What kind of science do you wish people understood? What science do people need to understand in order to make the world a better place?
Obviously Epidemiology & the spread of infectious diseases, ecology, and climate science are right up there.
I'd add food science - by which I mean how food cooks, how/when bacteria grow in food, what happens to different foods when you refrigerate or freeze them, or expose them to oxygen, and nutritrion,
as well as health - what does your body need to be healthy, how do you know when you're getting sick, what do we know and not know about how the body works.
I'd add the psychology of marketing, of sleep, and of learning.
Also the physics of motion - stopping distance, friction, water, etc.
