[00:18.45]Overpopulation
[00:21.07]Have you notice that there are more
[00:23.34]people in towns and cities these days?
[00:26.96]Are there more children in your school
[00:29.61]or in your hometown?
[00:31.95]Maybe you haven't noticed it,
[00:34.69]but the population on the Earth
[00:36.35]is growing very fast.
[00:38.60]In fact, it is growing too fast!
[00:42.33]When your grandparents were children,
[00:45.10]there were only about 2.5 billion people
[00:48.97]on this planet.
[00:50.90]Now, there are over six billion,
[00:54.38]Every year, the population increases
[00:57.56]by another 80 million.If this continues,
[01:01.59]by the time you are grandparents,
[01:04.83]there will be over 14 billion people
[01:07.64]in the world!This increase in population makes
[01:12.27]all the problems in the world much worse.
[01:16.38]This is because everything is connected.
[01:19.63]The more people there are,
[01:21.56]the more resources we need.
