Would we actually let them live and give them enough space to thrive? Or would modern humans wipe them out via poaching or leaving them too little habitat to survive in?
Let’s say brontosaurus’s, t-rex, and a bunch of other dino’s suddenly showed up in an Iowa cornfield conveniently close to one of their giant pig farms and the carnivores start raiding the pens.
Smaller animals are far more efficient for food than larger ones.
For example, it takes 6 pounds of feed to produce 1 pound of meat for a cow, but it only takes 2 pounds of feed to produce 1 pound of chicken. I believe the term is FCR, or food conversion ratio.
Which is why it would take an enormous amount of land to sustain some today. I’m not sure the majority of Americans are willing to “share” even with something as magnificent and amazing as dinosaurs.
Could humanity surprise us and truly become a conservationist society if we suddenly had these magnificent creatures back? Or are we just the plague that continually destroys life on Earth no matter how amazing it is.
If they had so much trouble dissipating heat being that large, it must have been a nightmare considering the Earth was so much warmer back then. I can see why the Stegosaurus and Spinosaurus developed those back plates.
In this hypothetical are we away of past dinosaurs and now by some miracle they are back? If so they would be Jurassic Parked. We would certainly want to keep them alive, but in controlled numbers in a controlled environment.
Alternatively if the hypothetical is that they survived their extinction event and humans and dinosaurs walked on earth at the same time then the answer would probably be that we lost that battle before it even started. I don’t see pre-stone age man standing up against dinosaurs.
If they got dumped here today there would be a massive effort to keep them from extinction if only because they have such good PR, in my opinion. Land would be apportioned for them to roam around.
