The 114 threatened sites, virtually half the total listed by UNESCO, provide food, water, shelter and medicine to over 11 million people -- more than the population of Portugal, according to a WWF-commissioned report.
The sites are meant to be protected for future generations.
"Despite the obvious benefits of these natural areas, we still haven't managed to decouple economic development from environmental degradation," WWF director general Marco Lambertini said in a foreword.
