Carl Safina Quotes

When two sympatric, closely related species appear to have very similar needs, we may ask whether mechanisms exist that enable them to avoid direct competition. Implicit in this questions the presumption that two species with identical requirements cannot coexist (Gause 1934).

Most of the oxygen we breathe is made by ocean plankton. And when animals left the seas in which life arose, they took seawater with them, in their bodies — an internal environment crucial for cellular survival. We are, in a sense, soft vessels of seawater.

Bottom trawls—large bag-shaped nets towed over the sea floor—account for more of the world's catch of fish, shrimp, squid, and other marine animals than any other fishing method. But trawling also disturbs the sea floor more than any other human activity, with increasingly devastating consequences for the world's fish population.

... I haven’t wanted to write the same book over and over again, so I’ve gone back to what was really my earliest interest, which is what other animals do and why do they do it.
My upcoming book, “Alfie and Me,” is also much more about the human relationship with the rest of life on Earth, why it’s the way it is for us now, and how it was in other cultures, in other times. And it’s really about what kind of relationship with the world we can have when we blur the usual boundary between us and other species. The narrative story is wrapped around a little baby that was near death that somebody found on their lawn and was brought to us, and whom we raised. She decided to stay around our property and to get a wild mate, and to raise young in a that I put up on the outside wall of my studio.

A couple of years ago I was participating as a writing coach in a "sea-mester," sailing 1,000 miles from Hawaii to , while students from Stanford University received lectures and closely supervised instruction and conducted independent projects on high-tech oceanography. These were smart kids, and the professors were superb. Five hundred miles from land, we got into a discussion on whether the ocean is a "wilderness." The consensus: Obviously it is; there was no sign of humanity, not another boat in sight. Everyone savored the thought: wilderness!
But, I reminded everyone, we haven't caught a single or seen a or a . Wilderness? I don't think so. If the were covered with water, you wouldn't see that the buffalo were gone, either. There is no ocean wilderness. The whole ocean feels our effects, through fishing, pollution, dying s, , immortal plastics, oxygen-asphyxiated s, , and .

From the happy-go-lucky days of oil exploration and drilling, when a lot of easy sources were being found and easily managed, we're gotten ourselves into this sort of apocalyptic time. We're willing to destroy almost everything, risk almost anything, and go ahead with techniques for which we have no way of responding to the known problems. And that is truly an addiction in the real sense of the word, an addiction by which people destroy their own bodies to continue to have a supply of something that is killing them.

The bluefin tuna (Thunnus thynnus) is a creature of superlatives. Growing to 1500 pounds (700 kilos), traveling on transoceanic migrations, and reputedly capable of swimming 50 miles (90 km) per hour, it is one of the largest, most wide-ranging, and fastest of animals. To anyone who has seen this saber-finned giant explode through the surface of the sea, it is among the most magnificent.
