From Plastics to Particles to Action



Plastics are lightweight, low-cost, and durable materials that have become an essential part of modern life. From 1950 to 2022, global annual plastic production increased from 2 million tonnes to 474 million tonnes [1]. They are used in everything from electronics and clothing to packaging and construction, and can be found in everyday products such as bottles, toys, food containers, blankets, trash bags, rope, furniture, paint and more. It is estimated that 30% of all plastics ever produced are still in use today, 60% have been disposed of in landfills or entered the environment, and 10% have been recycled or incinerated [2]. This means that roughly 4900 million tonnes of plastic, 60% of all plastic ever produced, is in landfills or in the natural environment, where it will not biodegrade but instead fragments into particles ranging from millimeters to micrometers in size.


Microplastics (MPs) are defined as plastic particles less than 5 mm in size that vary widely in shape, color, density, and polymer type [3]. They are classified into two categories: primary MPs, which are manufactured for commercial and industrial uses (e.g. nurdles, microbeads, glitter, and synthetic textiles), and secondary MPs, which form from the fragmentation of larger plastics (e.g. water bottles and plastic bags). They have been found in almost every area of the planet from the Arctic [4], to deep seas [5], at high altitudes [6], and in soil and groundwater [7]. Due to their resistance to degradation, MPs persist in the environment for extended periods, posing long-term environmental and human health risks. They have been detected in air, soil, water, plants, animals, and humans [8]. MPs can infiltrate the human body through ingestion of contaminated food and water, inhalation of polluted air, and dermal exposure to products that contain microplastic materials [9]. Early human clinical and epidemiological research studies report possible links between MPs and disease [10,11,12,13].


The Great Lakes are a source of drinking water for 40 million people and hold 21% of the world’s surface freshwater. Yet plastic pollution is a growing threat with millions of pounds entering these waters annually, including an estimated 5.6 million pounds in Lake Erie alone [14]. Most of the shoreline litter is plastic, and in 2021, volunteers removed 25,000 pounds of trash from the Great Lakes beaches, 85% of which was plastic [15]. Over time, this debris fragments into microplastics, further contributing to pollution already present in the lakes.


The Watershed Volunteer Program (WVP) is working to address this issue through The NOAA Marine Debris Monitoring and Assessment Project, which collects data to better understand and prevent the impacts of marine debris. Volunteer-collected data (WVP Euclid Beach) are publicly available and help guide regional cleanup and prevention efforts. You can make a difference by joining one of our upcoming (M) Marine Debris Monitoring events:


  • Sun, Aug 10, 9 - 11 a.m. @ Euclid Beach in Euclid Creek Watershed
  • Sun, Sept 14, 9 - 11 a.m. @ Euclid Beach in Euclid Creek Watershed

(S) Friends of the Doan Brook Gorge Habitat Stewardship

Sat, Aug 9, 10 a.m. - 12 p.m. @ Doan Brook Gorge

A few years ago, some friends got together to start removing invasive species and planting native species in the Doan Brook Gorge in the hopes of making it a more resilient and accessible spot for community members to spend time in nature. Filled with meandering trails and multiple waterfalls, the Doan Brook Gorge is a beautiful and often under-utilized natural area of the Doan Brook watershed.

This year, we are hosting 6 “Habitat Stewardship Days” which will involve invasive species removal, native tree plantings, and so much more! Join us in helping to make the Doan Brook Gorge a more biodiverse and welcoming outdoor space for all!

(S) Invasive Plant Removal Drop In

Thurs, Aug 14, 1 p.m. - 3:30 p.m. (Must register for location)

Are you looking for a way to get involved at Cuyahoga Valley National Park? Join us for our invasive plant removal drop-in on Thursday, July 10, to improve habitat for native plants and wildlife! Invasive species overcrowd native species, making it difficult for them to thrive, which in turn affects the wildlife in the ecosystem. Your efforts will help improve soil quality, restore native plants, and create better habitat for native wildlife. Drop-ins are a great opportunity for both first-time volunteers and veteran volunteers to get involved in their national park.

(S) Take to the Lake

Sat, Aug 23, 10 a.m. - 4 p.m. @ Lower Shaker Lake, Brook Rd. Shaker Heights

Doan Brook Watershed Partnership has been hosting our annual event Take to the Lake which was started in 2013 as a memorial to Lester Stumpe, an avid paddler and early DBWP board member. We typically host the event on the last Saturday in August and this years event details can be found below. Canoeing on the Shaker Lakes was a popular pastime in the first half of the 20th century, but public boating on the lakes is now less common. Take to the Lake gives participants a chance to resurrect this recreational opportunity for a day, and gain a new perspective on the lakes and their place in our watershed community. We hope you will join us for an afternoon of paddling, guided hikes, yoga, along the banks of historic Lower Shaker Lake.

(S) Lower Lake Hike with Dr. Roy Larick & Shaker Historical Society

Sat, Aug 23, 11:30 a.m. - 1 p.m. @ Lower Shaker Lake, Brook Rd. Shaker Heights

Join Dr. Roy Larick (Bluestone Conservation) and the Shaker Historical Society for a 90-minute interpretive hike around Lower Shaker Lake. Learn how Doan Brook emerged with the retreat of the last glacier 14,000 years ago. Comprehend the evolution of the native forest as snowbelt conditions came to the East Side Heights some 4,000 years ago. Take in the transformations brought about by Shaker milling nearly 200 years ago and by suburban development already 100 years in passing. Gain insight on the management choices we face as temperature and rainfall increase, and as alien plants and animals come to displace the natives. How can Doan Brook help us live more equitably with each other and with local nature?

The Short-Lived Sand Octopus From Across The Pond

Last month, the British art group Sand In Your Eye decided to make a masterpiece along Watergate Bay in Cornwall, England. Using only rakes and ropes, they spent hours shaping the image of a giant octopus into the sand. Measuring 100 meters across, it was created to kick off the Enchanted Earth Initiative -- an event celebrating the hidden and rarely seen wonders of the natural world that runs until early September. Unfortunately, this magnificent shoreline cephalopod only lasted for a few hours before getting washed away under the incoming tide.
