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.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
