Save the Oceans!

What’s a marine biologist doing talking about world hunger? Well, says Jackie Savitz, fixing the world’s oceans might just help to feed the planet’s billion hungriest people. In an eye-opening talk, Savitz tells us what’s really going on in our global fisheries right now — it’s not good — and offers smart suggestions of how we can help them heal, while making more food for all.

You Can Lower Greenhouse Emissions With a Simple Change in Diet

Want to lower your impact on the environment by reducing the amount of greenhouse gasses emitted to bring you food? Yes, you can ride your bike (or walk, or take the bus) to the grocery store instead of driving, but there’s an even simpler solution: adopt a vegetarian diet.

Researchers in the UK have concluded that the production of meat and animal-based foods produce a ton of waste.

The production of animal-based foods is associated with higher greenhouse gas (GHG) emissions than plant-based foods. The objective of this study was to estimate the difference in dietary GHG emissions between self-selected meat-eaters, fish-eaters, vegetarians and vegans in the UK. Subjects were participants in the EPIC-Oxford cohort study. The diets of 2,041 vegans, 15,751 vegetarians, 8,123 fish-eaters and 29,589 meat-eaters aged 20–79 were assessed using a validated food frequency questionnaire. Comparable GHG emissions parameters were developed for the underlying food codes using a dataset of GHG emissions for 94 food commodities in the UK, with a weighting for the global warming potential of each component gas. The average GHG emissions associated with a standard 2,000 kcal diet were estimated for all subjects. ANOVA was used to estimate average dietary GHG emissions by diet group adjusted for sex and age. The age-and-sex-adjusted mean (95 % confidence interval) GHG emissions in kilograms of carbon dioxide equivalents per day (kgCO2e/day) were 7.19 (7.16, 7.22) for high meat-eaters ( > = 100 g/d), 5.63 (5.61, 5.65) for medium meat-eaters (50-99 g/d), 4.67 (4.65, 4.70) for low meat-eaters ( <  50 g/d), 3.91 (3.88, 3.94) for fish-eaters, 3.81 (3.79, 3.83) for vegetarians and 2.89 (2.83, 2.94) for vegans. In conclusion, dietary GHG emissions in self-selected meat-eaters are approximately twice as high as those in vegans. It is likely that reductions in meat consumption would lead to reductions in dietary GHG emissions.

Supermarket Loves Inglorious Fruits and Vegetables

Just because it’s not good looking doesn’t mean it tastes bad. Growers take their odd-looking fruit and usually sell it to juice, soup, or canneries instead of grocery store. One grocery store chain in France decided to take the produce usually rejected by consumers and make something fun out of it. This marketing synopsis covers what they did:

Intermarché launched the Inglorious Fruits&Vegetables, a film, print, poster and radio campaign, celebrating the beauty of the Grotesque Apple, the Ridiculous Potato, the Hideous Orange, the Failed Lemon, the Disfigured Eggplant, the Ugly Carrot, and the Unfortunate Clementine.
Now you can eat five a day inglorious fruits and vegetables.
As good, but 30% cheaper. The inglorious Fruits&Vegetables, a glorious fight against food waste.

LED Farms Could be the Growing Fields of the Future

As humans flock to cities and the surround them with suburban sprawl we have covered some of the most arable lands in concrete. This has caused problems of food security, access, and sustainability. Urban farming is nothing new and will continue to spread, but what about industrial-scale farming in cities?

A farmer in Japan has taken an old warehouse and modified it into an enamours and efficient farming operation using specialized low-powered LEDs.

The farm is nearly half the size of a football field (25,000 square feet). It opened on July and it is already producing 10,000 heads of lettuce per day. “I knew how to grow good vegetables biologically and I wanted to integrate that knowledge with hardware to make things happen,” Shimamura says.

The LED lights are a key part of the farm’s magic. They allow Shimamura to control the night-and-day cycle and accelerate growth. “What we need to do is not just setting up more days and nights,” he says. “We want to achieve the best combination of photosynthesis during the day and breathing at night by controlling the lighting and the environment.”

Shimamura says that the systems allows him to grow lettuce full of vitamins and minerals two-and-a-half times faster than an outdoor farm. He is also able to cut discarded produce from 50 percent to just 10 percent of the harvest, compared to a conventional farm. As a result, the farms productivity per square foot is up 100-fold, he says.

Food Tank is a Think Tank for Food

Food Tank is a new initiative to bring attention to the complexity of food systems. They aim to educate people about how foods gets from the ground to your table – and how that process relates to the world at large. Here’s a recent release of their’s looking at the positive impact of family farmers:

Family farmers—small and large enhance biodiversity, protect natural resources, and improve local economies. The video highlights how family farmers, small and large, are using innovative agroecological practices to increase yields, improve incomes, and foster environmental sustainability. And Food Tank emphasizes how family farmers are a critical line of defense against economic disparity, water scarcity, deforestation, and extreme weather events.
