As I replied in another thread:
"My final answer to all of them is "YOU FIRST!! Set an example for the rest of us. Sell your car(s), quit flying, disconnect from the grid, quit wearing, eating or drinking anything even remotely processed by fossil fuels or uses plastic, and disconnect from the telecommunications network."
To which I'll add:
" If you also advocate human extinction, again, YOU FIRST! Set the example by taking yourself out of existence"
