The causes of the world's problems lie in bad relationships with others (and oneself) (e.g. greed, indifference, hatred) The lack of appreciation for nature and other people, which stems from "otherness".

The root causes of the world's problems:

1) people's bad relationships with other people -> social problems, such as racism, poverty, wars

2) people's bad relationships with nature -> ecological problems, such as climate change, water shortages, deforestation

So every problem's rootcause is psychological
