The ABC of Ecology.

Аудиозапись номер девятнадцать.

Listen to the dialogue and complete the sentences in your workbook.

Speaker 1: Brian, dear, I want to say how much I've enjoyed your presentation today. It was terrific. Are you really so much interested in ecology?

Brian: Yes, I am. The more I study the subject, the more interested I get.

Speaker 1: Okay, but why the ecology of the oceans?

Brian: The world oceans still keep their mysteries from us. And they are very important for the future of the planet.

Speaker 1: What mysteries are you talking about?

Brian: Let me give you an example. What do you know about the blue whale?

Speaker 1: The blue whale? I've never heard of it. Is it really blue?

Brian: Yes, this animal was named so for its bluish gray color. It looks blue under the water and gray on the surface.

Speaker 1: So, what is so special about this species?

Brian: It's the largest animal that has lived on our planet. Its heart is as large as a car. Its tongue alone can weigh as much as an elephant.

Speaker 1: You don't say so. It's amazing!

Brian: Blue whales can talk with each other and their calls are really loud. They are among the world's longest-lived animals. They can live to be about one hundred and ten years old.

Speaker 1: You seem to know so much about the blue whale, but why have you decided to choose them?

Brian: They are one of the most endangered species in the world. Only a few thousand blue whales swim in the world's oceans. People have hunted them for many years, and now they're nearly extinct. Some time ago, the blue whale became a protected species. Today, they seem to be growing in numbers.

Speaker 1: It's good news!

Brian: Yes, you're right. But scientists say they're not out of danger yet.
