What Are Microfibers and What Can We Do about Them?

O God of mercy, before Whose door the quintessence of mercy hath bowed down, and round the sanctuary of Whose Cause loving-kindness, in its inmost spirit, hath circled, we beseech Thee, entreating Thine ancient grace, and seeking Thy present favor, that Thou mayest have mercy upon all who are the manifestations of the world of being, and deny them not the outpourings of Thy grace in Thy days.

Washing synthetic clothing releases tiny particles called microfibers. A study found that “laundering an average washing load of 6kg (13lb) could release an estimated 137,951 fibres from polyester-cotton blend fabric, 496,030 fibres from polyester and 728,789 from acrylic.” (1)

These micro-fibers go into the water supply, the rivers, reservoirs, lakes and the ocean. They can pose a serious threat to aquatic life as well as for human health because these microscopic plastic particles are eaten by animals including fish. When fish eat micro-plastics instead of food, they starve; their growth can be stunted, and they can even die. Moreover, fish absorb toxic chemicals from plastics with still unknown consequences for them and their predators including sea-birds. For human health, this means that eating fish increasingly adds to our overall exposure to toxic chemicals, not only from these micro-plastics but also from the mercury (which comes from coal fired power plants) that also accumulates in fish. It also means that micro-plastics are a further threat to future food supply as fish populations have already alarmingly shrunk because of over-fishing.

So, what can we do? First, do not throw away your synthetic clothing, just try to wash them less often and in a more gentle washing cycle. Second, try to buy clothing from natural fibers.

Of course, individual actions are only part of the solution. The fashion industry should quickly phase out synthetic materials. This problem also calls for advances in large scale water treatment processes.

For more information about an even larger source of micro-plastics that comes from the breakdown of all plastics such as containers and bags, see the February 2021 Sustainable Living Tip on the Harm of Micro-plastics.

Christine Muller, Teacher of Music and the Environment

Board Secretary, International Environment Forum

I was interested in environmental issues already at a young age and became a Bahá’í when I was 17, which was the beginning of a life-long study of the Bahá’í Faith. As the environmental crisis was worsening, I began to systematically study climate change at a time when not much information was easily available. I also searched the Bahá’í teachings for a spiritual solution to the climate crisis. At that time, climate change was not known to most people and there were no educational materials available. That’s why I wrote Scientific and Spiritual Dimensions of Climate Change – an Interfaith Study Course, which the International Environment Forum posted in 2009. I joined the Wilmette Institute as support faculty for its Sustainable Development course in 2011 and created its Climate Change course the following year. I also teach a course on climate change for the Environmental Sciences Department of the Baha’i Institute of Higher Education (BIHE) in Iran. I have served on the board of RI Interfaith Power&Light for more than a decade. In recent years, much of my time is spent serving the Bahá’í-inspired International Environment Forum ( as its secretary.  My formal academic background is in music, and I enjoy part-time piano teaching, playing and - when there is time - composing music. A recent composition is Humans on Earth – a Ballad of Our Time for two singers, string orchestra, piano, and percussion. Its lyrics include quotations from scientific sources and the Bahá’í Writings.
