Human being amaze me. I thought about this recently. We are a species that can be fruitful and multiply, but also put ourselves out of business.
Two ways come to mind:
1. Global Warming. That one is still constantly studied. The dinosaurs weren’t capable of creating what put them out of business, but we can (though Mother Nature can still trump mankind any day, any week).
2. I forgot the title, but I was reading a book recently that said the world population is dropping. I don’t know about other species, but humans can choose, NOT to have children.
Humans never cease to amaze me.
