I guess there is a time and place for everything.

If the Earth is evolving, and I think it is, I would hazard the guess that the makeup of the biosphere must evolve to meet the new conditions/needs. It appears that the thin biological "skin" of the Earth plays a role in transforming energies coming in from other cosmic concentrations, especially the Sun.

The Sun goes through massive changes (if compared to our little planet) and so our planet must shift and transform to adjust to the change in energy from the Sun (which is also evolving). One of the ways is by adjusting the qualities, quantities and balance of life on its surface.

To think that humanity is "responsible" for global warming gives far too much importance to its actual circumstances and place in the grand scheme of things. Humanity is quite as passive as the rest of the biosphere in this regard, as are most individuals within humanity.

Some individuals within humanity can consciously participate in producing and transforming the energies required of them by Great Nature and then produce a little more for their own individual evolution. But that is not the fate of humanity as a whole which simply passively and unconsciously serves Great Nature.

Darn, @sweetsssj, you made me go and think. I have to be careful around you :-)
