The question is do people want this alternative? You have to look at big picture. Most people put convenience, comfort, and temporary pleasures far ahead of own health. And you can't change that. That's a human nature.
Saying it's "human nature" is like saying "god made it". They both keep you from looking further for real answers.
Why do they put all those things ahead of own health? "Human nature" is no answer. And yes, you can change that. But first you have to figure out the reasons and causes why people are as they are, why they value what they do. And there are many reasons, many answers.
In case of headache or stomachache most would prefer a quick pill. Very few would take longer natural approach. 99% of the population is satisfied with symptom treating. Because it is convenient and give immediate results.
Why is it convenient and as if "gives immediate results"? Why can't they see the bigger picture? Why can't they see things so obvious? Why are they so blind?
"Human nature"? No.
That's the reason why fast food is thriving even though every media outlet have been blasting it for the last 15 years or so. That's the reason why people smoke, drink, and use drugs.
"Because it is convenient and give immediate results." Or perhaps there's deeper reasons? Not convenience and in this case definitely not immediate results. If they are known to be so bad even by doctors, and there are many studies proving it, then why are they still being
produced? The general population is not responsible for producing all that crap, they just do their job in exchange for a crappy salary that can barely support them.
Why do they make such crap if they know it's not good? Why do they work for such low salary? Why are they paid so little? Why don't they like getting paid so little? Why aren't they doing anything about it? Why do they just follow the "rules/laws"? Why are the laws allowing such crappy conditions? Who made/make those laws? Why would they make such laws? Etc. Answers for all of them and it's not "human nature".
That's the reason why Chinese and Indians are massively copying western style of living. It gives them what they want - convenience and temporary but immediate comfort and pleasure. All people are the same.
Not so, not "human nature". It's hard to prevail in a world that grows bigger while you remain the same. The bigger it gets the more it will influence, doesn't matter what qualities the bigger side has. The smaller either goes along or fades away, either way will lose, unless the values differed from present ones and they'd be given a chance to grow as they should with their defining qualities.
Indians were destroyed by greedy europeans long ago, putting more than just a halt to their progress. They have no real land of their own, not anymore, they aren't really free as a people. They have no other option. A defeated people, sad (hopefully not true, but hey, kinda can relate...).
China's change began with the communism thing, or before that even. Or rather, China hit a dead end on its own, so going the western path was an easy way of moving at least in some direction. Funny how it's still regarded as a communist country while in truth it is not communist at all, pure dictatorial capitalism there. As well, they do produce so much that is shipped outside, made by cheap labor, as good as slaves really.
That people in general are all the same is no indication of why things are as they are. You still have to ask why? You get an answer, and you ask the same question from the answer. Then again, and again, until you get to the root cause or causes. And then should become obvious that things can be changed, that saying it's "human nature" is avoiding the solution.
The question is do people want this alternative? You have to look at big picture. Again, you are not seeing far enough.
And neither are you.
