Learning Intentions

By the end of this lesson, you should be able to:

Identify the key issues arising from a large population.
Describe and explain the spatial variations of these impacts on the earth's capacity to provide basic human needs to everyone on the planet.

Making predictions is a vital geographical tool. Geographers are often employed in positions that require them to use their knowledge and understanding of geographical phenomena, analyse existing data patterns and trends, and use research methods, to identify potential problems that might occur and to offer realistic, sustainable solutions.

Such careers include urban planning, meteorologist, environmental consultant, transportation planning and design, conservation officer, volcanologist, and geoscientist..... to name a few!

Task 1 - fast thinking exercise - 5 minutes

Imagine this scenario - overnight there are twice as many people in the world. Working with a partner, make a list of 10 of the most major immediate impacts of such a population increase.

Hint - think of vital resources that people use on a daily basis that have an impact on their health and wellbeing as well as the main ways that people would be impacted immediately.

Task 2 - video

a) As you watch, tick off any of the things on your list that you had identified that appear in the video and make a list of 5 impacts not on your list.

b) Discuss - Who and where are those people who are impacted the most? Why?
