“…To understand the impact of nanoPS42 on aggregation in these two Symbiodiniaceae cultures, the total number of algal aggregates per tank and in five aggregate size classes was recorded (Supplementary Figure S2). All tanks showed aggregation, which was expected, as self-aggregation of Symbiodiniaceae has been observed previously [13]. Figure S2).…”

“…Thus, nanoPS42 either inhibited algal growth in a non-linear manner or had a limited effect [27]. Reductions in growth rates have also been reported in the µP study of [13] in Cladocopium goreaui and in other microalgae exposed to µP (Chlamydomonas reinhardtii [28] and Skeletonema costatum [29]).…”

“…Further investigations are needed to see if this is the case under nP exposure. Interesting to note is that the biggest growth rate reduction observed was at 0.01 mg/L nanoPS42, far below the 5 mg/L used by Su et al [13]. The nutrient deficiency is also a reason discussed in (Long2017) which could explain the larger effects on growth rates at lower concentrations.…”

“…They are also linked to potential adverse effects on calcification [11] with exposure resulting in attachment of microplastic particles to tentacles or mesenterial filaments, ingestion of microplastic particles, and increased mucus production [12]. Su et al [13] exposed the coral symbiont, Cladocopium goreaui, to 1-µm polystyrene spheres, leading to diminished detoxification activity, nutrient uptake, and photosynthesis, as well as increased oxidative stress, apoptosis levels, and ion transport. Plastic particles seem to negatively impact symbiotic relationships between corals and their microalgae, thereby degrading the entire coral reef ecosystem, but this has not been systematically investigated.…”

Plastic products contribute heavily to anthropogenic pollution of the oceans. Small plastic particles in the micro- and nanoscale ranges have been found in all marine ecosystems, but little is known about their effects upon marine organisms. In this study we examine changes in cell growth, aggregation, and gene expression of two symbiotic dinoflagellates of the family Symbiodiniaceae, Symbiodinium tridacnidorum (clade A3) and Cladocopium sp. (clade C), under exposure to 42-nm polystyrene beads. In laboratory experiments, cell number and aggregation were reduced after 10 days of nanoplastic exposure at 0.01, 0.1, and 10 mg/L concentrations, but no clear correlation with plastic concentration was observed. Genes involved in dynein motor function were upregulated compared to control conditions, while genes related to photosynthesis, mitosis, and intracellular degradation were downregulated. Overall, nanoplastic exposure led to more genes being downregulated than upregulated and the number of genes with altered expression was larger in Cladocopium sp. than in S. tridacnidorum, suggesting different sensitivity to nanoplastic between species. Our data show that nanoplastic inhibits growth and alters aggregation properties of microalgae, which may negatively affect the uptake of these indispensable symbionts by coral reef organisms.

Microplastics (MPs) have become an important concern among scientists and policymakers all around the globe. Despite this, the contribution of MPs to global warming and climate change, a significant aspect of the issue, has been overlooked. Continuous greenhouse gas (GHG) emissions resulting in climate change have long been a major issue with apparent consequences. Climate change and plastic crises are threatening our planet, and the co-occurrence of both would be catastrophic. This article addressed the links between microplastic pollution and climate change; how MPs contribute to climate change by interacting with water, air, and soil; and recommendations to address the issues together. Throughout their lives, plastics emit GHG. MPs in water impede the climate change mitigation potential of the ocean in different ways; they hamper photosynthesis and carbon sequestration by phytoplankton and the Blue Carbon Ecosystem. MPs induce GHG emissions from the soil. Airborne MPs have the potential to aid in cloud formation and interfere with atmospheric cooling. Climate change–induced extreme events redistribute MPs in the environment, causing the pollution to increase vertically and horizontally, which then aggravates the situation in a feedback loop. The evidence acquired in the study implies that MPs and climate change are inextricably linked and that MPs play a vital role in fueling climate change. This bridges the gap between MPs and climate change issues that were previously regarded separately. Due to the linkages between these intertwined challenges, integrated and holistic research and policy measures are required to address both crises concurrently.
