What elements threaten our marine ecosystem?

What elements threaten our marine ecosystem?

• A. Increased biodiversity.
• B. Non-native species.
• C. Oil spills.
• D. Climate stability.

Answer: (C)

The correct answer highlights one of the significant threats to marine ecosystems. Oil spills have devastating effects on marine life and habitats. When oil is released into the ocean, it creates a film on the water's surface that can harm aquatic organisms, disrupt food chains, and damage essential habitats such as coral reefs and mangroves. The toxicity of the oil can lead to long-term health issues for marine species and can also impact human activities like fishing and tourism. Recovery from oil spills can take years, if not decades, making this threat particularly critical for marine ecosystems. In contrast, increased biodiversity is generally seen as a positive factor that enhances the resilience of ecosystems. Non-native species may pose a threat by disrupting local ecosystems, but they are not as immediately damaging as the acute effects of oil spills. Lastly, climate stability is beneficial for marine ecosystems; disruptions in climate patterns typically create adverse conditions for marine life. Therefore, oil spills stand out as a significant and harmful element threatening marine ecosystems.
