Geoengineering – is it possible to really engineer our ecosystem?

Today is the start date for a program in which iron based fertilizer will be seeded into a swath of the southern ocean. That will cause a massive algae bloom, and (in principle) soak up carbon dioxide. The notion is that, I suppose, it will stay in the ocean end up as sediment.

The Science short news article is not heavy on the details, but I at least wonder about the possibility of harvesting that algae. But it’s a secondary interest. The bigger issue is: we can certainly inadvertently cause unintended effects on the climate; can we really hope to create intended consequences as well?

I saw a TED talk on that a while back, and thought it was great.

Hope you enjoy.


New documentary, F.L.O.W, and why bottled water is absurd

F.L.O.W. is a new documentary on water. On Democracy Now Sept. 12 2008, they discussed it and, in particular, the topic of bottled water. When I was in Ukraine, I was told both by locals and by the tour guide that it was not smart to drink the local tap water (unless it was boiled). Ukraine is a whole different situation than in the U.S. We have clean tap water here. The water out of your tap is more tightly regulated and is almost certainly more safe than bottled water. And it is orders of magnitude cheaper.


The oft-quited statistic is that the U.S. alone spent $15 billion on bottled water in 2007. Well, check this out:

“The United Nations Millennium Development Goal for environmental sustainability calls for halving the proportion of people lacking sustainable access to safe drinking water by 2015. Meeting this goal would require doubling the $15 billion a year that the world currently spends on water supply and sanitation”

With what the U.S. alone spends on bottled water that we don’t need we could alleviate the very real need for half of the world’s population. That, ladies and gentlemen, is shameful.
