What makes them vulnerable? What are they vulnerable to? Are there not indigenous peoples that live in harmony with nature? Are they prosperous?
This is usually called poverty.
They couldn't care less for those forgotten children.
Had that beautiful field or wooded area been given a "nature cost" to destroy, maybe the developers would have made other choices.
They could use cars, ambulances, hospitals and etc.
Nature is brutal, always has been, no one lives on harmony with it.
Look at the indigenous peoples death rate, child mortality.
Probably there are some somewhere. But most rely on completely unsustainable practices.
> Are they prosperous?
You've received some answers, but keep in mind that "poor" is a word we usually apply to people in much wealthier situations.
In what way are the practices unsustainable? Could you give me an example?
It would really be easier if you explained why you think indigenous (to where?) people live in harmony with the nature.
