A painting is nothing more than light reflected from the surface of a pigment-covered canvas. But a great painter can make you see the depth, make you feel the underlying emotion, make you sense the larger world. That, too, is the power of science: to sense and convey the depth and dimensionality of nature, to glance at the surface and to divine the shape of the universe around us.

Whether on'e special emphasis is global warming or child welfare, the cause is the same cause. And justice comes from the same place being human comes from: compassion.

Any honest inquiry into the reality of nature also yields insights about ourselves.

To save the seas, we can eat sustainably and be conscious of the seafood we eat.

Try to cut down drastically on plastic. Recycle. Use less energy and more renewable energy. We can all live better by doing better for ourselves and the sea!

If you ask the fish whether they'd rather have an oil spill or a season of fishing, I wouldn't be surprised if they'd vote for another blowout.

But one doesn't wait for a revolution. One becomes it.
