How do ideas, animals, and diseases spread around the globe?

Explanation:

Ideas spread from person to person. If one man has an idea and tells another man his idea, the other man will tell another this idea and the process will go on, every person the idea comes across will pass it on to another. Diseases spread through animals, plants and humans. Humans carry diseases sometimes without being affected or knowing of them and pass it to an animal or another human. Animals are spread around the globe by migration pretty much over time. When their habitat is no longer safe or reliable they move on and will migrate to a different and establish their new one. But in other cases some animals spread because either they are captured by humans and released into the wild or they break from their pack/herd and start a new one.

I believe, the answer could be that the way they spread is by focusing attention on the human causes of infectious disease epidemics, such as land-use change, urbanization and industrialized food production, “Outbreak” teaches the modern lesson that human, animal and environmental health are all critically linked. Viruses only replicate inside living organisms, and adapt rapidly to a new host. One infection can spread to epidemic proportions in a matter of days.
