A recent review, 28 July, pub­lished in the jour­nal Marine Ecol­ogy Progress Series says bio­di­ver­sity is in con­tin­u­ous decline despite rapid growth of pro­tected land and marine areas worldwide.

Bio­di­ver­sity and ecosys­tem ser­vices are humanity’s life-​support sys­tem, deliv­er­ing pre­cious goods such as food, clean water and air, energy, min­er­als and ‘play­grounds’ to our advanced civilization.

Yet there is an increas­ingly well-​documented global trend in bio­di­ver­sity loss, trig­gered by a host of human activ­i­ties” Camilo Mora, one of the authors of the study, said.

we must get seri­ous about address­ing the growth in size and con­sump­tion rate of our global population
The lead­ing strat­egy in nature con­ser­va­tion to reverse ongo­ing losses in bio­di­ver­sity by cre­at­ing pro­tected areas and the suc­cess­ful enlarge­ment of these pro­tected land and marine areas over the years did not stop bio­di­ver­sity loss, unfor­tu­nately. In fact the rate of bio­di­ver­sity loss increased while the total area of pro­tected land and sea expanded. Thus, expanded des­ig­na­tion of pro­tected areas may not be suf­fi­cient, the sci­en­tists say, which under­pins the need to reassess world’s heavy reliance on this strat­egy. There have been some local suc­cesses, but on a global scale we have to change the approach. While efforts towards improv­ing and increas­ing the num­ber and/​or size of pro­tected areas must con­tinue, there is a clear and urgent need for the devel­op­ment of addi­tional solu­tions for bio­di­ver­sity loss, par­tic­u­larly ones that sta­bi­lize the size of the world’s human pop­u­la­tion and our eco­log­i­cal demands on bio­di­ver­sity. In other words “….. that we get seri­ous about address­ing the growth in size and con­sump­tion rate of our global pop­u­la­tion.” accord­ing to Peter F. Sale, the other author of the study.
