There is only one ethical question to humanity.

When it comes to ethics, we can assume this or that, but the main question here is:

How long our specie will survive?

And with ethics, this is our primary question, because the specie itself should do everything and anything to survive longer.

The individual is instantly dead without the specie itself. Because he can’t reproduce when there’s no one.

Every single death is like death of the specie.
