<human>:  How are shark populations affected by climate change?
<bot>: Shark populations are highly affected by climate change as warmer ocean temperatures can lead to drastic shifts in their habitats, causing species to relocate and impacting their food sources. Warmer ocean temperatures can also lead to higher levels of oxygen depletion and decreasing prey abundance, putting additional stress on already vulnerable species. Additionally, ocean acidification associated with climate change can disrupt the balance of the oceanic food webs, and increased ocean traffic brings higher risks of collisions with ships and other vessels.
