This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

Unfortunately, nature is very much a now-you-see-it, now-you-don't affair. A fish flashes, then dissolves in the water before my eyes like so much salt. Deer apparently ascend bodily into heaven; the brightest oriole fades into leaves.

It is estimated that one-third of all reef-building corals, a third of all fresh-water mollusks, a third of sharks and rays, a quarter of all mammals, a fifth of all reptiles, and a sixth of all birds are headed toward oblivion. The losses are occurring all over: in the South Pacific and in the North Atlantic, in the Arctic and the Sahel, in lakes and on islands, on mountaintops and in valleys.

For better or worse, zoos are how most people come to know big or exotic animals. Few will ever see wild penguins sledding downhill to sea on their bellies, giant pandas holding bamboo lollipops in China or tree porcupines in the Canadian Rockies, balled up like giant pine cones.

Nature, with equal mind, Sees all her sons at play, Sees man control the wind, The wind sweep man away.

A lot of people attack the sea, I make love to it.
