Maybe get rid of those billionaires and capitalists first before trying to survive on scraps. Nearly half of the food in grocery stores is thrown out while it's still good. Meanwhile people are now starving and there's even a return of scurvy due to malnutrition from food inflation and food insecurity.
Same with clothing. Companies like H&M shredding good clothes before throwing them out instead of giving it away or even selling them to places like Winners.
It's light were living in a global version of the Irish famine where everybody was starving and dirt poor, but they were making a fuck ton of food for the British.
And finally, what about how companies are doing programmed obsoletion of their products like electronics and appliances and design their products in a way that produces more e-waste? Or how everything is wrapped in plastic all the time? How is that the consumer's fault?
Change needs to start at the top. Cut the greedy fuckers out of the loop and you'll see how much waste we can reduce.
