The impact of ocean warming on marine biodiversity is profound as it alters habitat conditions, affecting species distribution, reproductive patterns, and ecosystem dynamics. Warmer waters can lead to coral bleaching, shifts in fish populations, and disrupt marine food webs. Additionally, increased temperatures can result in deoxygenation, further stressing marine species. Endangered habitats, like coral reefs, are particularly vulnerable. Understanding these impacts is crucial for developing conservation strategies that protect marine biodiversity and enhance the resilience of ocean ecosystems in the face of climate change.
