I have better things to do at the moment than try to flood the planet with clones of myself like some type of sub-saharan African.  The other life on earth like whales and rats and whatnot matters as well.  Every human having kids just hastens the demise of all other lifeforms, so it's not like there's some benefit from western people attempting to adopt r-selection to compete with others that do when it's already a losing strategy in the short and long term in the first place.

The issue at hand is twofold:  

1)  K-selection technology has erroneously been handed to r-selection populations who could otherwise never have invented it, which only subsidized evolutionary dead ends.

2)  Globalization makes regional overpopulation that would otherwise sort itself out everyone's problem.  Instead of r-selection groups evolving towards k-selection and increase efficiency, they just outsource their deficiencies to maintain themselves in current state with less effort.

Since k-selection groups do not win in any way by converting to R, the only choice is to either completely remove yourself from globalism to stop subsidizing them, or actually go to war against the r-selection groups to prevent them from overrunning everything.

As for reproducing solely for the sake of reproducing, either way the sun will eventually go red giant and eat the earth.  Even if you believe you're going to get your genes off the planet before that happens, you still have heat death of the universe.  There is no way to win that game and achieve immortality unless you believe you can "transcend" into some other type of plane or whatever.  In such a case you no longer need to reproduce since reproduction is only needed if you plan to die in the first place, or if further rounds of selection process would actually be beneficial.
