Gluttons
Humans evolved in times of scarcity. For example, at the peak of the last ice age around 70,000 years ago, it is estimated that only a few thousand members of the species were extant.
It is no surprise therefore that we are by nature gluttons; we evolved to make hay while the sun shines.
Through the application of technology and complex social systems many of us are now full time gluttons. And we are now staring at the abyss; the end of resources.
We need a solution to this if we are going to survive as a species. And by this I mean biological control of our natural gluttony.
