The topic of the world's human population is in the news frequently. Many experts are concerned that the number of people in the world is reaching its maximum carrying capacity, or the highest number of people that the environment can support, while others argue that there is no population issue. You may want to check the population of the U. S. using the United States Census Population Clock on the United States Census Population Clock website. Also, the world population statistics have been provided in the data table below:

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
