Its even worse than that. Literally nobody has done as much as needs to be done.

And far too many (at least in my country) seem to be saying “we are such a small drop in the ocean compared to (insert larger country here), so why should we go first?”.

It’s frustrating to see how badly we’re fucking our children and grandchildren through laziness, denial and greed.
