ازدیاد جمعیت انسان

ازدیاد جمعیت انسان زمانی رخ می‌دهد که تعداد جمعیت انسانی در یک گروه از ظرفیت مکان اشغال شده توسط آن گروه بیشتر شود. ازدیاد جمعیت می‌تواند به صورت بلندمدت هم در نظر گرفته شود؛ زمانی که جمعیت به دلیل تخریب و استفاده از منابع تجدیدناپذیر نمی‌تواند منابع خود را تأمین کند و محیط زیست طبیعی توانایی پشتیبانی از جمعیت را ندارد.^[۱]

When its population can not be maintained without rapidly depleting nonrenewable resources [39] (or converting renewable resources into nonrenewable ones) and without decreasing the capacity of the environment to support the population. In short, if the long-term carrying capacity of an area is clearly being degraded by its current human occupants, that area is overpopulated.
