Ha ha, no. In a million years, mankind would have paved the entire planet's surface, including the oceans. Our numbers would be in the hundred billions and most will live underground. The few elites would live on the uppermost levels and even have real gardens and plants. Wildlife would be extinct, save for a few robotic simulacra in the Imperial Zoo. Ironically, you would have to go to the Outer Colonies to see some animals that are extinct on Terra.
An asteroid hit the earth and blanketed it in ash for ten thousand years, a force many times bigger than all the nukes humanity could ever hope to build, and life still thrived eons later. The Earth and nature doesn't need saving, we need saving.
Don't forget that we're still apart of the ecosystem and "nature" and subject to every single one of its laws, including the biggest one: adapt or die.
That's not even the worst one, before the dinosaurs a large volcano in What is now Siberia errupted, throwing Earth's climate into a catastrope, the oceans became stagnant and putrid, belching poisonous gases from anaerobic bacteria across the land and sea, an estimated 90% of all life on Earth was smothered by the event.
It's called the End Permian extinction and it's the closest life on earth has come to being snuffed out entirely. Though for some reason it's forgotten about a lot.
or getting booed, saw that happen once. I don't think i'll ever forget it. i literally came armed to my own wedding because No One was going to get away with booing at my wedding. But hey, to each their own insult.
In a million years we'd have had a Dyson sphere for nearly a million years and colonized almost the entirety of the galaxy already.
We unfortunately wouldn't have colonized Andromeda quite yet though.
Any utopia first requires the basis of free energy. Dyson spheres are the start and the logical first outcome for any sufficiently advanced civilization. Fusion reactors being used as needed where we can't donate from the former.
The rest is all politics. The vast majority of people are good. When everyone isn't fighting for the same resources, the population of earth stabilizes in 2100 to about 11 billion people.
The growing pains until then through space colonies and terraformers will be admittedly rough though. Space radiation and the classism in that vacuum will be terrible for the poor and disenfranchised.
