Historia
Michael Pollan, known for his best-selling nonfiction audio, including The Omnivores Dilemma and How to Change Your Mind, conceived and wrote Caffeine: How Caffeine Created the Modern World as an Audible Original. In this controversial and exciting listen, Pollan explores caffeine’s power as the most-used drug in the world - and the only one we give to children (in soda pop) as a treat.

Informative and not too long
Revisado: 01-10-25
Well written, informative, to the point. The author could have gone to much more content but kept the story line around his personal experience of abstaining coffee for 3 months.

Historia
Four-and-a-half billion years ago, Planet Earth was formed from a vast spinning nebula of cosmic dust, the detritus left over from the birth of the sun. Within the next 100 years, human life on swathes of the Earth's surface will end in a haze of heat, drought, and, again, dust. Dust is a legacy of 20th-century progress and a profound threat to life in the 21st century. And yet dust is something we hardly ever consider--it is so small and so mundane as to be beyond the threshold of thought. Jay Owen's Dust sparks curiosity and corrects that oversight.

Excellent content with insightful link between dust and water. Less content than desired on air quality technical aspects.

Historia
The industrial age made possible by fossil fuels will surely decline as these fuels run out. In The Ecotechnic Future John Michael Greer alerts the listener to possible changes future generations may face as these dwindling fuel supplies lead first to a deindustrial age, then to a society which salvages the remnants of our current plenty, and eventually to a time in which people may learn to live in balance with the environment: an ecotechnic society.

EROI concept and solar missed
Revisado: 12-27-21
The book presents good insights in various topical area. However, a consistent theme is that fossil fuel is diminishing and nothing can be done about it. Humanities and cultures has to adapt in stages.
In defining the concept of "net energy", the author misunderstand the concept of energy return on energy investment. Yes, fossil fuel and tar sand are low in "net energy" or low EROI and this applies to bioethanol. However, in energy research circles the EROI is not fixed but subject to two factors: source deterioration (or less probable improvement) and technology improvement.
The author is ignoring solar energy and labeling it as low in "net energy" permanently. This is not the case, Currently, solar energy has improved to a great extent becoming in some geographies the cheapest energy source ever (2 us cents per kWh). We expect lowering of this cost further in future. Concentrated fossil fuels are dense, yes, but synthetic fuels can be made using cheap electricity from solar and wind. Transportation can be electric (trains and cars) and the aviation can use synthetic fuels or continue to use fossil fuels (with balancing carbon capture).
Is there possibility of technological collapse? may be. However, it is also possible that humanity under improved renewable electricity could usher a new era of improvment.
Energy is dynamic and improvements and deteriorations are acting at the same time. Energy efficiency in using the energy could reduce the energy needs. It has been demenstrated that a building can be kept worm not by an external energy but thermal energy of the sources inside (human bodies, electrical and electronic equipment).
Negative future is possible but positive future is possible too. We can steer toward a good one.

Historia
Yes, the world faces substantial environmental challenges - climate change, pollution, and extinction. But the surprisingly good news is that we have solutions to these problems. In the past 50 years, a remarkable number of environmental problems have been solved while substantial progress is ongoing on others. The Optimistic Environmentalist chronicles these remarkable success stories. Endangered species - from bald eagles to gray whales - pulled back from the precipice of extinction.

Nice book but lacks depth in some of the topics covered. Numbers presented are not always properly scaled.
