What happens after the Arctic melts? There’s much to do, and not enough capital to go around. That means countries with deep pockets, deep ambition and no Arctic coastline—namely China—can get a seat at the table, too. Who can build their projects first, and who funds them, will go a long way in determining which countries are best positioned to exert economic dominance in the region over the coming decades. Our interactive graphics show how.

America’s worst graveyard shift is grinding up workers. Cleanup at the slaughterhouse is as dangerous as it is repulsive, and the immigrants who do the work are under pressure to complete it faster than ever. No one knows how many sanitation workers get sick and injured on the job, according to the congressional watchdog. But hundreds of pages of government reports and other investigative documents obtained by Bloomberg point to a dark place in the industry. A protein boom could make matters worse. 

Welcome to the marijuana capital of Canada, pop. 8,885. In Smiths Falls, Ontario, the old chocolate factory is now the growhouse and pot plant, and Canopy Growth Corp., the world’s largest publicly traded cannabis producer, is now the town’s largest private-sector employer. The arrival of the company, a darling of Canada’s benchmark stock exchange, has put the town on the rebound. Now it just needs a new hotel, Canopy’s CEO says—perhaps for the Californians who still can’t buy legal pot come Jan. 1.

Trump went after Amazonand immigrants again. Tweeting from his Florida golf club, the president wondered why the U.S. Postal Service didn’t charge Amazon, a favorite target, more to deliver its packages. He also insisted any legislation to protect immigrants brought to the U.S. as children include both funding for a border wall and new limits on legal immigration. He called immigration based on family ties—as when naturalized citizens petition for green cards for relatives—“horrible Chain Migration.”

South Florida’s real estate reckoning could be closer than you think. When will the risks of climate change begin to hurt home values in hot coastal markets? In South Florida, there’s not enough land, high enough above the water, for residents to pull back from the rising seas, and by the end of the century, almost a half-million Miami homes could be underwater. Bloomberg checked in with some people it had spoken with before Hurricane Irma to see how the storm affected them and what their experiences augur.

Trump's administration isn't killing nearly as many regulations as it claims. Of the 67 deregulatory actions it said this month it had taken, almost a third actually were begun under earlier presidents, a Bloomberg review found. Others strain the definition of reducing the burden of regulation or were relatively inconsequential—the kind of actions government takes routinely. The administration has had some successes in its effort, but mostly it's just delayed implementing rules or begun the lengthy process of killing them—actions a successor could easily overturn.

The Tucker Sno-Cat, with its bright-orange coat and its four massive treads, can float atop giant drifts of powder. (Think snowshoes meet monster truck.) And demand for the machines, both new and used, is peaking, thanks to affluent landowners, classic collectors, and gearheads with a love of snow. In the world of transportation, it's one of the moment's most fascinating niche markets.
