Researchers are trying to use iron to stimulate phytoplankton growth. phytoplankton removes excess carbon from the atomosphere because too much carbon makes the earth warmer. if researchers are correct, adding iron to stimulate phytoplankton

Global warming is an issue in today’s society. Since phytoplankton helps remove excess carbon from the atmosphere, it can decrease the temperature of the earth and may help slow global warming. When carbon dioxide is decreased in the air, it reduces the temperatures. Carbon dioxide traps heat on the earth’s surface, so eliminating it can make the earth cooler.
