The most urbanized regions are Northern America (82%), Latin America (81%), Europe (74%) and Oceania (68%), with Africa and Asia having nearly 90% of the world's 3.4 billion rural population. [155] Problems for humans living in cities include various forms of pollution and crime , [ 156 ] especially in inner city and suburban slums .
For instance, modern humans are Homo sapiens sapiens, or H. sapiens sapiens. In zoological nomenclature, higher taxon names are normally not italicized, but the Botanical Code , the Prokaryotic Code , the Code for Viruses , the draft BioCode [ 4 ] and the PhyloCode [ 2 ] all recommend italicizing all taxon names (of all ranks).

In the Philippines, they are also called alamang and are used to make a salty paste called bagoong. Krill are also the main prey of baleen whales, including the blue whale.
In the past ctenophores were thought to have only a modest presence in the ocean, but it is now known they are often significant and even dominant parts of the planktonic biomass. [221]: 269 The phylum has about 150 known species with a wide range of body forms. Sizes range from a few millimeters to 1.5 m (4 ft 11 in).
