Phytoplankton are microscopic single–celled plants. They synthesize organic compounds using the energy of the sun. These very–very tiny grasses sustain the entire food chain in the southern oceans. Scientists tell us that any further depletion of ozone layer will have a bad effect on the activity of these single celled plants. In turn, the whole food chain will be disrupted. That will endanger the lives of all sea creatures as well as birds in this region. Therefore, if we take care of phytoplankton or the ozone layer, everything else will take care of itself.
