There are many challenges facing the world that are considered to be lesser or not as critical as some of the major challenges. Some examples of these challenges include:

1. Traffic Congestion: Traffic congestion is a common problem in many cities around the world, but it is not as critical as issues such as poverty, inequality, or climate change.

2. Social Media Addiction: Social media addiction is a growing concern, but it is not as critical as issues such as conflict, violence, or global health.

3. Obesity: Obesity is a major health problem in many parts of the world, but it is not as critical as issues such as poverty, inequality, or access to healthcare.

4. Animal Rights: While animal rights is an important issue for many people, it is not considered as critical as issues such as human rights, conflict, or climate change.

5. Corruption: Corruption is a serious issue in many countries, but it is not considered as critical as issues such as poverty, inequality, or access to education.

While these challenges may not be considered as critical as some of the major world challenges, they are still important issues that need to be addressed in order to create a more just and equitable world.
