Some people have suggested that fertilizing the oceans with iron would help combat the effects of global warming on oceans.However, it is unlikely that this method will be used extensively, because iron fertilization A) does not affect the impacts of global warming on oceans. B) causes more CO₂ to be dissolved in oceans. C) increases photosynthesis, thereby decreasing dissolved CO₂. D) would be very difficult to do on a large scale. E) would be ineffective because its effects are indirect, not direct.

Question

Quizplus · Accepted Answer

Iron fertilization would be difficult to do on a large scale because it would require vast amounts of iron, which is a limited resource, and would also have significant logistical challenges in terms of dispersal and monitoring of the effects. Additionally, there are concerns about unintended consequences and potential ecological impacts of large-scale iron fertilization. Therefore, it is unlikely to be a widely used method for combatting the effects of global warming on oceans.
