Book note: Earth in Human Hands

Planetary scientist David Grinspoon's book Earth in Human Hands: Shaping Our Planet's Future, which I mentioned recently, has been published, and is well worth readers' time. I say this based on partial but compelling information, having not yet finished reading my review copy; but I have certainly read enough to say this is an important, timely and thought-provoking work.

It is also one that will spark some controversy, perhaps along the lines of the ideological shake-up I've anticipated, in which stock answers from left and right become less predictable as environmental problems grow along with human capacities to possibly do something about them. In his final chapter (I jumped ahead) "Embracing the Human Planet," Grinspoon is critical of environmental doomsaying such as accompanied incorrect reports a couple years ago that NASA had predicted civilization's collapse.

"If this human bashing and doom prophesizing is tactical, I think it's backfiring. It's more likely to become a self-fulfilling prophecy than to rouse people to action," writes Grinspoon. He continues:
"Currently I feel that spewing misanthropy and random anti-human sentiment is just as dangerous as emitting CO2 into the air. It is the opposite of activism. I know that people spreading these messages mean well. They want to shock others into realizing the effect we're having on the planet, but there is a real danger of unintended consequences, of encouraging people to give up. Spreading messages of doom is a form of inactivism."
Me: While passages such as that may discomfit environmentalists, I should add that there is much to discomfit others, including anyone who's gung-ho for some hands-on geoengineering. Also, because Grinspoon's a planetary scientist, this book has a strong element of celestial perspective, as well as anecdotes about Carl Sagan and other space-focused luminaries. As I suggested in my earlier note, about this book and David Biello's The Unnatural World: The Race to Remake Civilization in Earth's Newest Age, questions about what humans should do on a large scale and for the long term are getting more important every day.
