Sometimes what you need are not "sustainable solutions", that's something you can afford when you are not struggling daily just to stay alive. Sometimes you just need something that solves the problem right now, damned by "sustainability".
Just like most people in poverty don't give a fuck about climate change, there are so many other problems on their mind about their daily life, that there is no space to focus on "bigger problems" or "sustainability", it's just about surviving and finding ways around whatever problem arises.
