Additional Information: According to this quote from cinematographer Louie Schwartzberg, sex and love are survival tools, as we will defend and care for (and thereby prolong the survival of) beautiful things that inspire our love and lust. Schwartzberg is making this statement of the entire world of living beings, not just people; the forms of life Schwartzberg discusses in the TED Talk this quote is from are actually plants and the creatures that pollinate them.
