I see, well I try to look at the bigger picture generally, in terms of the effect we have on the planet, how my small actions affect people as a whole ( butterfly effect if you like), but then people are also selfish, so despite the fact we're overpopulated as a planet as a whole I'm going to have children, but I like to think that a couple of extra people can be offset by the good we will all do the planet because we do actually care, but in that sense we can rationalise our own negative actions as being okay, so it's a double edged sword.
