Well, it’s not my opinion, it’s historical fact and scientific consensus. In the not distant future, as the earth loses itsprotective magnetic field (accelerating rapidly now as the poles shift ) a good sized solar flare (that happen on s fairly regular basis , last earth directed one was carrington event) will knock out all electronics. Even fema acknowledges this with a 4-10 year schedule to restore power. Our food/transport/monetary systems having collapsed will cause much of the population to starve or fight each other. Unless you have prepped as well as the government with massively stocked underground bases, likely you will die too.can you feed your family and everyone nearby with zero mechanical help? No bought products like fertilizer? Most the people will die. This is before we discus the pole flip and what that will do to the world. ( go check pole movement before you answer.) I don’t condone killing anyone, but after nature dies it because we’ve all become complacent, it’s not terrible advice to aim for a population that isn’t stressing the natural food production capability of the planet ( likely with unpredictable weather which crops don’t like).
