The climate is changing, regardless of the cause. Populations of animals and plants will have to respond accordingly. Some will not be able to respond as rapidly as their environment changes. Those populations will wink out. Casting blame, tinkering with existing management strategies or denial will not change the outcome. The root problem is that there are already too many people on this planet.
Denying that huge readjustments in natural systems are not going to occur--many of them much more quickly than we can imagine--probably will not have much more effect on the final outcome than adopting any (or all) of interventions that are potentially available to us .
