[00:05.65]Module 5 WORLD POPULATION
[00:10.03]UNIT 1 In the 1800s
[00:13.32]there were only one billion people.
[00:17.68]1 Listen and read. Then say.
[00:22.86]Did you find much information for your project?
[00:27.19]Yes, lots.It's all so interesting.
[00:31.13]I didn't know anything about world population
[00:34.19]before this project.
[00:36.18]What did you find out?
[00:38.28]Well, it's not good news really.
[00:41.82]I was reading about how the population
[00:44.73]of the world is getting bigger and bigger.
[00:47.99]Why is that so bad?
[00:50.26]Because we don't have enough food
[00:52.81]and space for everybody!
[00:55.36]Did you know that by the year 2020
[00:59.29]there could be eight billion people
[01:01.63]in the world?What's the population now?
[01:05.62]There are over six billion now,
[01:08.52]but in the 1800s
[01:10.57]there were only one billion people!
[01:13.53]Wow! Yes, and I found this amazing website.
[01:19.39]You can actually see the population
[01:21.74]increasing on the screen!
[01:23.94]It was horrible! Why!
[01:26.45]Well, it doesn't just tell you
[01:28.83]about the babies being born!
[01:31.74]It also shows you the people who are dying,too.
[01:36.05]They expect millions of people to die
[01:38.94]if we don't have enough food and water.
[01:42.12]Oh, that's awful! I know! Anyway,
[01:46.82]what about your project?
[01:49.00]Did you find all the information you need?
[01:52.01]I think so.
[01:53.20]I'm going to write it up this weekend.
