Definitions and quotes

Population
In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas.
Population
Population, when unchecked, increases in a geometrical ratio, Subsistence, increases only in an arithmetical ratio.
Thomas Robert Malthus An Essay on The Principle of Population, Chapter I, paragraph 18, lines 1-2.
Population
If this were true, the population of the world would be at a stand-still. In truth, the rate of birth is slightly in excess of death. I would suggest that the next edition of your poem should read: “Every moment dies a man, every moment 1 1/16 is born.” Strictly speaking, the actual figure is so long I cannot get it into a line, but I believe the figure 1 1/16 will be sufficiently accurate for poetry.
Charles Babbage, cited in: New Scientist, 4 December 1958, pg.1428.
Warming brought on by climate change is causing the icebergs in the Antarctic to drift towards the shore and cause fundamental damage to the rich sea bed ecosystem. The icebergs are scouring the sea floor as they drift close to shore of the west Antarctic Peninsula (WAP). This movement is fundamentally altering the rich sea bed ecosystem.
