A sustainable way to conserve birds

http://www.nytimes.com/2014/04/15/science/paying-farmers-to-welcome-birds.html?ref=science&_r=0

In California, a area that was once wetlands is now 95% farm land and the result was a dramatic decrease in migratory birds. Conservationists have found an innovative way to preserve these birds. By using a smartphone app to record bird locations, scientist have determined the key areas to be preserved for the birds. Now instead of buying the habitat from the farmers, conservation organizations just pay to irrigate certain areas for a few weeks at a time.

Environmental Meat Vs. Ethical Meat Vs. No Meat

Yesterday I came across an article in NPR’s The Salt blog which I found to be somewhat disheartening. In Why Farmers Can Prevent Global Warming Just As Well As Vegetarians, factory farming-like practices are touted as the best solution for mitigating greenhouse gas emissions from the livestock industry.

In no way am I questioning the logic behind the article’s source. As the demand for animal products rises globally, so will the already vast emissions from the livestock industry due to feeding, raising, transporting, and the creation of new grazing lands. Thus, per the findings of the study, animals should be raised in an industrial facility on grain, and the creation of new grazing land for livestock should be avoided. (It should be noted that “grain” may not mean what you think it means.) It makes sense that deforestation is not good, and that “…transitions toward more productive livestock production systems…” should be more efficient and economical, but at what cost ethically? Neither the article nor the abstract of its (pay walled) primary source explicitly mention the practices that factory farms are notorious for; however, it’s fairly easy to make that connection when their recommendations rely heavily on limiting land use and altering livestock diets. Is this really a solution that we should be suggesting to developing nations?

Through all of this, I am still having trouble understanding how the factory farming of meat can somehow be just as eco-friendly as non-consumption, and it saddens me to realize that the escalation of these farming practices are the likely outcome when compared to simple restraint.

Interesting Segment from NPR’s TED Radio Hour

If you haven’t heard of it before, I think NPR does a really nice job putting together their podcast, TED Radio Hour.  As the title suggests, it’s a selection of related TED talks, but also mixes-in interviews with each of the featured speakers. The show translates well to an audio podcast but the video for each talk is easily accessible from the NPR website.

The episode from last week was titled, Everything is Connectedwhere the theme was based on “…how everything in nature is connected, and how we can restore its delicate balance.”  If you only had time to listen one segment, I would suggest, What Listening To Nature Teaches Us About Changing Habitats.   The segment features Bernie Krause, who has been recording the sounds of nature for over 45 years.  From the NPR link:

Bernie Krause is a bioacoustician whose recordings have uncovered nature’s rich sonic tapestry — along with some unexpected results. Krause captures the fading voices of nature, studying sonic interplay between species as they attract mates, hunt prey and sound out their roles in the ecosystem. His documentation of vanishing aural habitats is a chilling reminder of shrinking biodiversity.

Snow Geese

As promised, here are a few pics of snow geese, all from within 10 miles of campus. The first shows several flocks passing high over my barn when I got home yesterday. Click for larger image.
