Global plastic pollution remains a significant threat to marine and terrestrial ecosystems, with an estimated 11 million tons of plastic waste entering the oceans annually. This scale of pollution is driven by massive waste accumulations and an annual production rate of approximately 450 million tons. Scientific research has focused on the ‘plastisphere,’ an anthropogenic ecosystem formed by microbial communities—including bacteria, fungi, and viruses—that colonize plastic debris. Originally identified in 2013 in the North Atlantic, these communities transform artificial plastic surfaces into new habitats. This process involves the adhesion of microorganisms to polymers and the production of extracellular polymeric substances, which facilitates the establishment of diverse organisms such as cyanobacteria and various eukaryotic predators and consumers. There are concerns that these unique habitats may facilitate the spread of antibiotic-resistant genes. In response to these environmental challenges, circular economy models are emerging. Initiatives such as those by Tabi Clean utilize biodegradable effervescent tablets and reusable containers to reduce the consumption of single-use plastic bottles. A recent international review by The Lancet Countdown on Health and Plastics has highlighted the escalating crisis, noting that approximately 50 million tons of plastic waste impact the environment annually. Since 1950, plastic production has increased more than 200-fold and is projected to nearly triple by 2060. Currently, over 98% of plastics are derived from fossil fuels, contributing to the release of 2 billion tons of CO2 per year. With global recycling rates remaining below 10%, much of the 8 billion tons of existing plastic waste remains in landfills, oceans, or is subject to open-air incineration. The plastisphere continues to evolve as microorganisms like microalgae colonize fragments, creating active habitats that can transport species across the globe via ocean currents.
