Early human beings... filled a special ecological niche: they were carnivorous primates of the African plains. ...When agriculture permitted the increase of population density, game was no longer abundant... carnivorism remained a basic dietary impulse, with cultural aftereffects that varied according to the special conditions of the environment in which the society evolved.

The very general occurrence of the homosexual in ancient Greece, and its wide occurrence today in some cultures in which such activity is not taboo suggests that the capacity of an individual to respond erotically to any sort of stimulus, whether it is provided by another person of the same or opposite sex, is basic in the species.

Animals' taste systems are specialized for the niche they occupy in the environment. That includes us. As hunters and foragers of the dry savannah, our earliest forebears evolved a taste for important but scarce nutrients: salt and high-energy fats and sugars. That, in a nutshell, explains the widespread popularity of junk food.

Everything we think about regarding sustainability - from energy to agriculture to manufacturing to population - has a water footprint. Almost all of the water on Earth is salt water, and the remaining freshwater supplies are split between agricultural use and human use - as well as maintaining the existing natural environment.

I find that because of modern technological evolution and our global economy, and as a result of the great increase in population, our world has greatly changed it has become much smaller. However, our perceptions have not evolved at the same pace we continue to cling to old national demarcations and the old feelings of 'us' and 'them'.
