I've heard that there's a lot of pollution in the ocean. Is that true?

Yes, it is true. There are many sources of pollution in the ocean. One of the most common is plastic pollution. Plastic can be found floating in the ocean and can harm marine life by blocking their digestive systems or entangling them in fishing gear. Other types of pollution include oil spills, chemical runoff from land, and agricultural waste. These pollutants can have serious effects on the health of our oceans.
