What If T-Rex Were Still Alive?

tyrannosaurus rex king of the tyrant lizards it's 6 meters tall 12 meters long and it weighs upward of seven tons you can hide from it you might even be able to outrun it but do you really want to do this every day what would it be like to live with t-rex would we keep them in zoos would we eat them in restaurants would we wear them on our backs or would we live in constant fear of being chomped clawed or trampled this is what if and here's what would happen if t-rex were still alive roughly 66 million years ago a massive asteroid thought to be about 15 kilometers wide hit the earth with an impact equal to several million nuclear bombs detonating at once this triggered the sudden mass extinction of approximately 75 of all plant and animal species on the planet among them was the most powerful terrestrial predator to have ever lived the tyrannosaurus rex as one of the most popular prehistoric animals being able to see a t-rex in the flesh is a pretty common fantasy but what if we got what we wished for and t-rex were still alive today would humanity be able to survive alongside them were t-rex as vicious and as ruthless as they appear to be in movies and tv or would these massive dinosaurs be more worried about us than we'd be of them [Music] if t-rex were alive today chances are they'd be an endangered species their terrifying reputation would be no match for the habitat loss pollution and food shortages caused by humans because of this t-rex populations would be a lot smaller and it's even possible that they would have evolved to be a smaller size we'd probably have to keep them in sanctuaries similar to a wildlife safari since letting them roam freely would be bad for both t-rex and humans in the wild a t-rex would have to look out for hunters or poachers who'd want the thrill and the bragging rights of taking down a seven-ton beast but even if you were smart enough to keep your distance a hungry t-rex looking for food might find itself stumbling onto a farm or breaking into a city zoo and if you can't imagine a rampaging t-rex storming around your city just imagine an upright bus with two legs and sharp teeth that have a maximum fight force of about 5 800 kilograms but it's not like t-rex would always be out hunting humans scientific evidence suggests that t-rex might have been more like scavengers than predators unlike most predators that tend to have super sharp vision a t-rex's eyes were small and weak this dinosaur also had unusually small arms compared to the rest of their body which wouldn't have been very effective for fighting prey however t-rex did have unusually large olfactory lobes as part of their brains which scientists think would have been helpful for smelling rotting carcasses from far away but that same powerful sense of smell might also draw t-rex to country ranches or urban meat factories which would almost certainly end in disaster a t-rex could eat up to 230 kilograms of meat in just one bite so your farm animals wouldn't last very long and if you wanted to defend them or simply prevent your house from being crushed you wouldn't be able to take on a t-rex without a gun and if you didn't have one you'd have to run for your life t-rex weren't super fast runners with some scientists believing their top speed was around 16 kilometers an hour so if you ran and hid in a dense forest where it would be hard for them to maneuver you might be safe you could also try to trip the t-rex that's chasing you since they're top heavy dinosaurs that had a hard time getting up if they fell of course we wouldn't have to worry about endangered livestock and outsmarting t-rex if we kept them safely confined to wildlife preserves we could create large habitats for them and grow food to feed them so that their appetites wouldn't get them or us into trouble the sanctuaries probably wouldn't look like anything from jurassic park since well we've seen how well that worked but maybe with enough space food and under proper management humans could coexist with t-rex but the t-rex is just one type of dinosaur could we live with others too what do you think the world would be like if none of the dinosaurs ever went extinct well that's a story for another what if you
