Tiny Plastics, Big Impacts: A Wake-Up Call on Microplastics at Penn
Plastic pollution has moved beyond oceans and landfills — it’s now in our food, water, and even our bodies. In a creative and eye-opening event at the University of Pennsylvania, students confronted this unsettling reality through a blend of science, shock, and cookies.
As part of Penn Climate Week, the Tiny Plastics, Big Impacts event aimed to transform how students think about plastic consumption. Organized by Joey Wu, a 2024 EarthEcho Marine Plastics Ambassador, in collaboration with Penn researchers and environmental groups, the initiative used innovative outreach to drive home a serious message

Set up along Penn’s busy Locust Walk, the event drew in 250–300 attendees with an attention-grabbing treat: credit-card shaped cookies symbolizing the estimated amount of plastic humans ingest each week — about 4.1 micrograms. The reaction was immediate and visceral. That shock opened the door to deeper conversations.
At nearby tables, Dr. Derek Ho, Dr. Jon Hawkings, and Dr. Samantha McBride — all prominent researchers at Penn — shared their insights on the environmental and health impacts of microplastics. They discussed topics such as the prevalence of microplastics in bottled water brands like Fiji, Dasani, Aquafina, and Liquid Death. Students also participated in the interactive “Plastic Panic” game, exploring practical strategies to reduce their plastic use, and many signed a pledge to lower their plastic footprint.

Beyond the numbers, the event sparked genuine enthusiasm and new interest in environmental research, with some students even considering independent research projects on plastic pollution. By combining science, art, and a bit of culinary creativity, Tiny Plastics, Big Impacts showed that environmental education doesn’t have to be traditional — it just has to connect.
“A little creativity in the environmental field goes a long way,” said Joey Wu. “With this experience, I’ve seen how powerful innovative outreach can be in building a movement for climate justice.”

Microplastics are everywhere, but our ability to monitor them is still limited. We want to change that by combining long-term environmental monitoring, community participation, and accessible scientific tools.
Building a long-term monitoring network
With community partners, we hope to establish weekly monitoring of microplastic loading in the Schuylkill River, including locations upstream and downstream of the dam. Repeated sampling can help us understand how microplastic pollution changes with rainfall, seasons, water flow, and other environmental conditions.
We also hope to expand watershed monitoring to locations including neighbouring Creeks, wetlands, stormwater pathways, soil and sediment, and areas surrounding synthetic turf at FDR Park.

Asking questions about the products we use
Our work won't stop at waterways. We also want to investigate microplastics in commercially available water, beverages, and selected food products.
And the community will help decide what questions we investigate.
Making microplastic monitoring more accessible
We are also working to advance new approaches for detecting microplastics outside specialized laboratories. By combining research, validation, and community participation, we hope to make microplastic monitoring more accessible to educators, community organizations, and researchers.
We don't want to simply tell communities that microplastics are everywhere.
We want to give communities the tools to investigate for themselves.

This work is only possible when people come together.
