What do you see as the greatest threat to our world, our society, or mankind in particular? Any or all...

These two knuckleheads.

I can encompass all of these with three words:

Man's misplaced priorities.

As the only creature to ever exist on this planet with the ability of self-determination, we humans are destroying the planet in the name of stubbornness and greed; crippling our societies in the name of belief and vanity; and killing each other en masse due to our ignorance and hate.

Hi, Toxic Hairball...here is how I see it...

Fear

Greed

Rage

Space aliens that drink Mtn. Dew and ride motorcycles.

Police brutality.

White

Black

Only to them blue matters

Civil war will happen

Because of the corruption of the police-

I'm ready- are you ?

Intolerance of others. It leads to hate and violence.

1. Mankind

2. Disease

3. Mankind

Mankind

Enormous question, concise answers, all hovering around the same theme. I'll just add one word. Indifference.

Humans are not a threat to the world, only to each other, as George Carlin said, mother earth will shrug us off like a bad case of fleas.

However, until that time, our ignorance, greed, pursuit of power and immortality could cause quite a lot of damage.  "Enough" doesn't appear to be in our vocabulary. I am not fooled, those in positions of power do not give two hoots about "saving the planet," and if they were their plan would consist of getting rid of more of us, not giving up their private jets, and cravings for a larger economy to keep them in their accustomed lifestyle.

Lack of education, specifically in understanding that the behavior of people in a democracy does not always include behaviors that will ensure the survival of the democracy.

It was put this way more recently "Complexities of technological, diplomatic, and military issues mean that 82%of the electorate cannot be expected to reach an informed decision."

As William F Buckley, Jr. Once observed:  "How does one know that we are entering a Dark Age?"

Racism

Hate

Greed

😔

Our apparent ability to actually enjoy the state of ignorance.
