I don’t think it’s a question of amount of effort. Both undertakings would be monumental. It’s more so a question of what skillsets you have and what you’re more capable of doing.
In Canada, we had a third party nearly come into power a while back until we lost the leader to cancer.
It can work, but the most important part in making it work is building the movement so that everyone votes for the third party in the same election. There’s no point in just voting third party and complaining that no one else is doing it.

Context will tell you that we’re talking about losing access to water. If people won’t procreate because they don’t have water, it makes no difference if it’s because we are literally all out of water or if someone else is hoarding it all. In both cases, there’s no access to water.
You can also build a nearly straight railway going from California through Canada and Alaska all the way to China.
