Part of a food science lecture on fashions in food

Now listen and answer questions 26 to 30. So what are we going to do our assignment on? I'll tell you what. One of the possibilities we haven't discussed is urbanisation. And now over half the world's population lives in cities. That's really important. OK, good idea, Rosie. Let's do that. I love living in a big city, but of course there are problems. Things like theft and robbery? Yes, but where I come from, that's linked to another more serious issue, which is that a lot of people don't have jobs. That's getting worse and worse. And we also still have quite a lot of people who are homeless, though that's not quite so bad as it was. It'd be nice to talk about some positive developments, like some of the new developments on the outskirts of cities. Yeah they opened some massive new shopping centres outside my city Yeah the same with mine but it meant a lot of the shops in the city centre are closing down But the outskirts are ideal for buildings that need a lot of space like for conferences They've opened a couple of big ones. Yes, we've got some too. It'd be nicer to have more facilities for things like football too, but that's not happening where I live. Same in my area. We could include something about developing disused industrial sites. It seems like a good idea, because you're not doing any harm to the natural environment. Yeah, but aren't the buildings architecturally significant? Not really. And what people forget is that they often used quite dangerous materials, chemicals and things, which haven't been properly cleared away, so the whole site has to be made safe. Hmm, that can't be cheap, and I bet it's often not budgeted for. You're right. Have you read about Mazdar City? In Abu Dhabi? Yes. It was designed to be a green city, wasn't it? That might be a good example of a city which set out to depend entirely on renewable energy. Yes, we should say something about that. It was designed to be totally pedestrianised too wasn it With the transport underground Yes and they had big plans for recycling to reduce waste to the lowest possible level But let stick to talking about power sources Then there's that eco-town in England, Greenhill Abbots. It's set out to conform to the usual principles, sustainability and so on. A lot of people were against it at first. They said the plans were unrealistic. I'm not sure how far they've got with it. I'll check. Right. So it looks as if we have a sort of plan. That is the end of part three. You now have 30 seconds to check your answers to part three. Thank you Part 4 You will hear part of a food science lecture on fashions in food. First, you have some time to look at questions 31 to 40. Thank you.
