mostly, made up of bacteria and phytoplankton s mucus secretions. so what am i looking at right here? this little guy is just one of the phytoplankton species that he says is just one ingredient in that deadly nastiness under water. the sea of marmara is just like a coronavirus patient who s been intubated, the professor explains. because the oxygen at the greater depths is almost completely depleted. it s close to zero. the professor slides his hand underneath a blanket of thick mucilage on the sea floor. not only does this suffocate everything, but it, also, steals the oxygen at these depths as it decomposes, creating dead zones. but phytoplankton is one of the lynchpins of life on the planet. it s not the villain here. the imbalance that caused all of this? us. humans. our pollution.

from cruise ships. interesting. but really, the ultimate source here is that it s a design flaw, that the plastic pollution that we find in the oceans was designed without a recovery in mind. the good news, there are solutions. there are design sdutions, with more public awareness and policy change. you mean for the actual material itself, so that it decomposes? no. designing objects that are recyclable and recoverable. for example, i ll show you, we found these. go ahead. what are they? these are umbrella handles from disposable umbrellas in japan. these are the disposable lighters. it s a disposable culture that s creating these garbage patches in the world s oceans. thank you. up next, i ll bring back my experts for one final thought. s. love this guy. so sorry.
maritime industry from fishing boats and cruise ships. really, the ultimate source here is it is a design flaw. the plastic pollution we find in the oceans was found without a recovery in mind. there are solutions. there are design solutions, solutions with more public awareness and policy change. you mean for the actual material itself? so that it decomposes? exactly. designing objects that are completely recycleable and recoverable. we found these. what are they? these are handles from disposable umbrellas in japan. we find disposable lighters. thank you, guys. we appreciate you joining us here on cnn. i am going to bring back my experts for one final thought.
