CLIMATE CHANGE

An abandoned supertanker holding more than one million barrels of crude oil has been slowly corroding off Yemen’s coast, and a new study out Monday warns that the consequences of an “imminent” spill in the Red Sea could be graver than initially thought — cutting off access to clean water and food aid for millions of people in a matter of days and completely decimating the region’s fishing stocks within three weeks.

PATRICE GREANVILLE—In terms of sheer labor inputs, and engineering difficulties, the Carretera Austral is in a class comparable to the “near miraculous” projects recently seen in China. We wonder indeed how long it would take the Chinese to build this highway across impossible fjords, glaciers, ocean expanses, and all. With their advanced machinery, proven skills, and legendary tenacity, who knows, maybe they would get it done in less time than anyone in the West would expect. Ironically, the “Carretera Austral” Project was pushed against all naysayers by Augusto Pinochet (the road was originally called Carretera Austral Gen. Augusto Pinochet), and may eventually serve to whitewash the dictator’s innumerable crimes. Cynics claim Pinochet saw the project as a gigantic, bottomless pork barrel opportunity for his family and hangers-on. In any case, the ecological price of “developing” this fragile and precious environment is unquestionably bound to be high, perhaps prohibitive, even if the region is only kept as mostly a tourist reserve. The German documentary featured on this page suggests as much: the red tide (“marea roja”) that killed hundreds and possibly thousands of whales, a mind-boggling number for an animal whose numbers remain fragile in the global oceanic ecosystem, is a tragic reminder that the human footprint should not be extended thoughtlessly.

JOHN SCALES AVERY—Today, human greed and folly are destroying the global environment. As if this were not enough, there is a great threat to civilization and the biosphere from an all-destroying thermonuclear war. Both of these severe existential threats  are due to faults our inherited emotional nature.

Our emotions have an extremely long evolutionary history. Both lust and rage are emotions that we share with many animals. However, with the rapid advance of human cultural evolution, our ancestors began to live together in progressively larger groups, and in these new societies, our inherited emotional nature was often inappropriate. What once was a survival trait became a sin which needed to be suppressed by morality and law.

GEORGE WUERTHNER—Much of what is burning in the large California fires as well as elsewhere in the West is not forest at all, but chaparral, grasslands, sagebrush, and non-forested habitat. So “active forest management” would have no influence upon much of the acreage currently in flames.
