Microplastics Are Making Photosynthesis Harder for Plants—and That Could Slash Crop Yields, Study Suggests

On average, these little particles could reduce photosynthesis in plants and algae by up to 12 percent, according to the paper

Had to de-sensationalize the title a bit because the results are on the speculative side, but the authors project a 4-13 percent decrease in crop yields, which would be enough to keep the current rate of genetic gain from keeping up with the anticipated impacts of climate change
