Dare to be an optimist.

I started out wanting to be a naturalist. My obsession in my youth was with bird-watching. I collected things, I spent a lot of time outdoors. I only vaguely realized that science was a little more than natural history, but by then I was hooked.

China has led the world in new tree planting; in fact, over the last several years, China has planted 40 percent as many tress as the rest of the world put together. Since 1981, all citizens of China older than age eleven (and younger than sixty) have been formally required to plant at least three trees per year. To date, China has planted approximately 100 million acres of new tress. Following China, the countries with the largest net gains in tress include the U.S., India, Vietnam, and Spain.

That's part of the policy: To keep switching gears.

In science fiction, we're always searching for new frontiers. We're drawn to the unknown.

I opted for a freelance writing career. I was lucky enough to have the means to do it.
