Where Have All the Browsers Gone?
Where Have All the Browsers Gone? New research indicates that the decline in browser
species (species that eat leaves off trees) over the last 20
million years has been gradual and stemmed from a number of causes.
One of the primary causes is thought to be a decline in the amount
of CO2 in the atmosphere, which led to the death of many of the
tree species that browsers grazed on. 5 NOVEMBER 1999, P. 1071-1073
