You've probably seen the images of dolphins caught in abandoned monofilament fishing nets, or of vast areas of plastic trash floating in remote waters of the Pacific, or of sea turtles consuming plastic bags that look remarkably like one of their favorite foods: jellyfish. Or perhaps, after a rainstorm, you've walked on a beach that resembled a landfill. Some 20 million tons of plastic pollution enters the oceans each year, and it's devastating the marine environment. Plastic litter is also costly.

First "Microcosmos" examined the insect universe, then "Winged Migration" flew with birds and "Planet Earth" took us to the remotest corners of the world. So it is no shock that the visual splendors of "Oceans" are up next, reaching theaters, not by coincidence, on the 40th anniversary of Earth Day. But if the existence of a documentary that records the vastness and diversity of the ocean is hardly unexpected, what French filmmakers and "Winged Migration" veterans Jacques Perrin and Jacques Cluzard have achieved is more surprising and more difficult than might be immediately apparent.

The Atlantic and Indian oceans do not meet at Cape Town, South Africa, as stated by Christopher Reynolds, repeating a common error ("South Africa Calmly Awaits Acceptance by U.S. Travelers," Jan. 29). Instead, they meet about 120 miles southeast of the Cape of Good Hope at Cape Agulhas, the southernmost point of Africa and hence of the Old World landmass. In contrast to the spectacular False Cape and Cape of Good Hope (when not fogbound as usual), Cape Agulhas is rather flat, with many rocks extending far south into the ocean, or oceans.

I don't want to complain, but thousands of people are dumping sewage in our ocean. It hurts the Earth and kills the animals. Ninety-five percent of the water on Earth is polluted. Just 5% left is freshwater. At least we can try to save that tiny 5%. Just put the sewage somewhere else. KIRSTEN HUBBARD Oxnard Editor's note: These Letters to the Editor come from E.L.M. Street School in Oxnard. E.L.M.--Educational Learning Magnet Intersession--is a new school in the Oxnard School District that offers 10-day sessions for students who are between terms in the all-year school system.

Scientists have done the math, and according to their calculations, life on Earth has 1.75 to 3.25 billion years left to thrive. And that's if a giant asteroid or a nuclear war doesn't finish us off first. Yes, there is a big difference between 1.75 billion and 3.25 billion years, but predicting the end of life on our planet is not an exact science, at least not yet. To arrive at that 1.5-billion-year doomsday spread, graduate student Andrew Rushby of the University of East Anglia in Britain created two slightly different equations that estimate the length of time Earth will remain in the "habitable zone" around the sun. A planet is considered to be in the habitable zone when liquid water can exist on its surface.

Tropical ocean waters have become dramatically saltier over the last 40 years, while oceans closer to Earth's poles have become fresher, scientists reported in the current issue of Nature. Earth's warming surface may be intensifying evaporation over oceans in the low latitudes -- raising salinity concentrations there -- and transporting more fresh-water vapor via the atmosphere toward Earth's poles, they said.
