Primary production is limited in much of the open ocean by low levels of iron, which is a necessary phytoplankton nutrient. It has been suggested by some that pumps could be placed in these areas that would move iron-rich sediments from the deep into the well-lit euphotic zone, thus stimulating phytoplankton blooms. What problem (human impact) do you think scientists would be trying to address with this biotechnological approach? (3 points)
Reduction of the human impact on marine species diversity
Reduction of bycatch
Reduction of the greenhouse gas carbon dioxide in the atmosphere
Reduction in iron pollution in oceanic sediments
