Next year she wants to go to University to study Spanish, but now she is living in Belize(Белиз-небольшоегосударство). Pauline says, “I’m working with other people here to protect the coral reefs (коралловыерифы) in the sea near Belize. The reefs here are beautiful, but if the sea water is very polluted, the coral dies. I’m helping to do research on the coral and the fish that live around the reefs. All over the world, coral reefs are dying. We need to do something about the problem before it’s too late. I’m staying with a family here and I help with the cooking and the cleaning. I don’t get any money, but that’s OK. I love my work here, and I’m learning a lot about the people of Belize –and myself! When I finish my work, I want to stay here for another three months.
