As we watch in horror the devastation in Southern California, our thoughts go out to the families that are suffering, along with our thanks to the heroic firefighters working tirelessly to bring this tragedy to an end. The removal efficiency ranged from 11% to 26%. Seed-dispersing birds (quantified at one site only) showed an overwhelming preference for islands; 160 visits were recorded to islands compared with one visit to open pasture. However, the former are more expensive and the latter are time-consuming and have unstable efficiency.

The Application of Solar Cells in the Electrokinetic Remediation of Metal Contaminated Sediments. The removal efficiencies (CA) ranged from 78 to 82% for Ni, Cu, Zn and Cr. Perhaps more importantly, Sharma says hes witnessed people in resources-depleted communities change over the years, from assuming land is bad and will stay that way, to now imagining forest. Hes dedicated to making more of that verdant possibility come true, and to bringing back, he says, everything [we can] that has been lost to agriculture, monoculture, cities, lawns.
