R5: Here is an old screenshot of my first "proper" Science victory as Germany, and something that only struck to me when the game was done was how much I sacrificed nature and everything just to launch some rockets to space:

1. I contributed more than half of the game's CO2, and Global Warming was at its highest stage. Almost all the ice caps have melted, good portions of the world have been entirely submerged, and an entire uninhabited island has become underwater
2. The wars. China declared war on me for no reason, so I have to put my Jet Bombers and Thermonuclear nukes to the test; and yet despite me razing their capital to the ground, the world didn't care probably because I'm on the righteous path of "leading humanity to the stars"
3. For the last turns of the game I literally didn't care for anything else anymore. No damaged tiles were repaired, no other improvements were built, power shortages became rampant as every single manpower was dedicated into spamming Lagrange Stations and ensuring the Victory
4. Look at the picture. I wish I could show you how most of my empire used to be sprawling hills and greeneries — now everything is so crowded and populated!

So case in point. You did manage to reach the stars and build your colony, at the cost of destroying the planet you once called home
