Why are people so destructive?

The waiting room gallery looks after a part of Longport Station and is trying to restore part of it. They have also planted shrubs and plants to improve the site. But they caught someone pulling up plants. Stealing them! This shrub was rescued and put in the sink to stop it drying out. It’s going to be replanted. But I can’t get over how mean people are. We also saw some broken windows. Can’t people leave things alone?!
