Excellent read. Nature has so many answers for us, all the answers we need.
We have been told that we must attend schools and learn from experts, or we will fail as humans. This is false. If anything our reliance on others blinds us to our own innate understandings. Perhaps we too could make a knot suitable for a nest if we thought we could do that without a college degree in knot making. I'm stretching my metaphor here, but I think you get the picture.
We have been taught that we are born empty vessels that need filling, or we will remain empty. In fact, we are born powerful and intelligent beyond measure.
And yeah, reduce your exposure to toxins!!! Start right this minute! Begin by simply turning off your cell phone, or at least moving it a few feet away from you. Turn off your routers at night, or better yet, hardwire your computer and leave the router off. Go for walks in nature, without your phone. You'll be amazed by how much smarter you are when you do these few things.
Teachers try their best within formal education, mostly I remember outside of school activities taught, stars by my father in the garden with a telescope, staying at farms with relatives doing daily tasks allotted, history or cultural tours organized through schools during holidays.
Visits to planetarium, touring miniature mine shaft where gold was poured showing processes, events that don't leave ones memory when still under the age of 10.
This type of exposure one has to seek out, which I must say we were most fortunate. We grew up without much of what is here today, problematic in throw away world. As for phones and devices they remain a one room unless required for specific reason.
Nature will win at the end of the day, will we have sufficient knowledge to survive?
