Even in the city here I can harvest for free,figs,apples,plums,pears,damsons,blackberries,raspberries,Japanese Wineberries,walnuts,chestnuts,hazelnuts,medlars,Japanese quince,cherries,elderberries/flowers etc,no one else seems to bother,people have food growing at the bottom of their gardens and get they will let that rot and buy THE SAME fruit from the supermarket because they think if it's growing here it must somehow be inedible,,any work that anyone can do to reconnect people,whether through faith or through other community based work can only be a good thing
