I came across a lovely film and a lovely quote today; passing on to share.
What motivates the pollinators? Well, their answer was, "It's all about risk and reward." Like a wide-eyed kid, I'd say, "Why is that?" And they'd say, "Well, because they want to survive." I go, "Why?" "Well, in order to reproduce." "Well, why?" And I thought that they'd probably say, "Well, it's all about sex." And Chip Taylor, our monarch butterfly expert, he replied, "Nothing lasts forever. Everything in the universe wears out."
And that blew my mind. Because I realized that nature had invented reproduction as a mechanism for life to move forward, as a life force that passes right through us and makes us a link in the evolution of life. - Louie Schwartzberg
