World population - Wikipedia Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent
Mass Extinctions and Their Relationship With Atmospheric . . . Toward this end, it has been estimated that Earth harbors 100,000 genera and 8 7 million (±1 3 million) species (Mora et al , 2011) At an annual increase of 2 ppmv in atmospheric concentration of CO 2 , current human activities will raise atmospheric CO 2 from 421 to 441 ppmv in the next decade, corresponding to an increase in the loss of
