In this investigation, students describe the life cycle of man-made products that include or originate from plastic to evaluate how they may impact the environment. Students use a basic life cycle assessment – similar to assessments used by process engineers – that allows them to identify and order the different steps in the life cycle of a product. Using their analyses to compare the impacts of different products, students develop ideas to reduce the environmental impact of the production process or lifecycle of the product.

All of the plastic that we as humans have made is still somewhere on the planet, so what solutions exist to help not only remove up from places where it is causing damage but also repurpose the ubiquitous material? Philippe Cousteau hears from experts, including Donna Shiel from Sustainability Victoria, Heidi Taylor from Tangaroa Blue, Anthony Hill from Plastic Pollution Solutions, and staff from the Melbourne Zoo about what options are available to replace plastic use and what you can do to help solve the global issues of PlasticSeas.

In order to develop solutions to the challenge of plastic pollution, we must track plastic to its source. Philippe Cousteau travels to the Port Phillip EcoCentre to meet with Baykeeper Neil Blake, who explains how plastics find their way into the Bay. Philippe then hits the water with 5 Gyres Ambassador Blair Stafford to trawl for microplastics.

Philippe Cousteau meets with Dr. Kate Charlton-Robb, the founding director of The Marine Mammal Foundation, to explore how marine ecosystems--specifically a unique population of dolphin--are impacted by plastic. From marine mammals to seabirds, plastic has a variety of impacts that Philippe examines with Dr. Jenn Lavers, who studies the health of seabirds through some unusual sampling methods.
