4. at Comprehension: Read the passage carefully. Answer the questions given below. Plastic pollution has emerged as a pervasive environmental crisis affecting terrestrial and marine ecosystems globally. Since mass production began in the mid-twentieth century, billions of tons of plastic have been manufactured, much of which persists in the environment for hundreds of years due to its resistance to degradation. Ocean currents concentrate plastic debris into vast gyres, creating zones where floating waste outnumbers marine life. Microplastics, tiny fragments resulting from the breakdown of larger items, have infiltrated food chains and been detected in organisms from plankton to apex predators, including humans. The economic convenience and versatility of plastics have made them ubiquitous in modern life, complicating efforts to reduce consumption. Recycling programs exist but process only a small fraction of plastic waste, with most ending up in landfills or natural environments. Addressing plastic pollution requires systemic changes including reducing single-use products, developing biodegradable alternatives, improving waste management infrastructure, and fostering consumer awareness about environmental impacts.
