Placed by Ayse Aydogan Gezer 2020/Oct/22
Description:
We observed that some pollution was not water, even if we tried to pollute the water polluting substances and especially clean them. We imagined a polluted sea. we cleared the sea. but we couldn't clean the oil somehow. That's why we talked about the need to be careful about not mixing oil wastes with water.
