IE: the evolutionary trend towards k selection vs r selection in orcas is backfiring during the current mass extinction event that is putting excessive pressure on their population numbers. In times of extreme population stress and environmental decline, passing on genes is too uncertain even with large investment in offspring and so a lot of effort is wasted compared to producing more offspring but putting in less effort for each.
