Unlike your fish tank, in nature, fish eat each other. When the population of a species gets too low, it will die out.

Species are going extinct because of habitat loss and warming. I feel deeply responsible and think about it every day.

I always felt that if we ever encountered an alien species, they wouldn't look like us or even be humanoid, like 'E.T.'

The human species really could have faced global thermonuclear war. During seventy years of Cold War we grew used to it.
