Craig Kiebler Posted over 3 years ago Why do so many think that population growth is an important issue for the environment? Don't they know the facts of demographics? I agree with Janet, loss in biodiversity, land degradation and encroachment have increased the number of emerging infectious diseases (75% of which are zoonotic). Further, the impact of livestock and crop production increases the risk of food insecurity as well as decrease in individual economic development. As far as the demographics go, I would be interested in more focus on regional data, instead of overall global rates. Are the areas where population (i.e. births) increasing, also areas of limited/degraded land, decreased animal/crop production, poor nutrition, etc. What are the public health infrastructures like in these areas? Many of these regions are also hotspots for emerging diseases. In other words, the total global population density might not be the issue; instead, it might be more enlightening to look at regions of population growth and whether they also suffer other factors (e.g. food shortages, decreased production, poor public health infrastructure, education, etc.) that would make them significant to the global community.
