What is the greatest threat to the survival of the human species?

Answer 1

The most often cited "greatest threat" is that of nuclear war. The so-called "nuclear winter" effect would render the planet uninhabitable for humans.

Isn't the greatest threat to the survival of the human species the human species itself? I mean, we're constantly threatening to drop bombs on other people which would inadvertently harm ourselves as well. To make a quick buck, industries that are run by people are willing to take short cuts which increase obesity, cancer, early onset of puberty, as well as any other illness one can think of. We're the greatest threat to most other organisms living on the planet and because of the things we do we're deteriorating nonliving factors like the ozone and water sources too. The list of crap we do and the crimes that we pull individually and collectively is outrageous, not to mention lethal (in most cases, eventually) Seriously, we're scary organisms.

Answer 2

Some of the greatest threats to the survival of the human species include climate change, nuclear warfare, pandemics, and biodiversity loss. These issues have the potential to have catastrophic consequences on a global scale and require urgent attention and action to mitigate their impacts.
