There's no easy way to track all of the world's crops. What's missing, among other things, is an accurate map showing where they are.
But the people behind Geo-Wiki are hoping to fix that, with a game called Cropland Capture. They're turning people like you and me into data gatherers, or citizen scientists, to help identify cropland.
American pioneers saw the endless stretches of grassland of the Great Plains as a place to produce grain and beef for a growing country. But one casualty was the native prairie ecosystem and animals that thrived only there.
Some biologists are trying to save the prairies and they've picked a hero to help them: the black-footed ferret. In trying to save this long skinny predator with a raccoon-like mask, the biologists believe they have a chance to right a wrong that nearly wiped a species off the planet.
There is a broad scientific consensus that to keep global warming in check, we need to phase out 80 percent of all oil, coal and natural gas by midcentury. President Obama has set a nonbinding target to do precisely that.
There are technologists who say this national goal is well within reach, but there are also economists who are quite pessimistic about those prospects. And you can find this range of opinion on the University of California, Berkeley campus.
ARI SHAPIRO, BYLINE: It's ALL THINGS CONSIDERED from NPR News. I'm Ari Shapiro. The 2013 Atlantic hurricane season ends tomorrow. It'll be remembered as one of the quietest on record. Since June, there have been just two hurricanes, both were relatively weak. As NPR's Jon Hamilton reports, forecasters were expecting something very different.
JON HAMILTON, BYLINE: The National Oceanic and Atmospheric Administration told Americans to expect an unusually active year with between seven and 11 hurricanes. Other forecasters offered variations on that theme.
Flying to or from Europe, many a transatlantic traveler has gazed down at the brilliant white surface of Greenland and maybe wondered what is beneath those massive sheets of ice. Well, scientists have discovered jagged mountains, ravines that rival the Grand Canyon.
And now NPR's Richard Harris reports that for the first time they've come across some lakes under the ice as well.
The state of New York effectively has a moratorium on hydraulic fracturing as the government figures out how to regulate the controversial drilling technology. Still, the state is benefiting from a fracking-fueled drilling boom in next-door Pennsylvania.
For decades, oil has been the fuel of choice for thousands of residential buildings in New York City. But now there are fewer chimneys spewing black smoke. That's because the city has a program encouraging owners to convert to cleaner-burning natural gas.

The decision to give up entire food groups can be a radical attempt to reform an unhealthy diet, as former President Bill Clinton demonstrated when he revealed in 2011 that he'd gone vegan, after heart bypass surgery.
But more often in this day and age, eschewing animal products is political.
And so that's why we were interested to read that former Vice President Al Gore, one of the world's most famous environmentalists, had — like his former boss — gone vegan, too.
Across the world, countries make very different investments in the environment. We're not just talking about measures to combat global climate change. We're talking about investments in clean water, forests, biodiversity. NPR's social science correspondent Shankar Vedantam joins us regularly to share interesting new research, and he's here to tell us about an unexpected factor that seems to influence environmental stewardships. Shankar, welcome back.
The United Nations negotiations in Warsaw over a climate treaty are moving at glacial speed — and that's in part because there's a fundamental problem.
In the coming decades, carbon dioxide emissions from China, India and other rapidly developing countries are expected to grow quickly. Residents there aspire to lifestyles Americans and Europeans enjoy today, and those nations aren't willing to slash emissions, because doing so could slow their economic growth.
Methane is the source of the gas we burn in stoves. You can also use it to make plastics, antifreeze or fertilizer. It comes out of underground deposits, but it also seeps up from swamps, landfills, even the stomachs of cows.
And while methane is valuable, a lot of it gets up into the atmosphere, where it becomes a very damaging greenhouse gas.

