.
