Mercury is part of the natural world but do you want to put too much or excessive amounts of mercury into your body? Do you want to eat raw meat? How do you eat meat? When you cook, do you want to change the molecular structure to the food you eat? Fire does not change the molecular structure like microwave ovens do. There are differences and microwaves are worse when compared with fire. Also, fire has always been more common even without humans as lightning produces forest fires. Some animals create fire from their mouths. Microwaves are not really natural and you know that. Why are you denying reality? Same thing with vaccines and geoengineering. It's like GMO.
