Guerilla gardening - turn public spaces into permaculture food havens peace by peace. Learn about grafting and graft fruit tree branches to other trees. This is both the solar and the punk.
Composting for your garden, container gardening if you only have access to a small patio garden, growing your own mushrooms and herbs indoors, beansprouts and things like that can be easy to grow in jars. This provides for you, improves your air quality if you do it right, and disempowers the capitalist system when it comes to food production, bit by bit. Turn your lawn into a vege patch that’s pesticide free, and invite all the creatures.
People underestimate the power of boycotting. Boycott any plastic you can. Boycott fast fashion. Boycott the motor industry - by all means learn to drive because you should never allow yourself to be deskilled in any way. Boycott planned obsolescence. People say “it’s not down to the individual, it’s down to the corporation”. I believe it can be both and boycotting is one of the places they meet. Voting, protesting, signing petitions are other ways individuals put pressure on big monsters.
Join groups. Cooperating with others in repair movements, allotment groups, town greening committees, and such is really important but if you’re an introvert then we need to really talk about all the ways you can coordinate with others without any social pressures - like information sharing through forums. You can share books, organise a clothes swap.
Help the elderly, impoverished, homeless, disabled. Many people literally can’t do anything to live more sustainably because they can’t afford to or haven’t got access to a lot of the things others do - such as information or entry to groups. If you add these people together they make the majority of society. Imagine making a difference to the majority of society!
Saving hedgehogs. They’re an endangered species and you can make space in your home but also most of the above actions help. If you think you can’t help in any direct way, think again! Find a local hogspital and donate things they need. Talk to them about local action.
Become a hunt saboteur. It’s dangerous but exciting.
Work towards living in a small house. Own less, do more, share more, travel more (if your home becomes mobile).
Use a zero waste shop, and if there isn’t one in your community the encourage people to want one and start yourself an eco business!
Spend more time in nature. You’ll notice things. You’ll start litterpicking.
Do a beach clean. I made a rule that I can’t take things from the beach unless it’s human made. I don’t do the pebbles and shells thing. I’ll fill two bags with plastic waste, and disguarded fishing gear, before I’m allowed to take home any pottery or beach glass and I kinda think everyone should do the same.
