Malthus’ theory about overpopulation, written in ‘An Essay on the Principle of Population’ (1798), might be familiar to you. If not, or if you just need a reminder, look at the graphs and explanations on the link below. This is a very basic guide to Malthus, but it’s a good start:

In the absence of positive checks (e.g. disease, famine) and preventative checks (e.g. sexual abstinence), Malthus thought that population could grow exponentially and outstrip food supply, which would grow at a slower rate. At this point, there wouldn’t be enough food to feed the high population.
Task 1:
1. What do you think of Malthus’ theory? Can you spot any flaws?
2. Do some further research about how popular Malthus’ theory has become. The below article is a good place to start; Sir David Attenborough has argued that we should control population to prevent the strain on resources. Can you also think of any examples of population control; perhaps start with a bit of research on China’s one-child policy?
Task 2:
There is a report here which lists the challenges that overpopulation can cause:

Remember to maintain a critical eye. In the case studies on the link above, do you think that overpopulation is the only source of problems?
