No worries, doesnt matter how successful we are in the end, the world will end anyway. Doesnt matter if you die alone or have a big family. They will all die soon enough. As we contaminate the land and seas, we can all agree as far as we know we are trapped here, you and I with no way to leave. Even if we did leave it would be short lived. There is no purpose. Many young adults with their lives ahead of them die every day and we only care about the ones we know. Suffering is infinite and happiness is fleeting and can always be drowned out by being cognizant of the terrible suffering occurring every second of every day.
Edit: I'm joking fyi
