That's good, but I have some issues with Pentti Linkola. Saying that he would push a button so that millions of people would die is just cruel. Millions of innocent lives would be sacrificed, only to be replaced later and the population growth would not cease, since the human population is in the billions (I don't know if it has reached 7 billion yet). I'm sure some murderous, criminal scum would be eliminated, but so would be passionate, hard working, honest and intelligent people, and innocent children.
Forced sterelization on the other hand, is a completely different thing,
