Conserving life's diversity: can the extinction crisis be stopped?
Article Abstract:
Conservation biology has only recently become an urgent policy issue, though the destruction of biological diversity by overpopulation, overconsumption and misguided resource management has been acknowledged for years. The loss of species and ecosystems affects our air and water and fish and crop production. Loss of genetic diversity allows diseases to wipe out crops. Lately, advances in scientific understanding, economic incentives of pharmaceutical and agricultural biotechnology and grassroots efforts in developing countries have contributed to a global biodiversity conservation movement.

Uptake of haloacetyl and carbonyl halides by water surfaces
Article Abstract:
The use of a bubble column apparatus to analyze heterogeneous interaction between haloacetyl and carbonyl halides and water revealed slow tropospheric removal of the halides. The results were confirmed by the measurements obtained from the computation of Henry's law of solubility and hydrolysis rate constant. They showed a 30-day limit to the lifetime of haloacetyl and carbonyl halides in the atmosphere. This suggests that removal of these gases from the atmosphere have no effect on ozone layer depletion.
