  • Extra positive

    You should learn about the genetic bottleneck phenomenon, quite easy to drive extinct. We are deliver actual WWE backbreakers to life everyday. Cheetah’s would be done in short order if they dropped to 0.3%. The Cheetah’s niche may get refilled over time.

    Great positivity for nature’s resilience, but animals and plants are actually quite fragile. We’ve destroyed most of it in not very long compared to the scales you like consider.

    Stay positive, but try to empathize or walk-a-mile in the shoes ... more

    So while I’m giving it three stars, it’s more like a middle point between 5 and 2. James Krellenstein’s episodes are amazing, for example, but many episodes can fall into nuclear advocacy traps, such as excessive hippie punching. Hence, this is a series which can be great, but is very uneven.

  • Well worth the time if you like digging deeply.

    Great guests going into great details of the fascinating topic of (not only) nuclear energy. An absolute must if you are tired of black and white oversimplifications from mainstream content. You learn how old the molten salt idea actually is; under what circumstances EVs help fighting global warming; how to build reactors in time and budget (and how not). Sehr empfehlenswert. Дякую за Вашу працю.

    Ever wonder why a smart guy talks nuclear all day when renewables are the solution? He’s a nuclear industry shill. An oligarch puppet! Shame! Your kids will know you stalled the transition MF!
