That sounds a bit silly though - as you said, a false choice. Surely you wouldn't want to pave over the whole continent. There are other ways to save the children than to destroy everything. It's also a question if humans have to expand everywhere.

If it all is such a no-brainer for you, I wonder what other choices you make in your life to save lives in 3rd world countries? For example CO2 consumption? To be honest, I don't buy your no-brainer attitude.
