Not to worry
For a time, I too, was worried about self-important self-appointed zealots working feverishly to rectify a problem they didn't fully (or nearly) understand with un-tested methods and unknowable consequences for the entire planet.
Then I began seeing articles about CRISPR/Cas9 (gene editing for dummies -
https://en.wikipedia.org/wiki/CRISPR/Cas_Tools) and was comforted to know this will solve all our problems well before we self-destruct the environment we inhabit.
Once these fools (humans) begin fiddling with the human genome in a substantial manner, '12 Monkeys' and 'I Am Legend' are going to look much more like prophecy than science-fiction.
But, anyway, it's a lovely day outside, isn't it?
