Pollution from industrial and agricultural activities can:

The correct answer is: d) All of the above

Pollution from industrial and agricultural activities can harm fish populations, contaminate seafood, and degrade marine habitats.

• Harm fish populations: Pollution can harm fish populations in a number of ways. For example, pollution can kill fish directly, or it can make fish sick, which can make them more susceptible to predators or disease. Pollution can also damage fish habitats, making it difficult for fish to find food or reproduce.
• Contaminate seafood: Pollution can contaminate seafood in a number of ways. For example, pollution can cause fish to accumulate toxins in their bodies, which can then be passed on to humans who eat the fish. Pollution can also make seafood unsafe to eat by causing it to spoil or become contaminated with harmful bacteria.
• Degrade marine habitats: Pollution can degrade marine habitats in a number of ways. For example, pollution can smother coral reefs, kill seagrass beds, and pollute beaches. Pollution can also make marine habitats more acidic, which can harm marine life.

Pollution from industrial and agricultural activities is a major threat to marine ecosystems. It is important to take steps to reduce pollution and protect marine life.
