ANCIENT UNDERWATER CITY

THEY EAT EVERYTHING IN SIGHT Monday, August 14, 2023

In today’s newsletter, we steer clear of damage-inducing disease-spreading feral hogs, learn about the long term effects of wildfire smoke, uncover an ancient underwater city ... and celebrate an African conservation success.

PHOTOGRAPH BY ROLF NUSSBAUMER, NATURE PICTURE LIBRARY They're invaders. Big. Often carrying pathogens. Devouring everything in sight. And ranging over more and more of the U.S. Pigs, swine, hogs, boars. Wild, feral, invasive, non-native. Whatever words you use, these 6 million tusked omnivores are on the loose, stomping farther in the United States than ever before, from Oahu to Texas (shown above) and Mississippi. What damage are they doing? How can they be stopped? A WHOLE NEW WORLD

He can grip up to three fish between his teeth, which helps guard his catch against birds of prey. In this part of Africa, locals have a close-knit relationship with the wildlife—and the wilderness is thriving because of it. A CONSERVATION SUCCESS

PHOTO OF THE DAY

PHOTOGRAPH BY DAVID GEETING Another Florida problem: Between massive pythons, hissing ducks, and green iguanas (one above), Florida has an invasive species problem.

LAST GLIMPSE

PHOTOGRAPH COURTESY MINISTERO DELLA CULTURA Buried treasure: Off the coast of Puteoli, Italy, sits the remains of an ancient marble temple (pictured above), belonging once to desert-dwelling merchants who built cities like Petra in Jordan. The city acted as the most important port in the Roman Empire and shows the extent of its reach. Volcanic activity caused it to sink. ANCIENT UNDERWATER CITY
