Plastic pollution is one of the world's most pressing environmental challenges. A large portion of the 400 million tons of plastic produced annually ends up in landfills or the ocean. Unlike organic waste, plastic never decomposes. Instead, it breaks down into tiny pieces called microplastics. These particles contaminate water, soil, and air, harming marine life, livestock, and even humans.
