I've always found that ironic that people think that chemicals are man-made entities that just contaminate an otherwise chemical free natural world. But the truth is that nature is alive with chemistry. The colors of birds, the flavors of spices, the fragrances of flowers, the coatings, on leaves, the lubricants of our joints, those are all nature's chemistry. And it's nature's chemistry done in life-friendly ways. Nature does chemistry in water, at ambient temperatures and pressures, and using the resources that are just within reach. And nature has to do that because nature can't do its chemistry somewhere else. It does it right where it lives and it can't poison its habitat. So when we're making new colors, new fragrances, new vitamins, any types of chemicals that are part of our daily life, we should ask nature, how does nature do this chemistry?
