Reading Passage
Climate change is a pressing global issue that has far-reaching consequences, particularly on marine ecosystems. Rising sea temperatures, ocean acidification, and changing currents are just a few examples of how climate change is affecting marine life. One significant impact is the bleaching of coral reefs due to increased water temperatures. Coral reefs are vital ecosystems that support a diverse range of marine species, and their decline has ripple effects throughout the food chain. Additionally, rising ocean acidity poses a threat to shell-forming organisms like mollusks and crustaceans, impacting their ability to build and maintain their shells. These changes disrupt the delicate balance of marine ecosystems, leading to declines in biodiversity and productivity. Understanding the interconnected nature of marine life and the environment is crucial for mitigating the effects of climate change.
