    The Great Migration: Crash Course Black American History #24

    In 1910, 90% of Black Americans lived in the South. By 1940, around 1.5 million Black Americans had left their homes, and 77% lived in the South. By 1970, 52% of Black Americans remained in the South. People moved away for many reasons, including increased opportunity in the more industrial North and West. They sought a relatively safer life away from the lynchings and violence that were concentrated in the South. This Great Migration shaped 20th-century America in countless ways, but we're going to try to count some of them in this video.

    Climate Change, Chaos, and The Little Ice Age: Crash Course World History #206

    In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and the weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

    The War on Drugs: Crash Course Black American History #42

    The War on Drugs is a decades-long United States policy intended to curb illegal drug use and trafficking. Long story short: it has not worked to reduce drug use or trade, and the policy has had devastating effects, especially on communities of color. Today we'll talk about the history of the War on Drugs, what it was trying to accomplish, and how it contributed to the US as a carceral state and the nation that imprisons more of its population than any country in the world.

Broadly, public health is an approach to preventing disease, prolonging life, and promoting health for everyone.

    What is Public Health? Crash Course Public Health #1

    We often think of health as a self-centric phenomenon that begins and ends with "me", but as we'll explore throughout this series our personal health is just one plot line in a rich story of evolving research and policies that make up the world of public health. So what is public health anyway? Well, public health is an approach to preventing disease, prolonging life, and promoting health for literally everyone. It is a money-saving, life-extending, world-bettering cheat code for improving the world, so we'll spend the rest of this series examining how and where it is working, where it isn't working, and how so much of our health is influenced by the world around us.

    How Populations Grow and Change: Crash Course Geography #33

    Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are more elderly people who need care than there are healthcare workers, or even be concerned about how many people are necessary to carry on other aspects of culture. Today, we'll discuss Malthusian and Boserup predictions on the planet's carrying capacity and take a close look at a popular demography tool geographers use to predict population change: the Demographic Transition Model or DTM.

    Jesse Jackson: Crash Course Black American History #44

    Today, Clint Smith is teaching you about the Civil Rights activist and Icon, Reverend Jesse Jackson. Jackson began his career working with Martin Luther King in the 1960s, and in the 1970s he founded PUSH, an organization to advance the cause of urban, poor, and predominantly Black communities. Jackson ran for president of the United States in 1984 and 1988, and founded another organization, the Rainbow Coalition. Jackson has worked for decades for the cause of Civil Rights and his long career has served as a bridge from the work of the 1960s to the movement for Black lives today. Clint's book, How the Word is Passed is available now! https://bookshop.org/books/how-the-word-is-passed-a-reckoning-with-the-history-of-slavery-across-america/9780316492935 Sources: Marshall Frady, Jesse: The Life and Pilgrimage of Jesse Jackson (New York: Random House, 1996).
