Many experimental projects that include dumping massive amounts of magnesium oxide into the ocean to bind carbon dioxide. Other companies are experimenting with “sinking rocks, nutrients, crop waste or seaweed in the ocean” to try to lock away carbon dioxide. It seems backward to do huge experiments on the ocean while we are still pouring greenhouse gases into the atmosphere. If Americans told their legislators they want a quick transition to renewables and continued small-scale experiments on ocean sequestration of CO2, this would become a safer and healthier world. ~ Nancy Hasenfus, Brunswick
