Keeping Oregon's marine reserves protected

Oregon should keep its new marine reserves free of wave energy facilities, argues Mark Hixon (1999) in an op-ed. Even though the facilities produce sustainable energy, they generate electromagnetic fields that "have the potential to affect migrating whales and other sea life, change the local ocean environment, and impact the seafloor and associated life." Hixon instead supports siting wave energy facilities elsewhere.

Better management of wild fish needed

Sala

Declining wild fish stocks in northern oceans has driven a southward expansion of fishing at roughly one degree latitude per year for the past half-century, finds a new study co-authored by Enric Sala (2005). The authors advised that decision-makers need to encourage more sustainable fishing development instead of allowing expansion in the face of depletion.

Assessing global agriculture

Current agricultural practices have "destroyed huge regions of natural habitat" and produced "30% of greenhouse-gas emissions" and yet fail to feed a billion people, note Ruth DeFries (2001) and 24 other scientists in an op-ed in Nature. To address these shortcomings, the authors advocate for stakeholders to come together to create a freely available data network to monitor the success of agricultural systems based on social, economic, and environmental outcomes.

New standards for sustainable shellfish farming

Standards for making shellfish farming sustainable have been released by the Bivalve Aquaculture Dialogue of the World Wildlife Fund. Shellfish producers, scientists, and conservationists are among the stakeholders who took part. Sandy Shumway (2001), a member of the global steering committee for the dialogue, says the standards will help shell fishers "to maintain their culture facilities in a sustainable manner, while allowing shellfish aquaculture to continue to grow and help meet the global demand for more seafood." Click here to read and comment on the standards.
