Overpopulation

We are having a fascinating inquiry into our world's population. We are looking at a number of graphs, videos, and articles to help us get our heads around this issue.

There are lots of surprising things being learnt such as the average family size dropping world wide from 7 - 2.5 in 50 years. That it took thousands of years for the worlds population to get to 1 billion, but then only another 200 years to get to our current 7 billion (as a result of the industrial revolution). By the end of this century it will peak at 11 billion. However, the population of children has already peaked at 2 billion.

We are looking at what the effects will be and what needs to change in order for us to survive the increase. Some information shows some people are really worried about the earths future where as others are more positive about our ability to cope. The students are writing articles about what will need to change for our earth to survive overpopulation.

Here are some interesting sites and videos:
