Which one is "shooting ourselves in the foot"? Pumping more nitrogen fertilizer in the environment or cutting it?
I think it depends who is "we" and what's the timeline for shooting ourselves in the foot, short term or long term.
In both cases it sucks. I have a preference for the better long term strategy, at least I don't have the impression or driving into a wall (or I feel like we trying to swerve/break).
Some day it's hard not to feel overwhelmed, looking at the global prospective. Keeping our planet habitable will require us to:
* Sacrifice individual benefit for the common good
* Trust each other
* Think long term (like multiple generations)
All things humanity has a horrible track record at.
That does not put me in an optimistic mood.
On the up side, if we kill everything including ourselves maybe in millions of years the next intelligent race will find remnants of our apocalypse and learn from it? =)
