Vitamin K2 is crucial to move calcium from the blood and soft tissues into the bones - where it can make bones strong.
K2 is abundant in animal foods, but not in plant foods.
Also, a lot of the bone matrix is made of proteins - and proteins are more complete when they come from animal foods.

A shame you dont click my link to Scientific American.

Well, as I’ve already said to the other person who said the same thing, it was a typo on my part exchanging “flowering plants” for “asterids”.
However, you should actually read the article you cited, because neither it nor the academic article it references present any evidence whatsoever of plants 140mya with morphology similar to what we call flowers. It is entirely a theoretical exercise.

>that structurally complex, modern-type rainforests may have been around as early as 80 million years ago.
Flowering plants arose at least as far back as 140 MA, the article's point is that such woody vines were around prior to the dinosaur's extinction.

Happened due to earthquakes but glaciers came down and destroyed entire towns.

It would be a more substantial opportunity if those solar panels were on top of moderately priced housing where parking lots used to be.

Has already happened in Latin America. Took out a whole town in the deluge.

There is a reason why we do not see huge vegan populations on earth.
Were it more evolutionary for than a mixed consumption, we'd see large groups.
There are not. The closest we get are large religion is vegetarian groups.
Going vegan is clearly evolutionarily unfit.

How vulnerable are solar panels to vibration? Like if you installed them on a canopy over a freeway would they last or would the vibrations from the road damage them?

Not most voters. Just most voters in fossil fueled states, many of them rural, who get unfair extra votes due to an antique Constitution that has become the fossil fuel industry's primary weapon against climate solutions.

...fast enough for what, exactly?
A 15-20% emissions reduction by 2030 puts us on the second-lowest IPCC pathway which is estimated to result in 1.8C of warming by 2100 (+0.6C above today), in line with Climate Action Tracker's estimate.
So we're certainly not on track for holding warming to 1.5C; however, we are on track for holding warming below 2C, which is a better outcome than I expected even just 5 years ago, and is far better than Climate Action Tracker's most optimistic projection from 5 years ago.
It's not perfect, but it's substantial progress, so I'll take that as a good starting point.

Not only that, but the coal plant will poison fish with mercury, making them inedible, for a thousand miles downwind.

Solar pro here. If you want to pay more, build solar carports. To pay less, put arrays on open ground or on rooftops.

It’s all pointing to the same thing.
Here’s a meta study as well.

That is correct. The second “flowering plants” was a typo on my part, and should have been asterids. That said, I could still certainly be outdated on my understanding of the advent of asterids. To my knowledge the oldest specimens are dated to the Coniacian.
