More CO2 might be good for us in the long run

[Carsten Wiethoff]

Whether you believe that human activity is responsible for global warming or not, you must concede that we are, in fact, the only species capable of making a global difference in CO2 levels, or in rising temperatures, or sea levels. That inescapable fact imposes on us the duty to do so, for the benefit of ourselves and our descendants, as well as the vast remainder of the teeming bulk of life on this planet over which we have dominion.

Or, we can continue to foul our own nest until we die.

I think it would be more correct to say that we are the only ones that could do so consciously. So far we have done it without conscience, undoing the effect of all the life forms that formed the carbohydrates in the first place.
I still find it interesting that by far the most carbon on earth is bound in calcium carbonates produced by mussels, snails and other animals. Maybe improving the living conditions of such animals could have an effect on CO2 in the long run, given that our goal or duty should be to keep conditions
stable. At least calcium carbonate is harmless and even very useful for many applications.
