Developments in science have affected populations in a number of ways. Let’s look at how science helped to…
- control diseases and infection
- improve sanitation and access to clean water
- develop canned food and refrigeration
What has science helped us understand about the causes and effects of diseases? How do these discoveries benefit us?
Science has helped us understand what causes certain diseases and how the diseases affect our bodies. This has made it easier to treat and control diseases.
What important scientific developments helped control diseases?
Vaccinations and the discovery of certain medicinal drugs.
What do vaccinations do? What happens when you give children vaccinations?

What is part of people’s indigenous knowledge?
All communities have knowledge about certain herbs and plants that people use to heal and treat illnesses.
How are many serious diseases spread?
Many serious diseases are spread by people drinking dirty water.

Science has helped people to develop ways of purifying water to make it safe to drink.
How has supplying people with clean water helped?
Supplying people with clean water as helped to reduce death rates, especially among children.
What does the sanitation and the development of better toilets reduce?
