A choropleth map displays numerical data using a color gradient. This kind of map can quickly display how a particular factor—such as population density or per-capita income—varies across regions or countries. Not only are choropleth maps easy to read, but they can be easy to create using Google spreadsheets. We did this to make maps of global urbanization for a new megacities lesson plan we’re working on here at Population Education. You and your students can follow these steps to join us as instant cartographers!
We’ve been told that air pollution, smog, and climate change present major health risks, but do we really know the true human cost? The recent Washington Post article, “Exposure to pollution kills millions of children, WHO reports find,” summarizes two new World Health Organization (WHO) reports that lay out the devastating effect of human-caused pollution on children’s health.
The World of 7 Billion student video contest encourages students to think critically about the challenges facing the planet today and to take that understanding to the next level through problem solving. One component of the video is to offer a sustainable solution to their chosen global challenge. Students take their newfound knowledge and apply STEM principles to design a sustainable solution to the global challenge and in doing so, begin to think like engineers, scientists, and future policy-makers.
In 2010 it was announced that for the first time ever, over half of all people in the world were living in urban areas. Since 2010, the number of city dwellers has continued to soar. In fact, in 2050, it’s predicted that over two-thirds of the global population (that’s almost 7 out of every 10 people) will live in urban areas.
