The correct answer is:
d. microplastics
Microplastics are tiny pieces of plastic that are less than five millimeters in size. They come from larger plastic items that have broken down over time or from microbeads used in cosmetics and personal care products. These microplastics can contaminate water sources like rivers, oceans, and lakes, posing a threat to marine life and potentially entering the food chain when consumed by fish and other aquatic organisms. Proper waste management and reducing the use of single-use plastics are important steps to help prevent further contamination of our waters.
