The interaction of climate and non-climate drivers endangers the supply of non-food consumable products developed from marine organisms . This broad class includes nutraceuticals , food preservatives or additives , pharmaceuticals  or cosmetic products  . But biodiversity changes, warming, acidification and non-climate drivers  may decrease the availability of these organisms or the potency of the compounds they produce . Observed and projected declines and movement of fish stocks due to fishing pressure and climate change impacts  have generated concerns that the supply and safety of fish and krill oil for human dietary supplements may decline . This risk can be lowered by technological adaptations , such as increasing the use of alternative sources like marine phytoplankton, macroalgae, marine microbes  and underutilised resources such as fish, seal, crab and shrimp byproducts , and by improving extraction and processing efficiency . Climate effects on non-food consumable products could be widespread yet poorly detected, complicating assessment of impacts, risks and vulnerability reduction.
