Underwater forest

Several years ago, scuba diver Chas Broughton discovered an underwater forest of massive ancient cypress trees. Located twenty kilometres from the coast of Alabama, in the Gulf of Mexico, it is home for thousands of sea animals. Chas told a local journalist about the discovery, but they kept it secret until 2004, when Hurricane Ivan uncovered some of the trees. Then scientists started exploring the area. They have suggested that the forest is more than 50,000 years old. In the past, the ocean level in the area was 125 metres lower than today, but when it rose, the water swallowed the trees up. The forest is so unique that conservationists are now working to make it a marine protected area.

Last week I took part in an unusual survey. A psychologist invited

forty-four families and asked us different questions about eatinghabits now and in the past. She wanted to find out why fathers give children less healthy food than mothers. Strange, isn’t it? But it’s true in my family. When my mum isn’t at home for dinner, Dad orders a pizza. Mum doesn’t accept unhealthy food because she feels responsible for what we eat. Dad cares more about my education or hobbies. According to the survey, in most

families the situation was and is similar. Teenagers observe their

parents and learn how to behave in the future. My parents used to

observe their parents and now I am observing them.
