Do we value keeping fish alive more than keeping old people alive via power-hungry air conditioning? There are millions of simil…

Seriously, a better way would be to start doing 5-whys on this, instead of going for "non-objective things". A quick attempt will tell you that we care for both ecosystem and power, but depending on the local context, we might care more about one or the other. Maybe we can impo…