The U.S. lost an average of 80,000 acres of coastal wetlands from 2004 to 2009, according to the latest data published by federal agencies. More than 70 percent of the estimated loss came in the Gulf of Mexico; nationwide, most of the loss was blamed on development that incurred on freshwater wetlands.
"The losses of these vital wetlands were 25 percent greater than during the previous six years," NPR's Elizabeth Shogren reports for our Newscast unit. She also notes that the loss equals "about seven football fields every hour."
Many organic farmers are hopping mad at the U.S. Food and Drug Administration, and their reason involves perhaps the most underappreciated part of agriculture: plant food, aka fertilizer. Specifically, the FDA, as part of its overhaul of food safety regulations, wants to limit the use of animal manure.
"We think of it as the best thing in the world," says organic farmer Jim Crawford, "and they think of it as toxic and nasty and disgusting."
NPR's Richard Harris has covered the U.N. climate talks since the first treaty was negotiated in Rio de Janeiro in 1992. He's monitoring these new talks, and he joins us now to talk about this long-running argument over climate-related funding for the developing world. Richard, thanks for being here.
RICHARD HARRIS, BYLINE: My pleasure.
BLOCK: And we just heard Mr. Khan mention this goal of $100 billion in aid per year, starting in 2020. He thinks that's realistic. What does it look like from where you sit?
This is ALL THINGS CONSIDERED from NPR News. I'm Robert Siegel.
MELISSA BLOCK, HOST:
And I'm Melissa Block.
We're going to spend the next few minutes talking about climate change and a campaign being waged by some of the world's poorest countries. U.N. climate talks are underway in Warsaw right now. And there, a group of developing nations is demanding that wealthy countries accept responsibility for global warming, provide financial support and pay for losses due to climate change.

This year, Americans are expected to buy more than $30 billion worth of organic grains, produce, coffee, wine and meats.
Some producers of farmed fish want the chance to get a cut of those profits, and retailers, who can charge a premium price for organic farmed fish, are with them. But an organic label for aquaculture is not coming easy.

Scientists have discovered a pocket of ancient seawater that's been trapped underground near the mouth of the Chesapeake Bay since the time of the dinosaurs — strong evidence that the Atlantic Ocean was once much saltier than today.
The Environmental Protection Agency today proposed to scale back the amount of renewable fuels in our nation's gasoline supply, biofuels like ethanol made from corn. The EPA is responding, in part, to oil companies that say they're already taking as much ethanol as they can. They say any more and it will hurt quality. But there's another reason for the EPA's action. As NPR's Elizabeth Shogren reports, cheap biofuels haven't been developed as quickly as hoped.
About two-thirds of the world's grasslands have turned into desert. Allan Savory has devoted his life to stopping it. He now believes that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.
Trout fishing is a magnet that draws people from around the world to places like Ovando, Mont. Just ask the owner of Blackfoot Angler and Supplies, Kathy Schoendoerfer.
"Every state in the nation has been through this little shop in Ovando, Montana, population 50," says Schoendoerfer with a mix of pride and perhaps a little fatigue. "And we've also had everybody from Russia, Latvia. We get a lot of Canadians, France, Finland, Brazil, Scotland, Germany, South Africa. We get a lot of business out here. You know, fly-fishing is huge."
Food labels have become battlegrounds. Just last week, voters in Washington state narrowly defeated a measure that would have required food manufacturers to reveal whether their products contain genetically modified ingredients.
Supporters of the initiative — and similar proposals in other states — say that consumers have a right to know what they're eating.
But there are lots of things we might want to know about our food. So what belongs on the label?
Farm programs will likely cost the government less under any new farm bill, but the policy could be bad for the environment. Both House and Senate versions would end a big subsidy, called direct payments, that has paid money to land owners — whether they needed it or not — if they complied with certain conservation regulations. The two chambers' versions of the bill differ on how, or even if, to incent farmers to take care of their land. But both versions would stop funding to keep at least five million acres of land out of production.
In the mountain streams of the American West, the trout rules. People don't just catch this fish; they honor it. And spend lots of money pursuing it.
But some western trout may be in trouble. Rivers and streams are getting warmer and there's often less water in them. Scientists suspect a changing climate is threatening this iconic fish.
I joined two such scientists from the U.S. Geological Survey as they drove up a mountain road in Montana, in the northern Rockies, a place dense with stands of Douglas fir and aspen trees and braided with mountain streams.
Florida — especially South Florida — is very flat and very low, and in places like Miami Beach and Key West, buildings are just 3 feet above sea level. Scientists now say there may be a 3-foot rise in the world's oceans by the end of the century.
Choking back tears, Yeb Sano speaks of the devastation in the Philippines
His eyes filling with tears and his voice choking with emotion over the disaster inflicted on his country, the delegate from the Philippines pleaded at U.N. climate talks Monday for his colleagues from around the world to agree on ways to reduce the greenhouse gas emissions that scientists blame for global warming.
