The green turtle is listed as endangered by the International Union for the Conservation of Nature. Under the U．S. Endangered Species Act of 1973, the green turtle was listed as threatened except for the breeding populations in Florida and on the Pacific coast of Mexico, where it is listed as endangered.
Green turtles continue to be caught for money by humans, and the destruction and loss of nesting and foraging(觅食)sites is a serious problem. Humans have already caused the decrease of large green turtle populations, including those that once nested in Bermuda and Cayman Islands. The situation of green turtle populations is difficult to determine because of our lack of knowledge about their life cycles. The number of nests in Florida appears to be increasing, but we don't know whether this is due to an increase in the number of nests or because we have started to monitor(监控)nesting beaches more closely.
The green turtle is the largest hardshelled sea turtle. Adults of this species commonly reach 100 cm in length and 150 kg in mass. The average size of a female nesting in Florida is 101.5 cm straight in length, with an average body mass of 136 kg.
Growth rates of green turtles have not been measured under natural conditions. Green turtles grow slowly.
In the southern Bahamas, green turtles grow from 30 to 75 cm in 17 years, and according to Bjorndal and Bolten, growth rates decrease with increasing length. Growth rates measured in green turtles from Florida and Puerto Rico fall within the range of growth rates measured in the southern Bahamas. Based on growth rate studies of wild green turtles, the researchers Balazs, Frazer and Ehrhart estimate the age of sexual maturity(成熟)can range anywhere from 20 to 50 years.

When I was three years old, my parents discovered I was totally deaf. But instead of sending me to a school for the deaf, they decided to “mainstream” me. All of my peers and teachers world have normal hearing.
I was the only deaf child at Blue Creel Elementary School. From almost the first day there, the other kids made fun of me mainly because of my hearing aid and the way I talked. And I also had difficulty with most of my school work.
When the other kids made fun of me, I was sure that I was a bad person. I saw myself as a boy who wasn’t smart enough to keep up with the class.
Mrs. Jordan, my 5th grade teacher, changed all of that with a simple three-word phrase.
One morning, she asked the class a question. I read her lips from my front-row seat and immediately raised my hand because I was sure I had the right answer. But when she called on me, I was afraid. Here was an opportunity to impress the powerful teacher and show her I was worthy of her love. Maybe even impress my classmates a little. I didn’t want to blow it. despite my fears, I took a deep breath and answered Mrs. Jordan’s question.
I will never forget what happened next. Mrs. Jordan enthusiastically slammed （跺动）her right foot on the floor and turned her tight hand around in full circle until it pointed directly at me. With sparking eyes and a wide smile she cried, “THAT’S RIGHT STEPHEN!”
For the first time in my young life, I was a star. I sat a little taller in my chair.
From that day forward, my grades and speech improved greatly. My popularity among my peers increased. It was all because Mrs. Jordan believed in me and wasn’t afraid to express it. “THAT’S RIGHT STEPHEN!”
