Q

Why has population continued to increase? (6)

A

Mainly due to a decline in death and infant mortality rates due to:

1) Development of modern medicines, modern practices are better so people are kept alive longer.
2) Introduction or vaccination and immunisation programmes that help people to live longer e.g. smallpox
3) Improved access to cleaner drinking water and better sewage disposal.
4) Better healthcare - people are looked after and treated whey they are unwell so they survive longer.
5) Improved hygiene and better housing.
6) Better diets, e.g. promoting eating 5 a day.
