Climate change could wipe out marine life due to lack of dissolved oxygen

The thing about climate change is that we usually only see one side of it: the changing weather pattern side, or the increase in global temperature side. What we don’t see is the side about the destruction of natural habitats, specifically of those animals in the poles.

Other animals greatly affected by global warming are corals, fish, and crustaceans.

According to Curtis Deutsch, University of Washington oceanographer, an increase of temperature would mean warmer ocean water, increasing the metabolic rates of ocean creatures. This isn’t a problem in itself, but warmer water holds less oxygen, forcing the animals to find cooler areas. “As habitat shrinks, populations are also likely to shrink. In the extreme, it leads to extinction, as we see with habitat destruction in terrestrial ecosystems.”

A species moving to another environment will cause them to meet new conditions such as predators and new prey.

A study that looked at the world’s largest group of coral reefs—the staghorn corals—that are the dominant coral species in reefs of the Indo-Pacific region and can also be found in the Caribbean are dangerously susceptible to coral bleaching.

Coral bleaching is when high temperatures force corals to expel the algae in their tissues. This gives them a white color and, essentially, kills them.

However, cooler water is not an option for corals since they need sunlight, which is usually only abundantly found near the equator.
