The introduction of Bison

The introduction of Bison- post slaughter- era:
 -the ghost dance of the 1880s anticipated the reappearance of bison in full life/measure. Bison numbers plummeted from 7o billion to  less than a thousand. The math speaks for itself. The broader ecological system is that that the introduction of bison cannot regulate the whole ecosystem by themselves. You see the antelope and deer keep the plant species balanced  by their concentration on shrubs and forbs...however, paralleling the history of beef, as the bison market matures, overall damage to vegetation resources....escalate..... however central to present market limitations is the dichotomy between the lower production cost of bison and the three times prices found in market place. The capitalist principle still operates bison have a greater profit margin than cattle...The largest remaining conclusion is to develop the management and marketing pathways that will avoid past mistakes...the ecological and economic potentials provide the impetus to provide the bison a come back pathway...

2- climate emission- control-
After researching and providing presentation in class nothing has changed.  In order to stabilize CO2 concentrations at about 450 ppm by 2050 global emission would have to decline by 60 % by 2050.
