The passage discusses the impact of climate change on the world's oceans and the potential consequences for marine life. The author argues that rising temperatures and increasing acidity levels are already having a significant impact on the ocean ecosystem, with potentially devastating consequences for species that rely on it for survival.

The first part of the passage focuses on the effects of rising temperatures on the ocean. The author notes that warmer waters can lead to coral bleaching, which occurs when the symbiotic relationship between coral and algae breaks down. This can have a ripple effect throughout the food chain, as many species rely on coral reefs for food and shelter. The author also notes that warmer waters can lead to the expansion of harmful algal blooms, which can be toxic to marine life and humans alike.

The second part of the passage focuses on the impact of increasing acidity levels on the ocean. The author notes that as carbon dioxide levels in the atmosphere rise, more of it is absorbed by the ocean, leading to increased acidity levels. This can have a significant impact on marine life, particularly on species that rely on calcium carbonate to build their shells or skeletons. The author notes that some species may be able to adapt to these changes, but others may not, leading to a decline in biodiversity.

Overall, the author argues that climate change is having a significant impact on the world's oceans, and that urgent action is needed to mitigate its effects. The author suggests that reducing carbon emissions is key to addressing this issue, but also notes that other measures, such as protecting marine habitats and reducing overfishing, may also be necessary. Ultimately, the author argues that the fate of the world's oceans is closely tied to the fate of humanity, and that we must take action now to ensure a sustainable future for both.
