An ecosystem without carnivores would produce tremendous suffering, being constantly just under the Malthusian threshold for collapse. Even if it didn't start out that way, adaptation to a predator-free environment would be rapid.
If we can get sustainable life going on other planets we can solve this problem as well.
Is a life without suffering even a life as we know it? and, furthermore: Is suffering as a negation not necessary for any kind of happiness or joy in the first place? those are two things I am inherently convinced of, I truly believe there can be no happy life without suffering, for happiness without its counterpart will always devolve into sterility, and that is arguably worse than suffering.
I don't agree with this at all. It's just a failure of imagination to think we need the bad with the good. IMO suffering always degrades happiness. Being slighted by someone rude may help you appreciate kindness but true suffering, having your trust betrayed repeatedly doesn't lead to more joy when people are reliable, it creates a script where true trust is impossible.
Who are the most joyful humans? Children of course. The same ones who have suffered the least. Children who suffer much in childhood generally have a reduced capacity for joy.
A child has the capacity to appreciate a beautiful garden EVERYDAY, you don't have to lock him in the closet to appreciate it, he just appreciates it.
Reducing suffering in the human mind is a technical problem. We didn't evolve to be joyful, we evolved to survive, get laid at least a few times & create offspring. Our default state is anxious, craving, etc.
Really terraforming our minds is where it's at. Designer humans won't be about getting a baby blue eyes or brown hair but humans with increased resilience, focus & confidence, better brains in short.
People with a higher default happiness state will be more productive, they won't be susceptible to fear mongering politicians, they'll suffer less addcition. Life with joy turned up & suffering turned down is the goal of any human endevour anyway.
but one could, in theory, devise a system that does not need carnivores in order to stay stable is what El_Mac was arguing, and you missed his point by a mile
Yeah, just tweak evolution so creatures don't always maximize reproduction when the coast is clear of predators.
Reality is wack, we need to better it. Just because we live in a world of suffering & predation doesn't mean we have to accept it. I appauld those who want to expand life onto other planets for the spirit of "if you can, we should" however unlikely I think we will actually be able to do it anytime soon (if at all).
