Read the paragraph below.

Slavery still exists. The United Nations says about 50 million people are enslaved today. They are in forced labour or marriages. The U.N. said one in 150 people in the world is enslaved. This number increased by 20 per cent in the past few years. lt is growing because of coronavirus, climate change, and the cost of living crisis. These have made many people poor. They can only survive by working in terrible conditions having an unwanted marriage.
