The Bonneville Salt Flats are perfect for speed. Every year, cars and motorcycles break land speed records on the flat expanse of the Bonneville Salt Flats. It’s been a tradition for more than a century, and racers have built a thriving community around the salt races. But how did these salt flats form, and why are they disappearing now?

Climate Change: “Don’t Choose Extinction” (U.N.)
A visitor to the United Nations General Assembly has a message about climate change, telling us government-supported fossil fuel subsidies will prove disastrous to our species. The computer-animated Frankie the Dinosaur (voiced by actor Jack Black) stars in this message produced by the U.N. Development Program as part of its “Don’t Choose Extinction” campaign, timed to the COP-26 climate conference in Glasgow.
Nature: Belize Converts Debt To Protect 30% Of Its Coral Atolls, Barrier Reef
The Belize Barrier Reef System features three of four coral atolls in the Atlantic, lush mangrove forests, numerous offshore islands, and one of the most extensive seagrass areas in the Caribbean. It hosts 77 species listed as threatened by the IUCN, including a sizeable population of West Indian Manatees.
Now, Belize has reaffirmed its environmental leadership by becoming the first country in the Americas to finalize a debt conversion for ocean conservation—and one that represents an impact investment for marine protection that’s unprecedented in scale. This commitment will enable Belize to restructure approximately US$550 million of external commercial debt—an amount that represents 30 percent of the country’s GDP—and reduce the national debt by 12 percent.

Environment: Investing In Carbon Capture Systems
The system could be one answer to slashing Earth’s carbon emissions. A Swiss startup has created a giant vacuum cleaner to capture carbon dioxide from the air, helping companies offset their emissions. WSJ visits the facility to see how it traps the gas for sale to clients like Coca-Cola, which uses it in fizzy drinks. Composite: Clément Bürge.
Renewable Energy: The Political Backlash (WSJ)
Political battles at the most local levels are slowing the pace of decarbonization Property owners in the windy and sunny parts of the U.S. are pushing back against large-scale renewable energy development, opposition that researchers say could slow the transition to a cleaner economy.

Conservation: The Marble Quarries Of Carrara, italy
Italy’s Carrara marble quarries are a source of controversy, pitting nature against economic gain. Environmentalists warn of overexploitation, while others defend the jobs these Tuscan quarries provide.
Franco Barratini quarries marble blocks that sell for €4,000 per ton. The amount of marble that was once quarried in a month can now be extracted in just three days, and environmentalists are alarmed at the consequences. Marble dust leaks into groundwater, turns rivers milky-white and hangs in the air. The effects of this are still not completely clear.
Sandro Manfredi is fighting what he sees as severe overexploitation in the marble quarries of Tuscany’s Apuan Alps. In 2018, he filed a complaint against an illegal marble quarry, and afterwards was nearly killed when someone tampered with his car. Carrara has experienced four floods in the last nine years. Environmentalists blame marble quarrying, which has increased dramatically thanks to rapidly evolving extraction techniques, upsetting the region’s hydrogeological balance.
Analysis: The Western U.S. Drought’s Major Impacts
Watering the Country’s Food Basket Is Becoming a Challenge
Droughts are part of a natural cycle of water. But the drought currently gripping the Western U.S. has climate scientists concerned that the cycle may be shifting. This has major implications for those who rely on the water the most: farmers and the communities they surround. Photo Illustration: Carter McCall/WSJ
