Exactly, I totally agree with you.
The big problem today is called cancer, produced as you rightly say by heavy metals in the environment, pesticides, plastics, etc.
Curious that the cases of toxic substances that produce cancer are always covered up in the media, curious also that the WHO says that red meat is carcinogenic, when the incidence of cancer in vegetarians is much higher than in people who have a much more varied diet due among other things by the massive intake of pesticides.
