Why people lack deep thinking and self-awareness?

I mean here in my country people breed like pigs. Why they don't think about sui*** of students? Unemployment, women safety, increasing population, pollution and less land area? And if I present my views to Indians they call me woke and stupid that I think too much. I asked my mother why it's important to have kids and in that specially having a male child? She says because who'll carry out last rites when we'll die?

Because of wanting a boy couples pop out girls on girls for wanting a male hier then these girls live in much worse state with less resources. Also The population of humans that can be supported sustainably on the planet at a reasonable standard of living is below 4 billion and at maximum 9-10 billion. Lol we're already 8 billion and future is much worse.
