How did the change in CO2 levels at the end Permian influence other Earth
systems?

(A)formation of large ice sheets caused falling global sea levels, destroying marine
ecosystems

(B)increased forest cover in terrestrial environments led to greater weathering
rates, drawdown of CO2, and glaciations

(C)I fresh water from melting glaciers shut down thermohaline circulation in Earth's
oceans, which caused
widespread anoxia

(D)O increased 2 led to the direct death of plants and animals because they could
not handle the change in atmospheric gasses
