Some Scientists Estimate That Over Half of the World's Rainforest

Some scientists estimate that over half of the world's rainforest has already been lost, mostly due to human activities. What would you predict as a consequence of the massive loss of plant life?

A) a decline in atmospheric carbon dioxide
B) reduced incidence of flooding
C) an increase in atmospheric carbon dioxide
D) a decline in soil erosion
E) a drop in average temperatures worldwide Areas of rich vegetation, such as rainforests, help keep carbon dioxide levels in the atmosphere relatively low. Thus, the loss of rainforest may contribute to global warming.
