How do marine plants help stop global warming?? Someone told me but never explained

%26quot;As stated, phytoplankton fix carbon in sunlit surface waters via photosynthesis. Through (primarily) zooplankton grazing, this carbon enters the planktonic foodweb, where it is either respired to provide metabolic energy, or accumulates as biomass or detritus. As living or dead organic material is typically more dense than seawater it tends to sink, and in open ocean ecosystems away from the coasts this leads to the transport of carbon from surface waters to the deep. This process is known as the biological pump, and is one of the reasons that the oceans constitute the largest (active) pool of carbon on Earth%26quot;

they do nothing to help stop global warming. global warming doesn%26#039;t exist. It%26#039;s a natural earth cycle. In 500 years, liberals will be worried about global cooling

I have herd that many of them are switching to solar and wave energy to help eliminate the use of fossil fuels.

because it lets out oxigen
