    1. Explorers, amateurscientists, and early ethnologists like William Byrd all assumed—andunabashedly professed—that inferior or mismanaged lands bred inferior,ungovernable people.

      Assumptions of the 1700s America

    2. Slavery was thus a logicaloutgrowth of the colonial class system imagined by Hakluyt. It emergedfrom three interrelated phenomena: harsh labor conditions, the treatment ofindentures as commodities, and, most of all, the deliberate choice to breedchildren so that they should become an exploitable pool of workers.

      While there is a strong thread of hierarchical male domination over women and their bodies, is some of the anti-abortion movement in the 21st century an historical appendage or outgrowth of "breeding children" as an exploitable pool of workers for capitalists?

    1. Zusammenfassender Artikel über Studien zu Klimafolgen in der Antarktis und zu dafür relevanten Ereignissen. 2023 sind Entwicklungen sichtbar geworden, die erst für wesentlich später in diesem Jahrhundert erwartet worden waren. Der enorme und möglicherweise dauerhafte Verlust an Merreis ist dafür genauso relevant wie die zunehmende Instabilität des westantarktischen und möglicherweise inzwischen auch des ostantarktischen Eisschilds. https://www.theguardian.com/world/2023/dec/31/red-alert-in-antarctica-the-year-rapid-dramatic-change-hit-climate-scientists-like-a-punch-in-the-guts

    1. frost heave
      Before the understanding of frost heave, there was a widely held belief that rocks and stones could grow and multiply. Stones were believe to grow from small pebbles. These stones then rose to the surface of the ground. Another belief was that stones were the offspring of “mother-stones” or “breeding-stones.” Today, it is known that this motion of stones moving upwards toward the surface of the ground is due to frost heave. Frost heave occurs when water in soil or rock freezes and thaws in a cyclic process. This causes an upward movement of the surface of the ground due to the freezing of water underneath. Geologist Stephen Taber from the University of South Carolina proved through extensive research that “it was not expansion, but rather the formation of ice lenses by segregation of water from the soil as the ground freezes that is the principal cause of frost heave.” He also showed that liquids other than water can also cause frost heave. The direction of heave is governed by the growth of ice lenses. Ice lenses form perpendicular to the direction of heat flow, so it is not always the case that frost heave occurs in the path of least resistance (Manz, 2011).
