In this episode, I explore the microscopic world of plankton – the drifting organisms that underpin marine food webs and help produce the oxygen we breathe.
 We look at phytoplankton and zooplankton, their role in food chains, climate regulation, and why changing oceans make these “invisible” communities so important to understand.

Key topics in this episode

·       What plankton are and why “drifters” matter.

·       Phytoplankton as primary producers and oxygen sources.

·       Zooplankton and food chains from microscopic to fish, birds and marine mammals.bbc+1

·       Plankton, carbon cycling and climate.whoi+2

Threats: climate change, harmful algal blooms and changing plankton communities. 

• If this episode helped you see plankton and plastic differently, share it with someone who cares about ocean health or teaches biology or environmental science.
• I’d love to hear your thoughts on plankton as bioindicators, microplastics and One Health – send your questions or suggestions for future episodes focusing on animal nutrition, microbiomes and environmental toxicology.

The information in this episode is based on ongoing studies, emerging research and my own interpretations as an animal science student. I do my best to stay balanced and reflect the current evidence, but the science around microplastics and nanoplastics is still developing.
