  1. Corona satellites used mid-air film recovery and dual panoramic cameras to capture stereoscopic, high-resolution photos decades before digital imaging, giving a true 3D view of the land.
  2. Those 3D images showed ancient landscapes were more varied and less permanently arid than earlier archaeologists assumed, which challenges the idea that states arose solely to build irrigation in hopeless deserts.
  3. The 1995 declassification and transfer of Corona film to public archives and the USGS opened a priceless historical dataset for scientists to study environmental change and rethink the origins of agriculture.

  1. Cities concentrate health risks: crowded urban living with poor water and sanitation has historically raised infant mortality and infectious disease compared with rural areas.
  2. Grain-based agriculture enabled cities and states but often worsened health: heavy reliance on wheat and other cereals increased cavities, nutritional deficiencies, and stunting, while diets richer in animal foods supported stronger, healthier bodies.
  3. Modern processed-carb diets repeat old mistakes: ultra-processed, calorie-dense but nutrient-poor foods produce an "overfed but undernourished" population, so increasing whole, nutrient-dense animal and plant foods and reducing processed carbohydrates may improve family and child health.

  1. Mergen, now called Nenjiang City, is the main place described and is presented as the largest Chinese settlement the traveler passed through.
  2. The journey had two aims: to find the quickest route between Trans‑Baikal and the Amur and to evaluate commercial opportunities along that route.
  3. The land around Mergen is said to be very fertile black earth, far more suitable for farming than the taiga, and that agricultural richness could have supported a much larger settlement if controlled.

  1. Kelp was once seen as a valuable resource in America for making potash, especially during a time when the country depended on imports from Germany.
  2. Despite initial excitement and plans for kelp processing plants in Puget Sound, they mostly failed to succeed due to stronger competition and external factors like the end of the war.
  3. Other ventures to use kelp, like creating a candy substitute, also did not meet success, showing that not all ideas for using local resources thrive.

  1. In the late 1800s, there was a boom in ostrich farming in America due to high demand for ostrich feathers, which were a luxury accessory for women's fashion.
  2. Ostrich farming proved to be a profitable business, with each ostrich feather fetching up to $5, leading to a surge in ostrich farms and tourist attractions around them.
  3. The domestic ostrich industry saw a revival in the 1980s, but it eventually collapsed due to a speculative bubble, showing the cyclical nature of ostrich farming in America.
