I'm not saying it happened, I'm saying we don't know if it happened!
But THAT ABSOLUTELY HAPPENS as long as there is evidence that humans have seriously altered ecosystems everywhere ... and that we ourselves are part of ecosystems and LIVE in those ecosystems that we have dangerously created / modified (cities) and that these viruses have moved and are swarming in the most seriously polluted areas of said disturbed ecosystems! Whether the trigger took place in an ice floe, a mine in China, during crushing in a lab or whatever, is not the most decisive. The decisive point is that ecosystems conceal conditions, a terrain, particularly favorable to the emergence and the propagation of viruses which have been exacerbated ... The other decisive point is that by modifying our relationship to ecosystems , we have partially lost our ability to respond to them, and have in certain areas of urban concentration (and all over the planet), deliberately (or not) weaken our species.
For SARS-cov-2 classified as a trigger vector for severe lung disease, this is particularly the case.
The scientific studies which prove it come out one after the other, and moreover, the covid is added to a pre-existing state of affairs, which confirms it
