I also echo the sentiment that we should both create a culture of questioning excesses, enjoying a simplified lifestyle of essentials: good health (address pollution, agriculture filled with toxic compounds, etc.), peace, arts and culture, instead of often self-destructive excesses; and that we should look at effective interventions: feeling good about it is not enough, we need actual effective change!
Some of the most effective changes you can do individually[1] is (1) reducing meat consumption significantly;[2] (2) Less air travel (3) Use alternative forms of transportation (bike, walk, public transit, live near work?).
(Of course, if you have a huge house with tons of appliances... I'm sure that's highly significant!)
I'm doing all those things personally. And as honest as I can: I think my health and wellbeing genuinely improved (I've lost weight due to better mostly-plant diet, am much more fit due to walking and public transit; I guess there's a psychological factor from knowing I'm helping too!). Public transit is the most inconvenient sometimes (other times it's far more convenient), but then I'm not absolute and take a ride faring app every now and then. Living this way isn't only possible, it's genuinely good.
Discovering places nearby to travel and connecting with local history and culture is something I also think we could do a lot more.
And by all means, be politically active on this issue! (I can't change things like energy matrix with individual habits, but I can vote well)
I'm with you dude :) Hack the planet!
