Which elements do NOT threaten our marine ecosystem?

Increased biodiversity is a positive factor in marine ecosystems. It generally enhances the resilience and stability of the ecosystem, enabling it to better withstand environmental changes and anthropogenic pressures. Higher biodiversity can lead to more complex interactions among species, which often results in improved ecosystem services such as nutrient cycling, water purification, and overall health of the marine environment.

In contrast, non-native species often disrupt local ecosystems by outcompeting native species, leading to declines in biodiversity. Oil spills introduce toxic substances into marine environments, causing significant harm to marine life. Erosion, depending on its cause and intensity, can lead to habitat destruction and negatively impact organisms that rely on stable environments. This demonstrates why increased biodiversity does not threaten marine ecosystems; instead, it plays a critical role in maintaining their health and functionality.
