This is a great list thus far! To add to the tiny house: In Canada we have a Zero-Carbon Building Standard for new homes and buildings. (https://www.cagbc.org/zerocarbon). Also-I might add community vegetable garden coops where the whole community shares in the vegetable harvest each season (though not sure how drastic that is).

Human behaviors that threaten environmental sustainability include the rapidly growing human population and the depletion of natural resources, such as water, forests, fish and fossil fuels. If resources are used too rapidly by man, nature will not be able to keep up with the demand. https://study.com/academy/lesson/human-behaviors-that-threaten-environmental-sustainability.html

Ryan Churchill Thank you!

I think I will add, some kind of gardening. I also got the suggestion to add self-sufficiency. That would include gardening. Though, I was also suggested to add some more community-related alternatives.

So thank you, good suggestions.

Chinaza Godswill Awuchi exactly. So, I am looking for solutions that people implement. Though I am not looking at the already easily available solutions. I am looking at more "drastic" changes. It would be very interesting to read your ideas about this? I am aware that people in Uganda have other options and possibilities than someone, say in, Austria. Are people engaging in alternative lifestyle voluntarily? Are there people who resist the western growth narrative?

I am not sure if this is still an active area of research, but you might investigate downshifting/downshifters, which I believe gained traction in the 1990s. Conceptually, downshifting is similar to minimalism, though I believe downshifting is distinguished by voluntarily working or earning less (e.g., by reduced work hours). The idea is to break, as Juliet School put it, the work-and-spend cycle. Some people, I'm sure, adopted this lifestyle for the sake of the environment, though I could imagine that many more just wanted simpler, less stressful lives.

Your original list seems quite good. I would be interested to see what comes of your project.

Joseph Kantenbacher Thank you! I will have a look at this concept. The working hour reduction is becoming a topic again, esp in the degrowth, sufficiency literature.

I will keep you updated on the project outcome!
