          No, it can't. The earth only has a finite amount of oxygen in it, and either all of it is locked up in carbon dixoide or that carbon is buried in the crust and the oxygen can be free to be O2. Combustion engines are literally killing the entire planet.

            >The atmosphere of the Earth 80 million years ago was discovered to have 50% more oxygen than modern air. Brenner and Landis found that for all gas samples taken from amber 80 million years old the oxygen content ranged between 25% to 35% and averaged about 30% oxygen. Cretaceous air was supercharged with oxygen.

            There is a shit ton of oxygen available at any time in earths history in the water of the oceans and other mineral deposits. And CO2 is not the only chemistry for greenhouse gasses. If the biosphere generates an excess of methane for instance, you liberate more oxygen and use that leftover hydrogen to make a more potent green house gas. Why are you like this?

                The amount of all the elements, oxygen, carbon, nitrogen etc. is essentially the same since the formation of the earth. But they can be sequestered or free in a gaseous form in different ratios for a number of different reasons. Such as being chemically bound in a solid or liquid or literally just buried underground. The composition and thickness of the atmosphere can vary wildly over the course of millions of years due to random geologic or living processes. It's not like the earth knows there has to be an exact amount of oxygen in the atmosphere and it can only swap o2 for co2 or something. Anthropogenic climate change is not caused by digging up co2, its caused by digging up just carbon. If for example humans decided to refine all the buried iron oxide into steel we would add a bunch of oxygen to the atmosphere but the climate wouldn't cool off. We would still have the same amount of co2 up there. So we would have both a hotter and more oxygen rich atmosphere.

                Which is burned to produce... CO2. Which removes oxygen from the atmosphere and ties it up with CO2, which heats the Earth at the same time we are literally running out of air we need to breath. There is no efficient way to untangle carbon from oxygen in CO2 without massive amounts of energy that would just put more CO2 back in the atmosphere. You cannot run from this, it is basic chemistry.

                You do realize that Co2 in the atmosphere had plummeted to near critical levels over the 500 or so million years of carbon based lifeforms depositing carbon into the earth right?
                300 million year of shellfish extracting carbon from the cycle and depositing it into their shells, which then sink to the bottom of the sea had almost depleted carbon levels to the point where plant life could no longer be supported.
                For every kg of fossil fuels there are ten tonnes of carbon rich limestone in from sea life alone, deposited deep beneath the earth. Blasting that Co2 back into the atmosphere is good for biodiversity on this planet... but because some climateisraelites wanting return on their renewable tech since we kept on finding new fossil fuels, morons like you are propagandized into believing that the climate ca. 1870 is the not only the best climate, but the only climate allowed.

                If it is such nonsense, you should be able to easily refute any of the points being made.
                Has carbon not been lost from the system due to carbon based sea life over hundreds of millions of years?
                Is it false that plants do better if the atmosphere has carbon levels 2-3 times higher than today?
                Why is it true and good to claim that an arbitary point in recent history is the correct and "normal" climate levels?

                Go on then, should be easy for you to dismiss my concerns off the top of your heads since it is such nonsense.

                Not really. Humans really do best in grasslands, savanna, and tundra. "Tropical" would imply something more heavily forested, which Humans do not dislike but will actively destroy in order to create its preferred biome.

                And "tropical" would also imply we thrive in only warm climates, when we ALSO thrive in cold ones. The one uniting factor between savanna and tundra? GRASSLAND.

    I'm guessing they use that bulk to push rivals around. While allosaurids have strong forelimbs that they can use to "grapple" like komodos, T. rex just opted for weight.

    I think they got fat as they get older, and as sub-adults they're more agile.

      I'm an American Dinosaur, so I’d just absorb it with my fat and muscle density caused by carrying all of my fat. Slowly, I would waddle towards you, my mutt genes desensitizing me to pain as you furiously flail your underfed claws into a gut rendered impervious as Ankylosaurus hide by a steady diet of Papa Jobaria’s and Argentinosaurus. With a roar to my Velociraptor, Spinosaur, and Nigersaurus ancestors I would turn my swollen neck skyward, and spread my hand nubs wide, the wall hitting your back as you shriek in sudden fear and realization before I grab you in the patented ‘Lagarto De Las Americanos Hug’ and stuff you headfirst into my drooling maw, biting down on your thin neck and shaking my head like a small mammal to end your suffering-filled existence. Then I would bread you, fry you, and consume you like a family sized bucket of tasty Kentucky Fried Cearadactylus.

    Because T. rex was literally a spin off of a primitive bird and they get like that sometimes

    Or more accurately, birds a small theropod dinosaur, and the term "bird" being its own thing is an artifact of a primitive culture without an understanding of phylogenetics (like calling dolphins fish).
