"各種死物、生物都是互生共生"
Typically there is extinction wave. Organism is only related but hardly 互生共生.
(Think dinosaurs among the thousands of other examples.)
-------------------
By the way, we are already sitting at a "natural" extinction wave right now. Even without human intervention, many species will be wiped out on this one.
Life is more robust than may "environmentalist" (non-science based ones) would like us to think. |
