Fish from all over the world, from deep in the sea, wind up in countries from Germany to Japan. That is just crazy.

It's baffling why the issues relating to climate change - [which] have far more obvious and tangible and much more clear-cut evidence about the cause - have been slower for people to accept as a given.

Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.

If somebody dumps something noxious in my back yard, the dumper is the last one I would call on to repair the damage.

The oceans deserve our respect and care, but you have to know something before you can care about it.

If Darwin could see what we now see, what we now know about the ocean, about the atmosphere, about the nature of life, as we now understand it, about the importance of microbes - I think he would just beam with joy that many of the thoughts and the glimpses of the majesty of life on Earth that he had during his life, now magnified many times over.

The climate has been changing. Of course it [has]. Evidence throughout history, [which] we can assess, especially during human history, shows there have been ups and downs. But the last ten thousand years have been relatively stable compared to now.
