The phenomenon is actually quite mundane. The footage, which reportedly comes from a forest in Sacre-Coeur, Quebec, is just showing us what happens when strong winds meet soil that’s been loosened by a storm.
“During a rain and windstorm event the ground becomes saturated, 'loosening' the soil's cohesion with the roots as the wind is blowing on a tree's crown," certified arborist Mark Vanderwouw told The Weather Network.
"The wind is trying to 'push' the trees over, and as the force is transferred to the roots, the ground begins to 'heave'. If the winds were strong enough and lasted long enough more roots would start to break and eventually some of the trees would topple.”
As defined by biologist Lincoln Brower, a "blue jay emetic unit" is the amount of cardiac glycosides (a type of poison found in plants such as milkweeds) that will make one blue jay vomit. Brower determined the exact amount by putting cardiac glycosides into gelatin capsules which he force-fed to blue jays.
The point of this was that various butterflies ate milkweeds and then became poisonous to the blue jays which, in turn, ate them. Knowing the exact amount of poison needed to make a blue jay vomit allowed Brower to rank each butterfly by its number of blue jay emetic units:
The experiments showed that a monarch that has eaten Asclepias humistrata contains enough poison to make approximately eight blue jays vomit; a butterfly reared on Calotropis procera contains 4.8 blue jay emetic units; one that has eaten A. Curassavica, 3.8 units, and one that has eaten Gomphocarpus, .8 unit. In other words, there is a palatibility spectrum, and the most unpalatable butterfly is at least 10 times as emetic as the most palatable one.
In 1980, Canfield's natural seltzer launched a campaign to promote its product as being great for watering house plants. It printed on its labels: "We recommend our natural seltzer for house plants."
Could there have been any truth to this claim? Is seltzer water actually good for plants? Well, the only vaguely scientific study I can find addressing this claim (after, admittedly, only a brief search) was a student project conducted at the University of Colorado Boulder in 2002. The student researchers concluded, "Plants given carbonated water not only grew faster but also developed a healthier shade of green in comparison to plants given tap water."
So, maybe Canfield's was onto something. However, if you're thinking of treating your plants to some seltzer water, I imagine you'd want to use water at room temperature, not refrigerated. Cold water might shock their systems.
In 1994, Jeff Goldstein, who described himself as a “semi-active pagan-Jewish minister,” got into trouble with the city of Madison, Wisconsin because he refused to mow his lawn. He claimed that to do so would violate his religious beliefs since he worshipped plants. He said he actually prayed to his lawn, and that to mow it would be a “holocaust against the green creatures.”
Goldstein explained that he had formed his beliefs after reading The Secret Life of Plants by Peter Tomkins and Christopher Bird. I’ve read that book. If you like strange science, it’s a good read, full of plant-science weirdness. Though I didn't come away from it believing plants are sacred.
The court didn't buy Goldstein's argument, but I don't know if he ever ended up mowing the lawn.
