OK, so I plant trees. But it's not the only thing I do. I have been off grid for 25 years, except for this new house that we've just moved into, but we are working on it - as fast as we can!
Yes, I have seen the movie "The man who planted trees", but long before that, I had read the book. After all Jean Giono is a prolific French writer and he was part of the curriculum in our literature classes.
I have never had a dish washer, a microwave, a clothes dryer, an electric cooker, a freezer, a hair dryer, never used deodorant. I have not used shampoo, detergent, cleaning products for years. My washing machine is one of those: https://uktwintubs.co.uk/product/7-2kg/
It uses 365W for washing and 185W for spinning. I know the power consumption of every appliance in my house - which you need to if you are on solar power. By the way, I don't iron clothes either, but if I really, really need to then I use one of those cast iron "iron" that you heat on the stove top.
It was 1999 when I started in earnest to lower my carbon foot print, but I had been aware of my faulty living long before that. It was then that the TV went and I curbed my use of plastic. I stopped buying anything with palm oil in it which was not easy then because they used about 50 different names for it, so reading the labels was fairly confusing. By the way, I am sure you know that it is not only in food produce. It's almost as difficult to avoid palm oil as it is to avoid plastic: https://www.worldwildlife.org/pages/which-everyday-products-contain-palm-oil
Plane travelling went a long time ago, except for the one time when my eldest son had a stroke on the other side of the world. We have a big 4x4, but we use it only 3 or 4 times a month.
It goes without saying that I gave up on many things that came from far away, and it was not as hard as I thought it would be. We eat local or grow our own. I am trying to avoid supermarkets, I go to local shops if I need to. My entire house is furnished from second hand , inherited or gifted furniture and my wardrobe also is second hand. I can't remember the last time I bought a new item of clothing. Of course, I recycle, re-use, re- purpose, mend, repair and what not. There is very little waste in our house.
We often stop on the side of the road and pick up rubbish and where we lived before, we had a "clean the village day" twice a year. That included cleaning the stream and its banks, cutting dead branches, clearing gutters & gullies, weeding the communal gardens and many more. Always ending with a meal that every one contributed to.
A few years ago, we switched to an ethical bank that did not invest our money into arms deals and/or drug money laundering. We can choose witch green good cause we want to support and 1 cent of every card transaction is automatically given to those by the bank. Of course you can add to your donation if you wish to.
We have had WWOOFERs for many years and although we never preached, just the fact that those young people lived with us changed the course of their lives. With no expectations, we shared what we had and many a time, sometimes 6 months or even a year later, we'd receive a letter telling us that somehow, their stay with us really changed their lives, some even ended up going for a PDC. Only a lit candle can light another candle. Sometimes, you don't need to do anything, you just need to be.
We've just sold our well established Permaculture site and home to a young couple who wanted to have a foot on the ladder and carry on the project. We now have bought 8 hectares of very degraded land and we are starting all over again, hence: I plant trees, loads of trees and it fills my heart with joy - but then, I'm just a simple soul.
