I'm involved in a volunteer organisation in my city that takes excess food from supermarkets and bakeries and reuses it, if you signup to be someone to collect the food you can either keep it for yourself or redistribute it by taking it to a shared fridge for homeless people. There is often far too much for a single household so it usually taken to these fridges or shelters. I work directly as someone who collects the food and also on programming related tasks to keep the organisations website and apps running to coordinate pickups. There are 30,000 people involved in this initiative in cities all over Europe. While it may not "solve climate change" or "solve homelessnes" it has a direct impact on my local community, we can all only work in the frameworks we're given while rallying and voting for bigger systematic changes at the same time. The idea that one activity somehow cancels out or distracts from a bigger issue is bullshit, humans are capable of caring about and being involved in multiple causes.
