The University of Minnesota Biocatalysis/Biodegradation Database (UM/BBD) contains "microbial biocatalytic reactions and biodegradation pathways primarily for xenobiotic, chemical compounds." A new microbial enzyme-catalyzed reactions has been posted for 2,4-Dichlorophenoxyacetic Acid. 2,4-dichlorophenoxyacetic acid (2,4-D) is used in cultivated agricultural areas, rangeland and pastures, forests, and homes or gardens, and is "a chlorinated phenoxy compound [that] functions as a systemic herbicide and is used to control many types of broadleaf weeds." The degradation pathway map includes organisms which can initiate the pathway. The pathway map provides detailed information on each hyperlinked step, including graphics, product/substrate reactions, and external links to further information.

Relates to linked video, DragonflyTV GPS: Earthquakes.

This radio broadcast discusses the findings of a conservationist who flew over of most of the continent of Africa in a small plane at low altitude, photographing the ground below every 20 seconds, to form a grid map. The flyover was intended to evaluate human impacts on African ecosystems, including wildlife, vegetation, and soil. The researcher, Dr, Michael Fay, points out that humans have penetrated very deeply into every single ecosystem in Africa that was visited, exhausting soils, vegetation, and water systems. He also discusses the need for greater natural resource management to locate the places where humans have already exceeded what the ecosystem can sustain. The broadcast is 7 minutes and 45 seconds in length.
