I find this all very interesting and it gives me much cause for thought.
As I see it, there is Suffering around us. It can be human beings, animals, and even trees, plants etc. One can be sensitive to it all and feel sad and deeply affected (or not).

The second part of the equation is 'What Can Be Done?'
This divides into two parts :- What can Those In Authority Do?'
and 'What Can I Personally Do?'

Some people are totally immune to Suffering, and either don't notice it or completely ignore it.
Some feel that 'Nothing Should Be Done' ('they brought it on themselves', 'they don't deserve help' etc.)
Those in Authority may say 'There's not enough money available', 'It's not our problem' etc.
An individual may think 'My family need my resources, no-one else'.
Or 'They look dodgy, I don't want to get involved'.

OR:-
Governments can be determined to address things, set aside far more financial coverage and call in experts, people experienced in the field etc. and really do as much as possible to make things better.

And an individual can, as some on here have already said, do small things in a spirit of kindness and understanding, show compassion and fellow-feeling, determine not to think badly of those who have fallen by the wayside (never mind how smelly, scruffy, drunk, weird, dodgy), and donate whatever they can afford, no matter how small, to Charitable Organisations who know how to act.
It all boils down to mindset, and my two great mentors, Wisdom and Kindness.
