I didn’t watch the whole video, but just economically your quote makes a whole lot of sense. Saving money and reducing our ecologicial footprint have a lot in common.
- Not having a car, instead riding a bicycle or taking the bus: less greenhouse gases, but also much cheaper.
- Cook your own food instead of buying over-packaged, ultra-processed food. I make my own bread which costs 0.75$/loaf vs. 3$ at the grocery store, for the same weight.
- Buying stuff that lasts not only reduces waste but also costs less in the long run.
- Leisure: reading a book is cheaper than going out.
on the “big picture” side of things, this pairs with the meme “what if we create a better world for nothing” – the points on the board behind the presenter are just “side effects” of cleaning things up
