Bob Zannelli has it exactly right in his message below.
There is no "should" in science, nothing that humans "should" be doing
regarding transferring carbon from here to there. It is only about what
we *are* doing. The planet couldn't care less (of course), and will take
care of itself, as it has for 4B yrs. The issue is whether the human
race (+all other species) can keep up with the changes they are
creating, or not.
