Then you've admitted the only point I care about here, which is that getting personally panicky about those things would have been a waste of time. Doom is not certain. People do in fact do things in reaction to problems.
"Did it occur to you that just because you live an insulated life, that these disasters are actually happening right now?"
Read what I wrote again with an eye towards answering those questions, because the answer is there. The Earth is positively saturated with problems... but that's not actually a new state of affairs, despite what youth may think and/or certain people may have told you.
You are establishing that problems exist. That is not the question I am answering. I am answering is doom inevitable? And the answer is simple: No. Do not live hopelessly. Do not plan for your future life as if we're all going to be dead in 10 years inevitably because of environmental disaster. There are many disasters in your future with non-zero probability, but living as if they have already occurred just moves them into the present with 100% probability. That's not a win.
In terms of reading my mind, you'd be doing better off if you first read my text, instead of what you assume my text is going to say. Or trying to figure out which bogeyman to associate me with so you can stop thinking and start emoting. That's not a healthy psychological pattern. Who taught you to do that? What benefit do they get from it? Are you benefiting from it? (Hint: No.)
