Would you eat a dinosaur? Ride one? Keep it as a pet? Raise them on a farm?

The Earth is greener today thanks to CO2 fertilization from burning fossil fuels. We’re pretty much getting closer and closer to recreating the same atmospheric conditions. the dinosaurs lived in millions of years ago when carbon dioxide levels were above 2000ppm, it was also warmer. There would probably have to be a huge reduction in human population and massive reclaiming of arable land for thicker vegetation, so that oxygen levels could rise to above 30%, but then huge dinosaurs could then be supported with more oxygen available for metabolism.

Wouldn't help- you're forgetting a key component: gravity. 150 tons of debris isn't much, compared to the total weight of the Earth, but that's every single day, over literal scores of millions of years. You probably couldn't sustain something like a brontosaurus these days. Smaller ones would likely be okay, but you'd need to seriously revamp the food chain to keep them fed, unless you were dealing with smaller numbers; breed them for collectors and the like, and you MIGHT be okay.

Gravity? You mean weight? Yes, herbivores can consume large amounts of vegetation. Mass-wise, tending a brontosaurus is the equivalent of having 30 cows in a pasture.

No, no- THEIR weight. Gravity gets stronger when the weight of the planet increases, and it's notably higher than it was even sixty million years ago. The larger ones wouldn't be able to support themselves now.

You mean from this?:

That’s a cool fact about the space dust. According to this, the Earth is actually getting lighter on the net from larger amount of atmospheric stripping (Hydrogen and Helium). However, it’s not really appreciable. Earth is heavy.

That... that doesn't make any sense. Depleting 114,000 tons of atmospheric hydrogen every year would've run us out millions of years ago.

Good observation, around 2.5 million years at 0.000055% Hydrogen from a total of 5.15E15 tonnes of atmosphere.

Wikipedia also says we lose about 3kg/s of Hydrogen which is pretty close to what that other article said.

However, apparently the Earth is about 0.15% Hydrogen, much of it in the ocean. So my guess is hydrogen is being replenished in the Earth’s atmosphere from the breakdown of materials like water.
