The Great Pacific Garbage Patch
Uncover the reality of the world's largest ocean plastic accumulation and learn how systems-level changes can protect marine ecosystems.
Course introduction
The Great Pacific Garbage Patch is often imagined as a floating island of trash you could walk on, but the reality is far more complex and dangerous. It is a massive "soup" of suspended microplastics and discarded fishing gear, trapped by powerful ocean currents. In this course, you will dive into the science of how this patch formed and why plastic is uniquely persistent in our oceans.
You will explore the hidden pathways where plastic enters the food chain, threatening both marine life and human health. By looking beyond simple cleanup myths, you will discover the roles of circular design, policy, and individual habits in stopping plastic at the source. Get ready to shift your perspective from visible litter to the invisible systems that drive global pollution.

When we talk about the Great Pacific Garbage Patch (GPGP), many people imagine a solid mass of land you could walk on, perhaps even plant a flag in. However, the reality is far more subtle and, in many ways, more dangerous.
This module takes you deep into the North Pacific Subtropical Gyre to understand the physics of the 'vortex' and the chemistry of why plastic never truly goes away. You will learn to distinguish between popular myths and scientific facts, setting the stage for exploring the broader environmental impacts on our planet.
Understanding the Great Pacific Garbage Patch requires looking beyond the floating debris to see the biological ripple effects that extend throughout the ocean. In this module, you will investigate how tiny microplastics become toxic delivery vehicles for marine life and why large-scale 'ghost gear' remains a persistent physical threat to biodiversity. By exploring the connections between ocean health and human food security, you will see why the health of the North Pacific is directly linked to your own plate and community health.
Stopping the growth of the Great Pacific Garbage Patch requires more than just high-tech nets in the middle of the ocean. It requires a shift in how we design, use, and dispose of materials on land. In this module, you will trace the pathways plastic takes from your laundry room and local storm drains to the high seas.
You will also explore the circular economy and the global policies designed to hold manufacturers accountable, moving the focus from downstream cleanup to upstream prevention. By the end of these lessons, you will see how community action and industrial innovation work together to close the tap on ocean plastic.
The UN SDGs are 17 global goals for a fairer, sustainable world by 2030.

This course directly addresses the urgent need to protect marine ecosystems from plastic pollution, as highlighted by SDG 14. By understanding the Great Pacific Garbage Patch and the persistence of microplastics, you learn about significant threats to ocean health. Your exploration of circular design, policy, and personal actions contributes to preserving marine life. This knowledge is vital for preventing pollution and working towards healthier, more resilient oceans for all.
Reviews
I thought I knew a lot about the Great Pacific Garbage Patch, but this course truly opened my eyes to the scale of the problem and its complex impacts on marine life. The content went beyond just the visual horror, diving deep into the systems contributing to plastic accumulation and offering practical insights into how large-scale changes can make a real difference. I feel much more informed and empowered to advocate for sustainable consumption and protection of our oceans.
This course provided an incredibly clear and impactful dive into the Great Pacific Garbage Patch. I now have a much deeper understanding of the plastic crisis and feel inspired to contribute to protecting our precious marine environments through responsible consumption.
