...state of the region around Ukraine’s Chernobyl nuclear power plant, which exploded in April 1986. Despite high levels of radioactivity in the area, biodiversity is flourishing and species are procreating. For Weisman, these examples show that while humans have irrevocably altered the earth’s ecosystem, the evolution of life will continue. Yesterday’s event was the first in a series of discussion-based talks called Green Conversations that are to be held this year by Harvard University Center for the Environment (HUCE). The goal of these conversations is to invite a broad variety...
...species' well-being may affect our own. "Things may not change very much if we lose one more primate species," says Tilo Nadler, director of the Endangered Primate Rescue Center in northern Vietnam. "But where is the limit? ... It is our environment, and primates are part of the biodiversity ecosystem...
...Antarctic Treaty, and a codicil adopted in 1991. It does an admirable job of protecting the land - banning nuclear material, declaring the Antarctic to be a "natural reserve, devoted to peace and science," and prohibiting any mining - but not the surrounding seas, which support a singular ecosystem ranging from krill to penguin, from seal to whale...
...country develops the right and the means to drill for offshore oil in Antartica, and particularly if they hit pay dirt, it's not just that ecosystem that could be endangered. So could the ban on mining on the Antarctic continent itself, which can be lifted by unanimous agreement at any time. That is highly unlikely, but just a couple of decades ago, so was the prospect that the ice caps would melt. The British claim, and those that are sure to follow, amounts to a long-shot move that enables resorting to a future temptation. For the sake...
...since the reservoir was completed in 2006. The rising water is also causing rampant soil erosion, resulting in riverbank collapses and landslides along the shores of the Yangtze's tributaries. Professor Lei Hengshun, an environmentalist at Chongqing University who has devoted years to studying and preserving the Three Gorges ecosystem, says that if the water level of the reservoir reaches its planned height of 165 meters next year, it will bring tributaries of the Yangtze River under even greater environmental threat. "Now it's a good time to review the problems that have arisen," he says, "before a larger flooded...
