Researchers say plan could jeopardize oceans by introducing toxins into the food chain
An experimental plan to fight global warming could cause blooms of poisonous algae in seafood-rich stretches of the open ocean, say researchers at the University of South Carolina.
For more than 20 years, scientists have discussed whether adding iron to the sea could effectively keep carbon dioxide out of the atmosphere by causing the increased growth of phytoplankton, a tiny ocean plant that absorbs the greenhouse gas from air.
