The world's soils could store an extra 8 billion tonnes of greenhouse gases, helping to limit the impacts of climate change, research suggests.

Adopting the latest technologies and sustainable land use practices on a global scale could allow more emissions to be stored in farmland and natural wild spaces, the study shows. 

When conjuring up an image of a healthy ecosystem, few of us would think of a modern city. But scientists are increasingly recognizing that the majority of ecosystems are now influenced by humans, and even home gardens in urban landscapes can contribute important ecosystem services.

Food waste is a huge global problem. About a third of the food produced globally for human consumption, approximately 1.3 billion tons each year, is wasted or lost, according to the U.N. Food and Agriculture Organization (FAO). Food losses in industrialized countries add up to roughly $680 billion, with $310 billion in losses in developing countries. Produce (fruits and vegetables plus roots and tubers) have the highest rates of waste. 

Taiwan has a simple solution to reduce food waste: Feed it to livestock. The Guardian reports that Taiwan is “one of a handful of countries that have institutionalized the practice” of feeding food scraps to livestock. About two-third’s of the country’s food waste is fed to its 5.5 million pigs. Pigs are Taiwan’s biggest source of meat.

“We realized there was a lot of kitchen waste and that if we put it in incinerators it would hamper incineration because it’s wet,” Chiang Tsu-nong, deputy inspector general with the government’s Bureau of Environmental Inspection, told the Guardian. “And Taiwan’s land is limited, so if you build a landfill or an incinerator people will protest.”

A team of scientists is exploring an unusual source of electricity -- damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida.

Usually the word “jail” brings some harsh imagery to mind: barbed wire fences, orange jumpsuits and tall concrete walls. That’s not the case in the Key West, though. Ask a local about the jail, and the most likely image is Mo, an adorable and charismatic sloth who’s become the unofficial mascot of the Stock Island Detention Center, which doubles as a sanctuary for unwanted animals.

“All the animals here are either abandoned, abused, confiscated or donated,” Jeanne Selander, the caretaker for the facility, explains to Care2. “The animals are here because they need a forever home and we give them one.”

Depending on the source, anywhere from 20 to 40 percent of produce in America ends up wasted. One reason why so many fruit and vegetables are thrown out is because they do not conform to what retailers and consumers believe fresh food should look like. Tomatoes too wide for a hamburger bun, carrots that look like something out of an anatomy textbook, and cucumbers that dare to be curved almost never make the shelves at grocery chains from Walmart to Whole Foods. But Whole Foods, the supermarket that has arguably made organic and socially-conscious foods mainstream, announced that it will start selling “ugly” fruits and vegetables.

Studies of how climate change might affect agriculture generally look only at crop yields — the amount of product harvested from a given unit of land. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.

Around the world, banana farmers are fighting a losing battle against Tropical Race 4, a soil fungus that kills Cavendish bananas, the only type grown for the international market. The disease was first spotted in the early 1990s in Malaysia, but has now started to wipe out crops in large parts of South-East Asia as well as in Africa and the Middle East.

If you’re like most people, when looking for apples among the plethora of offerings at your local supermarket, perhaps you choose the most visually appealing.

You may have noticed that in comparison with varieties that may be smaller, slightly mottled or have a brown spot or two, the Red Delicious easily wins the blue ribbon for best looking.

Your first bite, however, might remind you that apples are one more thing you can’t judge by first appearances. The gorgeous apple that for 70 years was everybody’s first choice for lunchboxes and teachers’ desks has literally fallen by the wayside.

The National Oceanic and Atmospheric Administration says last month was the warmest January on record. That sets off alarm bells for climate scientists, but for the average person living in a northern climate, it might not sound so bad.

That's what many people are saying these days in Russia, where the expected icy winter has failed to materialize this year – to widespread joy. Of course, any climate scientist will tell you that an unusually warm month — or even a whole warm winter — doesn't mean much. It's the long-term trend that counts.
