Re: Humans like locusts
I find the constant use of "Humans" as a single entity description.. simpleminded to the point of being childish.
The human race is divided into multiple cultures - more than races, with different ethical values and priorities, and what is desirable in one is frequently considered rank stupidity in another. These value differences exist not only between nations and ethnicities but also within them, as the fracturing of the USA has been rubbing into our faces recently.
Bearing this in mind, each of us should act to support what they personally consider worthwhile, -be it interplanetary colonization with or without a 'z', or back to nature environmentalism, militant nationalism or economic or religious feudalism.. whatever.
Stop tying to fix everything and just do what you can, knowing that other people with divergent ideals will be actively opposing you.
If Musk can make some progress towards a Mars colony, good on him, and best wishes for everyone involved (plus the expectation they will all die horribly but hopefully provide useful data in the process)
If some one else wants to restore Earths disappearing icecaps and rainforests.. good for them too.
Personally I am not a fan of more coal/oil/gas development but there are people who are investing their futures in that... and as such they deserve to die in a fire.. but they have reasons which are valid for them.
