Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms.
These data were used to relate the decline of the sex ratios of sea turtles in the North East Caribbean and climate change. The species of sea turtles include Dermochelys coriacea, Chelonia myads, and Eretmochelys imbricata. Extinction is a risk for these species as the sex ratio is being afflicted causing a higher female to male ratio.
It is likely that climate change will outpace the ability of many TSD animals to adapt, [44] [45] and many will likely go extinct. However, there is evidence that during climatic extremes, changes in the sex determining mechanism itself (to GSD) are selected for, particularly in the highly-mutable turtles. [ 46 ]

Sea turtles need to reach the surface to breathe, and therefore many drown once caught. Loggerhead and hawksbill turtles are particularly vulnerable. Nearly all species of sea turtle are classified as Endangered. They are killed for their eggs, meat, skin and shells. They also face habitat destruction. Climate change has an impact on turtle ...
Loggerhead sea turtle escapes from fishing net through a turtle excluder device (TED) Threats to sea turtles are numerous and have caused many sea turtle species to be endangered. Of the seven extant species of sea turtles, six in the family Cheloniidae and one in the family Dermochelyidae, all are listed on the IUCN Red List of Endangered ...
Climate change is driving extreme weather. By all accounts, the last few years have been brutal for the climate — and for the humans and other living things within it. Around the globe, heat ...
Studies have shown that climate [157] change in the world is making sea turtles gender change. The study that was in January 2018 Current Biology "Environmental Warning and Feminization of One of the Largest Sea Turtle Populations in the World", showed how baby sea turtles were being born female a lot more than being born male.
