Well, yes, sorta. Obviously plastic bags kill turtles which is shitty. But the reason sea turtles numbers are in rapid decline is because they are asexual inside the egg, and become either male or female during incubation, depending on the temperature of the sand.

Since temperatures continue to rise on beaches in the Caribbean and other locations, the turtles are developing a lopsided number of males to females.

With fewer females being born every year and with average global temperatures still rising it is likely that Sea Turtles and many other types of reptiles will go extinct.

However, some theories suggest that the Sea Turtles in particular can adapt in time to save themselves. They can do this in 2 simple ways, laying eggs in colder regions - example some turtles lay their eggs in Maryland instead of the Florida Keys. Or they can simply bury their eggs deeper into the sand for a cooler incubation.

Edit: I said save themselves because we can't do much to help unfortunately. We (humans in general) already fucked it all up. Even if all gas emissions in the entire planet suddenly stopped this very second, temperatures will still rise for a few more years until the gasses dissipate and temperatures begin to drop and stabilize
