Read the following passage and answer the question below. Plastic pollution has become one of the most visible and pervasive environmental problems of the modern era, with millions of tons of plastic waste entering the world's oceans every year. Unlike organic materials, plastic does not fully biodegrade; instead, it breaks down into smaller fragments called microplastics, which can persist in the environment for hundreds of years. These microplastics have been found in even the most remote parts of the ocean, as well as in the tissues of marine animals that mistake plastic fragments for food. Ingested plastic can cause injury, starvation, or death in marine species, and there is growing concern about the potential effects of microplastics entering the human food chain through seafood consumption. In response, many countries have introduced bans on single-use plastic items such as bags and straws, while researchers continue developing biodegradable alternatives. Public awareness campaigns have also encouraged individuals to reduce plastic consumption and improve recycling habits. Question: According to the passage, what are microplastics?
- A. Chemicals used to manufacture plastic
- B. A type of biodegradable packaging
- C. Small fragments that plastic breaks down into over time ✓
- D. A species of marine algae
Correct answer
C. Small fragments that plastic breaks down into over time
Explanation
The passage defines microplastics as the small fragments plastic breaks down into since it does not fully biodegrade.
