The West Gets 500% Dustier


dustbowl.jpg The west wasn’t always so dusty. It got a whole more so in the past 200 years, 500 percent more so—thanks to American expansion, complete with trains, ranches, and livestock. Sediment records from dust blown into alpine lakes in southwest Colorado’s San Juan Mountains over millennia indicate the sharp rise in dust deposits beginning in the middle of the last century. “From about 1860 to 1900, the dust deposition rates shot up so high that we initially thought there was a mistake in our data,” said geologist Jason Neff of the University of Colorado Boulder. “But the evidence clearly shows the western U.S. had its own Dust Bowl beginning in the 1800s when the railroads went in and cattle and sheep were introduced into the rangelands. There were an estimated 40 million head of livestock on the western rangeland during the turn of the century, causing a massive and systematic degradation of the ecosystems.” The 1934 Taylor Grazing Act imposed restrictions on western grazing lands, and the deposits show a coinciding decrease in dust that continues to this day.

Another reason to bring back the bison.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

Headshot of Editor in Chief of Mother Jones, Clara Jeffery

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
