On micro-plastics and space junk
The Great Pacific Garbage Patch (GPGP) is the largest of the five offshore plastic accumulation zones in the world’s oceans. It covers an estimated surface area of 1.6 million square kilometers and its mass is estimated to weigh 80,000 tons. It is also estimated that 1.15 to 2.41 million tons of plastic are entering the ocean each year from rivers.
Many plastics break into smaller pieces and become microplastic pollution. Some plastic fragments are already 5 millimeters in size or less before entering the environment. What are the consequences of microplastic pollution in local and international waters?
The term space debris originally refers to the natural debris found in the solar system. However, it also describes the debris from the mass of defunct, artificially created objects in space, especially in Earth’s orbit. These include old satellites and spent rocket stages, as well as the fragments from their disintegration and collisions. In 1957, Sputnik brought to space the first pieces of space junk. In January 2019, more than 128 million bits of debris smaller than 1 cm, about 900,000 pieces of debris 1–10 cm, and around 34,000 of pieces larger than 10 cm were estimated to be in orbit around the Earth. What are the technical, economic, and legal aspects of the orbital debris?

About this Project
NATURA NATURANS is an artist-driven educational experiment that consists of lectures, workshops, field trips, and an exhibition exploring our changing understanding of nature in the Anthropocene. Curated by the artist Anne-Sophie Coiffet, who divides her time between DC and Paris, this twelve-week project examines topics as varied and interrelated as the co-mingling of natural and human objects and systems, securing legal status for ecosystems, silent places and acoustical trash, genetically modified crops and butterflies, space junk and oceanic micro-plastic, and more.
