Frequently Asked Questions
What are the major threats to coral reef ecosystems today?
The major threats to coral reef ecosystems include climate change, ocean acidification, overfishing, pollution, and habitat destruction. These factors lead to coral bleaching, loss of biodiversity, and degradation of reef structures.
How does plastic pollution impact marine life?
Plastic pollution impacts marine life through ingestion and entanglement. Marine animals often mistake plastic for food, leading to malnutrition or death. Additionally, microplastics can accumulate in the food chain, affecting various species and ecosystems.
What role do marine microorganisms play in ocean ecosystems?
Marine microorganisms, such as phytoplankton and bacteria, play crucial roles in ocean ecosystems. They are primary producers, forming the base of the food web, and contribute to nutrient cycling, carbon sequestration, and oxygen production in the ocean.
What are the effects of ocean acidification on marine organisms?
Ocean acidification affects marine organisms by reducing the availability of carbonate ions, which are essential for calcifying species like corals and shellfish. This can lead to weakened shells, reduced growth rates, and increased vulnerability to predation and disease.
How can marine protected areas (MPAs) contribute to ocean conservation?
Marine protected areas (MPAs) contribute to ocean conservation by preserving critical habitats, enhancing biodiversity, and allowing ecosystems to recover from overfishing and pollution. They also provide opportunities for research and sustainable tourism.
