None of the clouds in this post is natural. Just like food-like food, these are cloud-like clouds. They are all man-made, processed. Processed clouds result from plumes emitted by jet aircraft or some other method such as ship-launched missiles from the ocean.
It is now a known fact that most of these processed clouds contain an aluminum-oxide emulsion to reflect sunshine. Why? Ostensibly to reduce global warming. Aluminum is used to reflect heat, much like aluminum foil is used in an oven to protect a turkey from burning.
The unintended effects mean that the aluminum oxide clouds eventually drop to ground level, accumulating in the soil, water, and in our bodies. This is thought to reduce the quality of all life forms — plants, trees, insects, animals, humans.
