A new study has found that the world's green sea turtles are increasingly feminized  Experts estimate that by 2100, about 93 percent of newborn green sea turtles will be female  Research has shown that the main factor in determining the sex of green sea turtles is the temperature of the sand surrounding the turtles when they hatch
If the temperature of the sand is between 28 and 30 degrees, the proportion of green sea turtles hatching is about the same; if the temperature is higher than this range, the green sea turtles hatching are mostly female, on the contrary, most of the green turtles are male
Greenhouse effect will cause global warming problem to become more and more serious
