Water is at the center of every chemical reaction, and therefore should be the earth's most precious gift.

Green chemistry is replacing our industrial chemistry with nature's recipe book. It's not easy, because life uses only a subset of the elements in the periodic table. And we use all of them, even the toxic ones.

The truth is, natural organisms have managed to do everything we want to do without guzzling fossil fuels, polluting the planet or mortgaging the future.

We're basically this very young species, only 200,000 years old. We're one of the newcomers, and we're going through the same process that other species go through, which is, how do I keep myself alive while taking care of the place that's going to keep my offspring alive?

There are three types of biomimicry - one is copying form and shape, another is copying a process, like photosynthesis in a leaf, and the third is mimicking at an ecosystem's level, like building a nature-inspired city.
