OK, I'll bite.
Unless the earth is forcing humans to industrialise, it's just a case of cause and effect (taking the accepted scientific viewpoint).
But, if we ignore human effects all together, and just focus on cycles, then again, you appear to be giving the earth some sort of purpose. For
example, ice-age cycles are just a natural response to changing variables.
You seem to be taking a very teleological viewpoint here, almost giving the earth mind and purpose. If I fall off a ocean liner into the sea and
drown, it's not because the sea wants me dead. I think they call this line of thinking 'promiscuous teleology'.
Now, I think such cycles contribute to the dynamic nature of life on earth, but there is no underlying purpose in things like ice-age cycles and El
Ninos.
Unless you are a pagan-type I suppose...
