A new study published in Current Biology has found a major shift in the gender ratio of green sea turtles around Australia’s Great Barrier Reef, according to VOA News. The results of this study indicate that 99 percent of sea turtles born in the northern part of the reef and 87 percent of adult sea turtles around the Great Barrier Reef are female, according to the New York Times. While this topic has been studied previously, the enormity of the situation, as well as the rapid progression, was unknown to researchers.
