When people see these kinds of things, they believe that it has to be done right now and it has to be done 100% and that should be the end of it. What people do not realize is that we could provide a lot more profit to people who recycle and repair and refurbish etc etc, and as people we could see stuff that are not brand new as still okay, then we will be doing fine.
We do not have to change it all, we could simply just do something like a bit more laws that support it, just paying more to people who recycle, paying more to people who pick up trash and put them in right places, all in all just promote this kind of behavior while also allowing brand new stuff as well, keep the world as it is on this part. Basically what I am trying to say is that, this could be an "option" and not forced and it would still be a lot better, it's proven that it would help the world for sure.
In regards to paying people to pick up trash, I think you could do that in a way that does not encourage them to throw away trash in order to recieve more payments. I won't be surprised if those you pay to pick trash, secretly trash a clean place in order to get more payments. Maybe they should be rewarded more (not necessarily with money) if they are able to maintain the cleanliness or prevent people from littering the streets at all.
If everywhere remains clean and there is no job for them, they could litter the place themselves to continue to recieve rewards.
I'm not sure who deliberately and massively trash a place that was paid for to be cleaned. Sometimes I suspect it's those you paid to clean it up because one of them always comes by to ask that he gets the place cleaned up again. Or it could just be neighbors who are too stingy to pay for trash pickers, or just sadists
They should basically be paid sufficiently if they deserve to paid or if everything is done right.
