In musical terms, cross-pollination is like adding harmony to melody - it's the mix of the contrasting tones that adds the richness and expressiveness.
Perhaps, in contemplating the beauty of what these creatures do, we might also consider the necessity. Most know that life as we know it would be impossible without bees. About 90% of our crops would fail us without them, not to mention all the animals that would die of starvation. Destruction of wildflower habitat, as well as the use of pesticides, is reducing the bee population in the world at an unsustainable rate. In other words, we will not be sustained at this rate.
Let's sustain ourselves, and our buzzing friends, by living with them - and ourselves - in greater harmony.
