I'm glad you brought up these points. If you want to understand why Dharma (aka 'Hinduism', 'Buddhism', 'Sikhism' and 'Jainism') are NOT akin to religion, you might find the following article insightful:

This ecology article was a way for me to explain my own intellectual journey, not sound exclusivist. If there are any ideologies that should be called exclusivist, it's Abrahamic religions - Islam and Christianity fundamentally and scripturally do not recognize indigenous knowledge traditions as valid paths to the divine, which has been the root of so much bloodshed and violence throughout history. No matter how much good is found in them, I do not personally think that humanity will be able to move forward in harmony without reforming these intolerant aspects, which is why I do not go out of my way to highlight their good parts, especially when the context does not call for it.

That being said, you've made some very good points about how we technically have all we need to solve the Earth's crises. Why, then, are we not actually able to do so? When I answered this question in all its depth, over a period of years, I came to realize that certain civilizational foundations are more practical than others. If you have the patience and open-mindedness to understand those foundations, you might see how forcing everything into a Western framework is not the best idea.
