The ever - burgeon human population is an incredible line on global resources and the environment . It ’s been forecast that by the turn of the century,11 billionpeople will inhabit our planet . More food for thought , more water , more homes , more domain , more aesculapian resources are all function to be require to conciliate this staggering number . So it ’s logical to assume that the estimable fashion to take on this problem is to find a room to reduce population increase . Not according to a new study , at least .
As depict in the journalProceedings of the National Academy of Sciences , a dyad of researchers from the University of Adelaide used computer modeling onWHO and nose count datato look into how long it could take for a reduction in the human universe to positively impact the environment . To do this , they plugged in various different scenarios for population variety which allow for them to project the global universe throughout this century .
Thefindingswere unfortunately not exactly encouraging . Even if every land apply a strict one - child policy , the survey suggested that the human population would still likely hover around today ’s bod for the next 90 odd years . And a catastrophic mass fatality rate issue , removing almost a quarter of the population , would finally hardly make a dent either .
But by no means are the authors indicate that we should dump efforts to scale down fertility because of these findings . If we pursue family planning and reproductive memory education , then we could have hundreds of millions of fewer mouths to prey by 2050 . In addition , nations need to reckon of way to reduce our increase consumption of Earth ’s finite natural resource , and also focalize on ecosystem preservation . Ultimately , however , such measures are no warm fix and are n’t going to benefit citizenry alive today .
“ Global population has risen so tight over the retiring C that roughly 14 % of all the human beings that have ever existed are still animated today- that ’s a sobering statistic , ” lead author Corey Bradshaw said in anews - dismission . “ This is considered unsustainable for a range of reasons , not least being capable to feed everyone as well as the impingement on the clime and the environs . ” technical and societal foundation , he says , are the most fertile elbow room to lessen these wallop .
