some context:
I work for the parks & gardens service of a local authority, in a mostly urban environment. My specific work area is a public park, that is ~30 acres in size.
What I encounter on a daily basis, is:
Young children unable/unwilling to play in the swing park, because of the broken vodka bottles, the hypo needles, the used condoms, the damaged play equipment.
Older children unable/unwilling to play on the football pitches, because of the glass shards.
Pensioners unwilling to enter the park after late afternoon, because the council stops working at ~4pm, and they don't feel comfortable.
People unwilling to walk their dog in the park, because of vet bills for cut paws, because of glass shards.
There were hundreds of shrubs planted, that were all torn out and thrown around.
There were dozens of trees planted, that were all snapped in half.
There were several flower beds planted, that were trampled.
There were several benches installed, that were broken and lit on fire.
These problems, are all caused by a tiny, tiny number of people that ruin things for thousands more.
And the problem causers, are the same people that do not want a job, and are content to live off benefits.
It's not all grim, there was a charity football tournament last weekend, that had a good turnout of people. However, many of those people are uncomfortable about visiting the park outside of there being an event like that on. Because of the actions of a handful.
People stop and talk to me, and say things like "I don't know why the council bothers, they'll just get vandalised" and "it's heartbreaking seeing stuff like this" and "scum, the lot of them" and so on and so forth.
The positive mental health benefits of green open spaces are vast, but because of the actions of people that refuse to work, refuse to contribute to society, something that should be making thousands of people happy, instead makes them depressed. And that poisons the whole community, makes less people interested in life.
Also, tax dodgers are also poisonous to society.
