This is the best video I have found on COVID-19 so far:

A lot of the things mentioned there makes a lot of sense. The pollution we cause could be linked to all the pandemics we are facing from flu to COVID-19 to autism. Even the entire "Germ Theory" which has enabled medicual industrial complex in many ways could be at the risk of loosing its grip on modern medicine.

In 19th century France, while Pasteur was advocating the notion of germs as the cause of disease, another French scientist named Antoine Bechamp advocated a conflicting theory known as the “cellular theory” of disease.

Bechamp’s cellular theory is almost completely opposite to that of Pasteur’s. Bechamp noted that these germs that Pasteur was so terrified of were opportunistic in nature. They were everywhere and even existed inside of us in a symbiotic relationship. Bechamp noticed in his research that it was only when the tissue of the host became damaged or compromised that these germs began to manifest as a prevailing symptom (not cause) of disease.

To prevent illness, Bechamp advocated not the killing of germs but the cultivation of health through diet, hygiene, and healthy lifestyle practices such as fresh air and exercise. The idea is that if the person has a strong immune system and good tissue quality (or “terrain” as Bechamp called it), the germs will not manifest in the person, and they will have good health. It is only when their health starts to decline (due to personal neglect and poor lifestyle choices) that they become victim to infections.

Traditional Chinese medicine, which dates back more than 2,500 years[3], treats the whole body instead of the symptoms of illness.
Even Hippocrates, considered “the father of medicine” observed 2400 years ago to “leave your drugs in the chemist’s pots if you can cure your patient with food.”
Thousands of years later, Thomas Jefferson advised, “The doctor of the future will give no medicine but will interest his patients in the care of the human frame, in diet and in the cause and prevention of disease.” And yet, we can’t regain the deep truth that the right, whole, nutritious food can nourish an internal state of health that puts out a “Do Not Disturb” sign for most chronic diseases.
