One of Eric Pianka’s favorite sayings is “What good are lizards? What good are YOU?”.
Well Eric, I’m a contributing member of the species that is developing the ability for the earth’s ecosystem to get off the third rock from the sun and secure a foothold on other worlds in other solar systems so that when this rock gets baked it won’t be the end of the line for life.
The big picture, Eric, is that if life is confined to this planet it is a goner. Planets you see are things that are born, exist for a while, then die. If the life that’s on them doesn’t relocate itself then it dies too.
If you look at the core activities of living things it doesn’t take a PhD in biology to note that they are born and consume whatever resources are necessary to reproduce and continue their kind. Looking at the earth’s ecosystem as a whole, how is it going to reproduce and continue its kind beyond the time that the earth/sun system is friendly to life? Simply put, it acts like all life acts and finds a way to get to greener pastures and it will consume whatever local resources are necessary to achieve that goal.
That’s where we come in, Eric. A lizard doesn’t build scientific instruments that can detect habitable planets around other stars and a lizard doesn’t build spacecraft that transport earthlife to habitable planets around other stars. Life on this planet can spread through the galaxy through my species and if lizards largely disappear from this planet it won’t effect the big picture. If we use up all the resources on this planet but manage to get the seeds of life moved to another planet in the process then we’ve done our job and the earth did its job. That’s all that matters. This planet is doomed one way or the other. The important thing is that life doesn’t die when the planet dies. That’s what good I am and that’s why lizards are not important in comparison.
Your narrow minded view, Eric Pianka, isn’t fit for survival.
