人間の活動によって大量のプラスチックが生み出されている。それは海へと流れ、煽られ、砕かれ、マイクロプラスチックとなって半永久的に海中に蓄積される。マイクロプラスチックとは、生物物理学的環境中に存在する微小なプラスチック粒子であり、特に海洋環境において現在、極めて大きな問題になっている 。
 この作品は、マイクロプラスチックを用いた音響彫刻。それは、砂時計の形をしていて、その中には砂ではなく、マイクロプラスチックが入っている。 マイクロプラスチックは、時を刻むように上から下へと流れ落ちて音を刻む。その音は、脅威の存在を主張するようでもあり、自らを自然の代替として私たちを誘惑するかのように綺麗に澄んでもいる。
マイクロプラスチックは今この瞬間にも増え続けている。2050年には海にあるプラスチックの量が魚の量を超えると言われている。人間がいる限りそれは永遠に繰り返され、後戻りは決してしない。
  This work is a sound sculpture of microplastics. The shape is the sand glass in which microplastics are, not sand. Microplastics flow down like they tick away the seconds. The sounds that microplastics beats are recorded with the concrete microphone set on the bottom of the sandglass. They are designed as natural sounds like those of sands and also gloomy sounds to threaten us with digital sound processing. That emphasises microplastics behave themselves as alternatives to nature and also keep hidden threats of themselves. A sandglass keeps ticking the seconds eternally as long as people can turn it over. This sandglass implies microplastics are increasing and accumulated eternally because of our doing. Time is irreversible.

 We went to the coast to gather up microplastics that are mixed among sand. Only microplastics can be found floating on the water including sand in a bucket due to buoyancy.


 A large amount of plastics are generated from human activity. They are carried to the sea, waved, and piled up permanently as microplastics. Microplastics are tiny plastic pieces that exist in human life especially into the ocean. Their existence causes the environmental issue of plastic pollution. Plastic pollution disrupts ecosystems in the sea. Fish, shellfish and seabird mis-swallow microplastics in the seawater, and are led to death because of indigestion and gastric ulcer. The amount of microplastics in the earth can't stop increasing. It is said that the amount of microplastics exceeds that of fish in the earth in 2050. Plastics are able to make our life comfortable. However, they are also weapons to kill a variety of lives in the sea.
