Hi Mark,

I'm writing to you from Côn Đảo island, where I'm working as a volunteer for the International Union for Conservation of Nature (IUCN). I have just come here for two days but I have (1) largest global (2) It (3) done so many things. Do you know that IUCN is one of the oldest and organisations? IUCN has worked in Vietnam since the mid-1980s. to protect endangered wild animals, especially the sea turtles in Vietnam. In Côn Đảo island, many sea turtles swim to the islands between the fourth and seventh lunar months and lay their eggs in the sand before returning to the sea. However, the number of sea turtles (4) over the last 30 years because of overfishing, pollution and destruction of nesting beaches. During the days, we have taken part in coastal clean-ups. At night, we have guarded turtle nests, protected eggs (5) poachers and released baby sea turtles back into the ocean early in the morning. It's hard work but it's enjoyable and I've met a lot of great people. The best part about working for IUCN is that I can help endangered animals and still have fun at the same time.

I hope you're having fun, too. See you in a month.
