Chemical dispersants and crude oil – efficacy and toxicity

by

One of the striking controversies about the massive BP Deepwater Horizon oil well blowout has been alarm raised about chemical dispersants used to hold spilled crude oil deep in the Gulf of Mexico. Prospects for oil’s direct harm to the environment, the economy, and coastal society were immediately obvious. But why were people so concerned that dispersing the oil was bad—worse than allowing it to come onshore? Is this just a case of “out of sight, out of mind” to benefit the oil company, or are there larger benefits that reduce the harms to other interests?

The 50-year farm bill

by

We need new strategies for agriculture that emphasize efficient nutrient use in order to lower production costs and minimize negative environmental effects. The trouble is, the best soils on the best landscapes are already being farmed. Much of the future expansion of agriculture will be onto marginal lands where the risk of irreversible degradation under annual grain production is high. As these areas become degraded, expensive chemical, energy, and equipment inputs will become less effective and much less affordable.

Our tails get in the way: The problems and principles of energy descent

by

Let us imagine human beings climbing up a rather steep and precarious tree, boosted up by fossil energies into a place we simply could never get to without them. The problems we are facing right now all originate in our fundamental inability to voluntarily set limits – that is, at no point did most of us even recognize the basic necessity of stopping at a point at which we could get down on our own, without our petrocarbon helpers.

Review: Sound Truth & Corporate Myth$ by Riki Ott

At just before 10 p.m. on Tuesday, April 20, 2010, the Transocean Ltd.-owned and BP Plc.-operated floating oil rig Deepwater Horizon was boring an exploratory well in the Macondo Prospect—about 40 miles southeast of the Louisiana coast and nearly a mile underwater—when it exploded without warning from a well blowout. …BP has tried repeatedly to stop the flow, to no avail. (As of this writing on Tuesday evening, July 13, it remains to be seen whether the well cap installed last night, a Band-Aid pending completion of the long-awaited relief wells next month, will actually work.) The spill’s magnitude has beggared description or belief.

Peak Moment 176: How we live at Lone Bobcat Woods

Peek behind the scenes at Peak Moment TV’s home base. Janaia Donaldson shows guest host Ivey Cone the solar power system, woodstove for heat (and winter waffles), and super efficient refrigerator. Choosing to reduce their footprint, she and Robyn Mallgren, Peak Moment videographer, don’t feel deprived at all. Janaia discusses what led them to leave the Bay Area, what it’s like to live on 160 acres of forestland, which they’ve preserved “in perpetuity” as a wildlife sanctuary, and shows us some of the members of the natural community they live in.
