Well as I'm sure you know we live in a society greatly impacted by technology and because so everything important usually ends up on the internet, the dissemination of news helps activists and the regular joe, educate themselves.

>> Anthropology: "is the study of humanity through the application of biology, cultural studies, archaeology, linguistics, and other social sciences."

Before you begin writing about each of the topics write the definitions. Maybe even add names of people who discovered it. Add interesting facts. When you find stuff to write about after doing research your paragraphs (if you're doing an essay) quickly fill up and you overall have more to talk about.
Hope this helped.
