> but recent news has made it clear to me that travel is one of the human obsessions that is destroying this world and that the future will not happen:
If you think that impending climate change (/climate catastrophe) is significantly impacted by the "human obsession" of travel, you are drinking someone else's kool-aid and pulling wool over your eyes as to the real causes (industry greenhouse gas emissions, industry and non-industry energy generation, and agriculture).
>My advice, for all age groups, is to enjoy what you have now and don't have kids-
My advice for all age groups is to take with a massive grain of salt what a 23-year old suggests to you, perhaps going as far as to completely discount any "life advice" given by this demographic. And I'd also suggest to make a decision about having or not having children based on your life circumstances rather than some absurd claim (coming below) that the world sucks.
> the world even 10-20 years from now isn't one worth living in.
We get it; you're a pessimist. People have espoused this same sentiment for decades (actually, centuries or longer).
