Population Change Turn up to p136 in Evolving Planet. Death rate has fallen and therefore people are living longer. Why?...

Reduction in death rates Development of modern medicines. This has meant that more and more people are kept alive due to modern practices. Introduction of vaccination and immunisation programmes e.g. smallpox vaccination that helps people to live longer. Cleaner drinking water and better sewage disposal, a lot more people have access to clean drinking water than before. Better healthcare – more doctors, nurses and hospitals, means that people can be treated and not die. More hygienic housing. Better diets, e.g. promoting eating ‘5 a day’

Explain what has happened over time, what factors influence population and what may happen in the future. Over 6 billion people live here and its still rising. Although did you know that it hasn’t always been like this ……. What will happen in the future? Will we be able to feed ourselves if we carry on like this? I’m Mr Pinks and I’m reporting on the growth of …
