While macroplastic pollution has been researched for >50 years, it has only recently become clear that microplastics are widely prevalent and hazardous. The consequences of microplastics exposure are poorly studied, meaning many wild species that consume plastic may suffer effects of which we are unaware. Nearly a decade of research into ingestion of macroplastics suggests Flesh-footed Shearwaters (Ardenna carneipes) experience reduced body condition, altered blood chemistry, and increased chemical concentrations in their tissues. Recent pilot data for microplastics indicates environmental factors change the inflammatory properties of particles. In our seminar, we review the documented sublethal effects of plastic ingestion in this species, and discuss preliminary results that identify inflammatory responses that are an emerging conservation concern.
