Report Blames Factory Farms for Bird Flu
By Stephen Leahy

Feb 20 (IPS) – Factory farms are responsible for both the bird flu and emissions of greenhouse gases that now top those of cars and sport utility vehicles (SUVs), according to a report released Monday.

Sixty percent of global livestock production, including chicken and pig “confined animal feedlot operations” (CAFOs), now occur in the developing world. Unregulated zoning and subsidies that encourage these CAFOs or factory farms are moving closer to major urban areas in China, Bangladesh, India, and many countries in Africa, said the report, “Vital Signs 2007-2008” by the Worldwatch Institute.

Feb 19 (IPS) – Fifteen new species of birds have been discovered in North America following the first ever genetic analysis of nearly all 690 known species. A similar DNA profiling or “bar-coding” of Guyana’s 87 bat species revealed an additional six genetically distinct bats.

These new species are nearly indistinguishable to human eyes and ears from known species but the analysis shows their DNA evolved along different paths millions of years previously, according research published Sunday in British journal Molecular Ecology Notes.
