Yet here we are, the biosphere is changing, 7 billion humans, record numbers of animal extinctions and the excretions of the record number of humans ISN'T and CAN'T be a factor...oh, NO, why the hell NOT? It's pretty obvious and has had effects any way you want to cut it. I have seen the changes, the extremes in weather, the warmer dryer effects and the dying pine forest in Colorado due to pine beetles loving the warmer climate. Don't dare to argue with me unless you are an idiot.
And WHO SAYS that the billions and billions of seaweeds and grass shoots and flies and crickets and birds can't be a factor!?
Yeah!
