A/N: this is something I just wanted to point out the guy in the video says about the escaped dinosaurs and how it doesn't matter.

  "the movie really seems to be trying to make us believe that this actually is going to have an impact on the world. As in, there are now dinosaurs in the world and that's just a permanent thing. And no. They would just get fucken taken out." 

You seem to be confused. 

1. The Lost World: Jurassic Park, One extremely pissed off Tyrannosaurus and the results of it's attacks were enough to cause some massive damage and casualties in San Diego. How much damage do you think even more of these animals would do if they were in any big populated areas? 

(He also brings up some sort of animal control earlier about it. But I forgot to type it).

2. The hell kind of buffed up animal control are you even talking about that knows about dinosaurs? Especially one that would need high caliber weapons for taking down something like a Rex? 

3. Most of the herbivores are likely to only get captured if they walk into a public area. But considering they've got enough space in a vastly large forest area, why would they? as for carnivores, ones like baryonix can stay in the sewers, rivers and lakes, while something like the carnotaurus would stay in the forest to hunt and wildlife or lone person there. Even if they send someone into the forest to go after them, they're is no way that all of them that go in there will come out alive. 

4. we don't even know if the authorities have any info on the dinosaurs inside the Lockwood manner. Not to mention they probably don't even know what types they are or know how many there are. 

5. Pteranodons (which are not dinosaurs) can fly and set up nests anywhere they want. They will likely be wide spread. 

6. Small dinosaurs like compsognathus will be difficult because they can breed rapidly and are small enough to avoid being detected in even the most busiest of cities. 

7. The Mosasaurus (also not a dinosaur) anything short of a torpedo won't stop it. And it's going to be really difficult to find since it can swim around nearly anywhere in the ocean. 

8. You seem to have forgotten that there was a multitude of auctioned off dinosaurs as well as the taken embryos. Not to mention that the canon dinosaur protection group website even stated in an article that sometime after the first Jurassic World, there was a claim by rouge groups that they quote on quote: had access to cloning technology. So that already tells that there's gong to be more than just these 11 species. Yes, they'll try to be held by the companies or corporations that cloned them. But, knowing them, they won't be able to keep that power for long before they escape into the rest of the mainland as well. 

To put it simply, the situation is a lot more bigger than you think it is.  

And a tiny litte side note: there was only 1 rex on nublar. The movies and official sources themselves outright state this.
