Conservation

Monarch butterflies are disappearing. Scientists agree that in the last 20 years, populations of the black and orange insect have been in precipitous decline. But there's much less certainty on what’s causing them to vanish.

As each new scientific paper on monarch decline is published, the image becomes slightly less opaque. So far, potential culprits include disease, climate change, drought, deforestation, and nectar plants. Blame has been cast on everyone from loggers to farmers to suburban developers.


Food waste is an expensive problem. The average U.S. family puts upwards of $2,000 worth of food in the garbage every year.

The normally dry northern region of Argentina has a problem of biblical proportions.

Farmers there are struggling with a massive outbreak of locusts. Dark clouds of the green-brown bugs cast shadows when they fly overhead and when they land, they cover the ground.

“It is really, really, amazing when you see the locusts because you see millions of them together,” said Juan Pablo Karnatz, who raises cattle in Santiago del Estero, about 600 miles northwest of Argentina’s capital, Buenos Aires. “When you think they can be more millions flying around, it could be a disaster.”

The persistent decline of honeybees has scientists scrambling to understand what’s causing the problem and how to correct it. Humans may be part of the problem.

U.S. beekeepers report losing about a third of their colonies each year and the figure increased from 2014 to 2015.

Restoring Prairie On The Great Plains

Feb 4, 2016

From the air, the Midwest looks like a patchwork of cropland and pastures. But before the land was turned over to plows and center pivots, most of it was a sea of grass. 

Native grasslands were first plowed by pioneers homesteading on the plains. More land was converted to crops as tractors and machinery arrived on the farm and conversion of land intensified. 

By some estimates, producing our food consumes about a fifth of the nation’s energy supply. It takes a lot of diesel to move tractors and semis around the farm, and electricity to pump water and dry grain. But some farmers are trying to cut back on the coal and gas they use and make our food system more energy efficient.

When winter comes to Greg Brummond’s farm in northeast Nebraska, he spends his days in the machine shed fixing all the things that broke through the year.
