Arguments Against Both Climate Change and Overkill
Detractors have asserted that neither the overkill nor climate change hypotheses can explain several observations. Among these are the observation that browsers, mixed feeders and non-ruminant grazer species suffered most, while ruminant grazers generally survive However a broader variation of the overkill hypothesis may predict this, because changes in vegetation wrought by anthropogenic fire preferentially selects against browse species. Because of perceived shortcomings of the overkill or climate change hypotheses alone, some scientists support a combination of climate change and overkill.

“Yesterday the Electoral Commission decided not to go behind the papers filed with the Vice-President in the case of Florida....

“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
“The average Southerner has the speech patterns of someone slipping in and out of consciousness. I can change my shoes and socks faster than most people in Mississippi can speak a sentence.”
