A sea turtle island nesting site in Australia now has 99% of its young green turtles turning female. The sex is determined by the heat of the nesting beach, so hotter seas, air, and sand lead to dramatic changes in the ratio of females to males. We need to keep trees along beaches to shade them, and we need to fight against the oil and coal companies that are causing global warming. We make a turtle design on totebags, so you can replace plastic shopping bags that choke turtles and birds. Here is a link to the turtle totebag and t-shirts.   https://news.nationalgeographic.com/2018/01/australia-green-sea-turtles-turning-female-climate-change-raine-island-sex-temperature   https://www.nytimes.com/2018/01/10/science/female-sea-turtles-global-warming.html
