Countries have different policies regarding whether it should be mandatory to vaccinate children. Have a look at the map below and discuss what you see with your teacher.

Visuals: Falling sperm count

In 2017, Shanna Swan and Hagai Levine, along with six other researchers, estimated the average sperm count for 43,000 men in 55 countries across the world. The data, from 185 previously published studies, suggest that sperm counts fell by about 25% between 1973 and 2011. They found that sperm counts had in fact fallen by about 50% in Western countries over the period. Although the data were less plentiful, similar trends were observed in developing countries, too.

Visuals: language speed & density

According to The Economist, languages face a trade-off between complexity and speed. Those packed with information are spoken more slowly, while simpler ones are spoken faster. As a result, most languages are equally efficient at conveying information.

For instance, a Japanese translation of this text would be longer and a Thai one would be shorter, but readers would finish reading it at about the same time.
