How Has Climate Change Led to Violence?

Climate change has led to violence starting with water. In the video, in Yemen, there is a lack of water and the people there are struggling to survive. The water situation is so vile that the people in Yemen are literally fighting each other for water. They called this water situation a "fight for survival". They depend on plumbing pipes for water to drink, shower and wash/clean clothes, utensils, etc. They are lucky if it rains and in the video, I saw little kids playing in the rain and washing themselves. Water is a big necessity for survival. It is sad that they have minimum to no water supply to do their daily tasks and most importantly to live. Without water, how can someone live?
