Salt Water Employed to Foil Invasive Species



”There is growing evidence that this step—ahead of more-aggressive treatment rules that will begin to be phased in next month—is protecting the lakes' ecology. Some scientists hail its effectiveness as a rare piece of good news in the decades-long fight against invasive species, which have cut into sport and commercial fishing stocks and fouled intakes for power plants and other industrial users.”

The Status of Our Oceans

”With an ever-accelerating tide of human impact, the oceans have changed more in the last 30 years than in all of human history before. In most places, the seas have lost upwards of 75 percent of their megafauna—large animals such as whales, dolphins, sharks, rays, and turtles—as fishing and hunting spread in waves across the face of the planet. For some species, like whitetip sharks, American sawfish, or the once “common” skate, numbers are down as much as 99 percent. By the end of the 20th century, almost nowhere shallower than 3,000 feet remained untouched by commercial fishing. Some places are now fished down to 10,000 feet.”
