The need for new ocean conservation strategies in a high-carbon dioxide world


The historically unprecedented threats to the marine environment posed by increasing atmospheric carbon dioxide will probably require the use of unconventional, non-passive methods to conserve marine ecosystems. Soliciting such approaches and evaluating their cost, safety and effectiveness must be part of a robust ocean conservation and management plan going forward.
