Microplastics (MPs) pollution has emerged as one of the world’s most serious environmental issues, with harmful consequences for ecosystems and human health. One proposed solution to their accumulation in environment is replacement nondegradable plastics biodegradable ones. However, due lack true biodegradability some ecosystems, they also give rise microplastics (BioMPs) that negatively impact different living organisms. This review summarizes current literature on BioMPs organisms—higher plants fish—relevant food chain. Concerning higher plants, adverse effects seed germination, plant biomass growth, penetration nutrients through roots, oxidative stress, changes soil properties, all leading reduced agricultural yield, have been critically discussed. fish, it are more likely be ingested than nonbiodegradable ones accumulate animal’s body, impaired skeletal development, behavioral changes. Therefore, based reviewed pioneering literature, seem a new threat health rather an effective counteract MP pollution, even if knowledge gaps this field highlight need additional rigorous investigations understand potential risks associated BioMPs.
