Why not try volunteering? We are looking for volunteers to help promote Rise #bakery which is a #socent and is part of Providence Row - a fantastic chariety that supports homeless and vulnerable people. https://speedvolunteer.london.gov.uk/opportunities/2e9ee1cb-7dc7-4c57-953c-b636b0b8f847
"On one level, as so much twitter outrage has pointed out, these spikes symbolise the transformation of the homeless into a form of vermin. But their artistic resonance goes further than that. These spikes beautifully encapsulate the essential concerns of a society that has abandoned any pretence of social justice, fairness and equality, even to the point of refusing to ensure what ought to be the essential component of any civilised society - a home for all its citizens."

Here is an example by Stephen Shames. This photograph is documenting the dramatic life style of a homeless child. (Documentary photos of the life in the Bronx.)
