Life is full of tradeoffs: If we want more wind farms, we might have fewer jaguars & pumas and less water

See Brazil’s Big Cats Under Threat From Wind Farms: Jaguars and pumas face extinction in Brazil’s northeast as the fast-growing wind power industry frightens them off their land by Luciana Magalhaes and Samantha Pearson of The WSJ. Excerpts:

"Jaguars and pumas are facing extinction in the Caatinga, Brazil’s northeastern shrublands, as Europe and China pour investment into wind farms, puncturing the land with vast turbines that are scaring the animals away from the region’s scant water sources.

Particularly sensitive to changes to their habitat, the jaguars and pumas abandon their lairs as soon as construction work on the wind farms begins, said Claudia Bueno de Campos, a biologist who helped found the group Friends of the Jaguars and has tracked the region’s vanishing feline population. They then roam vast distances across the dusty plains in search of new streams and rivers.

The weakest perish along the way. Others venture closer to villages, where locals have started laying traps to protect their small herds of goats and sheep, often their only form of survival in this impoverished region.

The wind power industry has doubled its capacity in Brazil since 2018, setting the country up to be the world’s fourth-biggest producer by 2027"

"But by helping to solve one problem—climate change—the wind industry risks creating others, warn conservationists. Indigenous groups recently staged protests in Brazil over the installation of turbines on lands they say are rightfully theirs, while environmentalists have also raised concerns that wind farms installed on compacted sand dunes on the northern coast could have damaged underground water reservoirs."

"Since 2009, the number of jaguars in the Caatinga has fallen 40% while the number of pumas has dropped 20%."

"The disappearance of the felines would throw the region’s ecosystem out of whack, leading to a proliferation of animals that serve as prey"
