Biomes on earth have exhibited changes throughout history that have been caused by a variety of factors. over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation. what factor is likely most responsible for the changes observed in the world’s rainforests? a. volcanic activity. b. human activity. c. temperature changes. d. solar eclipses.

b. human activity

Explanation:

A reduction of more than one third the total acreage of tropical forest in the world is not likely to be due to volcanic activity which is not so widespread in the present time. Temperature changes although important, are slow in their effects and are more likely to cause a change in forest cover rather than a dramatic loss. Solar eclipses are not known to cause deforestation. Human activity however, is known to cause important loss in forest acreage due to land use change, mainly to agricultural land.
