What we have long called a pollution problem may in fact be a delivery system — microplastics, it now appears, do not merely contaminate environments but actively transport toxic chemicals, pathogens, and antibiotic resistance genes across ecosystems, acting as mobile platforms that connect and amplify threats far beyond their own physical presence. Researchers from Jiangxi Agricultural University, publishing in Energy & Environment Nexus, have reframed the microplastic crisis not as a story of inert debris but of dynamic ecological actors, small enough to cross biological membranes and persis
