Greenland's vast ice sheet, covering 80% of the island and two miles thick, serves as the world's largest natural laboratory. By studying minerals and gases trapped in ice cores, glaciologists unravel ancient mysteries—like past temperatures or the disappearance of the Norse—and gain critical insights into the future of climate change.

Journalist Jon Gertner explores this topic in his book, "The Ice at the End of the World." Purchase it here: https://amzn.to/2RtLtwY

Remanufacturing offers clear benefits, yet remains a niche practice. Our guest will discuss its potential to triple by 2050, enabling better design, material, and energy choices for the future.

The show will also explore criticisms of conventional economic growth. Our guest argues we should stop trying to enlarge the economy, and instead learn to "make ourselves at home with this wealth." This involves considering implementation, ensuring inclusivity, and convincing policymakers.

Mohammed's talk emphasizes the urgent need to reframe environmental education. He advocates for curriculum changes, incorporating topics like lake studies and hazardous substances, and encouraging reflection on future environmental roles. He stresses that we can no longer afford past resource consumption and carbon footprints.

A lifelong teacher, administrator, and enthusiast of molecular and conservation biology, Mohammed developed a love for nature early in Eastern India. Now at UWC Changshu China, he enhances his knowledge in educational leadership and biology. He is passionate about sharing his insights on environmental education's effectiveness and importance with younger generations. This talk was delivered at an independently organized TEDx event.

The Great Australian Bight, a pristine wilderness and one of the world's last unexploited areas, is a vital treasure. It hosts thriving coastal communities, whale sanctuaries, and more unique marine life than the Great Barrier Reef.

However, this incredible ecosystem faces severe threats from dangerous and experimental oil drilling and seismic blasting.

It's crucial for all who care about our climate, oceans, and way of life to protect our Southern coastline. Join us in making oil history: act.gp/makeoilhistory

Treaties between tribes and the federal government, particularly concerning resource use and environmental conservation, have long been a source of legal contention. Their exact status and attendant rights generate significant tension, especially regarding state obligations.

Recently, an equally divided Supreme Court affirmed states' duty to manage resources consistent with tribal treaty rights. This ruling impacts states like Washington, which has resisted requirements from the Stevens' treaties, affirming tribal salmon fishing rights. The critical question remains: what additional state obligations ensure resource sustainability, especially amidst climate disruption? Consistent enforcement benefits all, illuminating the state's trust duties to its people.

Lil' Jawz is an embryonic catshark, developing within an egg case attached to a coral colony. Its yolk sac provides all necessary nutrients, acting as a vital power source for growth and survival

Lil' Jawz is an embryonic catshark, developing within an egg case attached to a coral colony. Its yolk sac provides all necessary nutrients, acting as a vital power source for growth and survival until it emerges into the open ocean.

As an oviparous species, this shark lays eggs externally with no parental care. To support wildlife conservation, join the Center for Biological Diversity's e-list: https://bit.ly/2qE6gBz. Footage courtesy of NOAA.
