Do you know that plastic has been recently found in the deepest part of the world ocean ? Mariana Trench is almost 11 000 metres deep, but the depth didn't save this nature wonder from pollution caused by mankind in general and each of us in particular. My piece is to remember us, how beautiful and at the same fragile nature is. If we do not act, out children won't be able to see it, even we won't. Such simple accessible pleasures as bathing in the clean water or making photos of sea views for Instagram won't be possible in the nearest future. In fact, it is more near than we even imagine. And the change is highly likely irreversible.
