Obesity is a growing problem around the world.

Obesity is defined as having a body mass index (BMI) of over 30. BMI is used to determine whether you are in a healthy weight range for your height. For instance, a person who is 180cm (5ft 11in) and 97kg (213lb) has a BMI of 29.7. 

The rate of obesity varies greatly around the world. Please have a look at the map below and discuss what you see with your teacher.

People today are taller, on average, than their ancestors 100 years ago. This is true for every country in the world.

Over 900 animal species have gone extinct since the year 1500, and many more are threatened with extinction.

Extinction means that an entire animal species dies. For instance, the Dodo bird, a flightless bird that used to live on the island of Mauritius, went extinct in the 18th century because of overhunting by humans.

For years researchers argued about the "Nature vs Nurture" question. Is a person talented because they were born that way, or did people and circumstances in their environment cause them to develop certain skills?

While this question stays open, there is little doubt that living conditions do matter. Could Steve Jobs have created Apple if he was born in a village in Africa? How much new technology or how many groundbreaking discoveries are we losing because talented children in poor areas don't have access to adequate education?

European football (soccer) has a history of racism. Recently, there has been a rise in racist comments from fans against players of color. Many football clubs are taking action against it. There are even projects involving computer- and A.I.-assisted technology to pinpoint racist fans.

But fans aren't just shouting abuse at matches; they're using social media as well. A 2021 study of online messages against the U.K's Premier League players found more than 3,000 abusive messages, 56% of which were racist.

So, how are social media platforms responding? Are they doing enough? The graph below shows what fans across Europe think.

Even though punishment by death has been abolished in many places globally, there are still fifty-five countries that practice the death penalty, with the USA and China being among them. So what are the arguments for and against the death penalty?

Music can connect people everywhere. It can cross languages, countries and cultures. It can raise your mood, calm you down or give inspiration. But have you ever wondered when your music taste was formed?

A recent New York Times analysis of Spotify found out that the music we listen to when we are teenagers sets our musical preferences for the rest of our lives. 

That might explain why there is a generation gap in musical taste between parents and their children. It is difficult for parents to change their own musical tastes which were set years ago. Their children’s preferences, on the other hand, is still forming.
