[ Sorry, but for once I'd like to raise this here ...]:

well... how many "trees" does that cost every time you push?
I guess it will be less than one, but I'd also guess it be more
than 1% of one.. and even if that was more than reality, ...

I hope you are all aware that even though this looks "free", all
this mostly unnecessary (rebuilding some of the things *every*
time from scratch, downloading lots of stuff, even though from a
closeby server) traffic and server run time will partly be paid
by the kids and grand kids of people living in Bangladesh,
Polynesia, ... (and maybe even in say Amsterdam)
Global Warming *is* a threat, and we living in rich nations letting run
more and more computer networks and servers (cooling, heating,
gray energy including lots of CO2 produce by building construction, ...)
does add to it.

[[[yes, I may be partly wrong,  and
    no, it's a loss of time if we start a flame/mud/... war here about this;
    just consider it a small outlier voice ...
