So, reading about the earthquake in New Zealand gave me an inkling of hope because the residents seemed to be pulling together, sharing food and shelter, and basically being decent.
Then I came across this (and it is about people that supposedly care about each other - we can expect starving, desperate, migrating climate refugees to resort to much worse):
Domestic violence rages in NZ quake aftermath
There was a spike in suicides and stress-related conditions after the first quake, and David Meates, the region's health director, said Tuesday's disaster "has certainly got most people very, very fragile, very anxious".
"In these sorts of situations there are enormous pressures and strains on families, relationships, people's livelihoods are now at stake," Meates told AFP.
"Sometimes the way that it's expressed, people are a lot (closer to) their breaking point and sometimes some of the reactions can be quite out of character. Certainly domestic violence is something that becomes more obvious."
Already a major problem in New Zealand, with tens of thousands of incidents reported each year, one local study showed the incidence of domestic abuse could triple during natural disasters.
Massey University researcher Ros Houghton has found events such as floods and snowstorms significantly increased the intensity and frequency of abuse in rocky relationships.
"People lose a sense of stability and security and there's a kind of anger that comes and you don't know where to put it, you don't know where to direct it, and it's often that it gets directed inside and against those you love," said Peter Beck, dean of Christchurch's Anglican Cathedral.
"Already we have people who've been made redundant, so there's anxiety not only about your homes and your loved ones. Some people have already been getting this double-whammy of maybe losing their job."
