This year is good. Less people die from bad groups. This is good for everyone. But, two places are not happy.
Nigeria and the DRC have more bad things. Bad groups make people sad. More people die in these places.
Nigeria has big problems. Many people died there. Old fights are still happening. Bad people make more trouble.
The DRC also has danger. More people die there. A bad group is causing pain. These problems are in Africa.
The world is safer now. But one man is worried. He says it is hard to stop bad groups. Some young people join bad groups.
