A team of environmental researchers, Earth scientists and pollution specialists at Nanjing University, the Chinese Academy of Sciences and colleagues from Germany and the U.S. has found evidence that microplastics have a negative impact on photosynthesis in terrestrial, marine, and freshwater ecosystems.

In their study, in the Proceedings of the National Academy of Sciences, the group conducted a meta-analysis of data from more than 150 studies involving the impact of microplastics on plants.

Prior research has shown that microplastics have made their way to nearly every ecosystem on the planet, and now contaminate plants and animals, including humans. For this new study, the research team wondered if microplastics might have an unknown impact on plants living in the ocean, in fresh water or growing on land, and they conducted a study of prior research to find out.

The team suspected that microplastics might have a direct impact on the ability of plants to engage in photosynthesis. To that end, they searched the literature using an AI app and found 157 studies that mentioned both microplastics and impacts on photosynthesis, which included 3,286 observations.

Combining the results, the researchers calculated that microplastics reduced photosynthetic efficiency across all three plant types by 7% to 12% and caused reductions in production of chlorophyll. Such percentages, they suggest, result in approximately 4% to 14% harvest yield losses of maize, wheat and rice around the globe. They also suggest that microplastics account for up to 7% of losses in global aquatic net primary productivity.

The research team notes that the problem appears to be worsening, which will impact crop production even more. They further suggest that if the problem is not reversed, the result could be a major increase in the number of people at risk of starvation over the next two decades.
