It has been estimated that 139.2x10^6 m^2 of rainforest is destroyed each day. assume that the initial area of tropical rainforest is 20x10^12 m^2.
a) What is the exponential rate of rainforest destruction in units of 1/days?
b) If there were 24.5x10^12 m^2 of tropical rainforest on Earth in 1975, how miuch tropical rainforect would be left on Earth in 2015 if the exponential rate of destruction determined in part (a) stayed constant over this time interval?
c) If tropical rainforests remove 0.83 kg (C)/m^2-year from the atmosphere, how much less carbon [kg(C)] would be removed in 2025 compared to removed in 1975?
