Green Turtles Need Your Help




There are many different types of turtles, but green turtles are one of the most endangered species. My own experience with Green Turtles was snorkeling with two of them recently on one of the Hawaiian islands, Oahu. It was really unique to swim with these gentle giants. Another name for green turtles is “Chelonia Mydas.” Green turtles are green because of the color of the fat under their shells. Green turtles are herbivores and eat nine types of allege and seagrass. Young turtles have been known to eat sponges, seaweed, and jellyfish. Green turtles return to the beaches where they were born to deposit 100-110 eggs in a clutch at a time and do not breed every year. There are only about 800 green turtles living today.

In the nineteenth and early twentieth century, green turtles were used as a source of food, tools, and ornaments by early Hawaiians. Green turtles are also endangered because of poaching, artificial lighting, beach nourishment (disturbing nests), pollution, drowning in fishermen’s nets, and predators of both the turtles and their eggs. But the number one killer of green turtles is fibropapilloma tumors. Fibropapilloma tumors grow on a turtle until it is debilitated. Baby turtles find their way to the ocean by the light reflected off of it. Artificial lighting from street lamps, buildings, and beachfront properties has a disorienting effect on baby turtles. Some turtles abort nesting in lighted areas and with fewer and fewer beaches undisturbed, they have less places to lay their eggs.

Big Bears in Big Danger--The Giant Panda



In this article you will find information about one of the world's most endangered bears, the Giant Panda. They live in the Shaanxi, Sichuan, and Gansu provinces of China. They are about 1,600 Giant Pandas living today. More than 160 pandas live in captivity. The Giant Panda’s diet is about 99% bamboo and 1% fruit and meat in the wild. They will eat roots and rodents and even some carion. They are naturally carnivores, but have adapted to eat mostly bamboo. In captivity their diet consists of bamboo, sugarcane, rice gruel, high-fiber biscuits, apples, carrots and sweet potatoes. Giant Pandas need to eat 12 to 32 kilograms of bamboo a day to meet their energy standards.

They are mainly endangered because of habitat loss, hunting and low reproductive rates. Since they eat so much bamboo, they can only live in areas of the wild where it grows. As people move in, the pandas have less and less place to find their food. Giant Pandas often live alone, so they don't mate very often and usually one of the babies doesn't survive. One way you can help the Giant Panda is by learning about them and donating to groups that support and protect these big bears.
