🔬 Science Environmental Science Resource Management Economic Policy
  1. The use of materials in the U.S. has evolved significantly since 1970, with some materials seeing reduced demand while the economy grows. This shows that it's possible to become more efficient in using resources.
  2. Many materials used today are sourced from other countries, meaning the U.S. is consuming but not producing everything. This raises questions about the sustainability of relying on foreign resources.
  3. As global living standards rise, the demand for materials will increase. It's important to manage these materials wisely to minimize environmental impact while still supporting industrial growth.

The Whale Fall Edition

Why is this interesting? • 1870 implied HN points • 11 Feb 25
🔬 Science Marine Biology Ecosystems Environmental Science Biodiversity Ecology
  1. When a whale dies and sinks to the ocean floor, it becomes a feast for many sea creatures. This event leads to a chaotic but vital ecosystem around the whale carcass.
  2. After larger scavengers eat their fill, bacteria step in to break down the whale's body, turning it into nutrients for other life forms. This process creates a thriving community in a place that usually has little life.
  3. The cycle of life and death in the ocean shows that nothing goes to waste. Even in death, a whale can support new life for decades, reminding us that everything in nature is interconnected.
