How has climate change led to violence?

In many places around the world, Climate change has lead to violence for a few reasons.  Being that climate change has increased water scarcity, it is harder for one to obtain water. Water supply is very limited and the places that do have it will sell it at a very high unaffordable price. This causes people to become violent and fight in order to survive. Economic factors and food security may trigger conflict in poor places. Poor places may have less of everything compared to the more stable parts.
